How We Tested the Best AR-15 Optics
This guide features AR-15 scopes and optics recommended by the Pew Pew Tactical staff based on our collective experience. This includes reviews, comparisons, training events, competitive shooting, and service in law enforcement and the military. We even own several of these optics.
Testing Protocol
My testing started with an assessment of optical quality. I used a distortion grid to reveal any flaws in clarity, shape, or color. This was also a good opportunity to evaluate light transmission in consistent conditions.
Next, I mounted each optic and got a feel for the controls. Are they intuitive and tactile? Can you use them with gloves? Do adjustments require tools? I made note of any issues that might pop up, either on the workbench or in the field.
Finally, I hit the range for some live fire. I tested each optic in an appropriate setting: close-range carbine drills for unmagnified optics and mixed-range engagements for magnified optics. The proof is in the pudding, so this served as a culmination event that tested every aspect of these optics.
While I didn’t intentionally abuse these optics, I did use them the way I’d use my own: like tools. They got knocked around in a pickup and sprayed with water to simulate the elements. If it was raining or snowing, they got wet. If it was hot, they got baked. I live in the desert, so being blasted by sand and high winds is a given.

Pros
- Clear, distortion-free glass
- Extremely crisp reticle
- Usable with lens caps in place
Cons
- Small brightness control buttons
- Fairly expensive for an unmagnified optic
The Bottom Line
The Aimpoint Duty RDS MR isn't the brand's flagship AR-15 red dot, but I love the balance it strikes between performance and price. Between the all-metal housing and a clear ocular lens cover that lets you shoot with the glass protected, it's one of the more rugged optics I've used. Dollar for dollar, I can't think of a better red dot for your AR-15.
Specs
- Magnification: 1x
- Objective Lens: 18 mm
- Reticle: Multi-reticle (2-MOA dot, 65-MOA circle)
- Illumination: 8 daylight, 4 night vision
- Battery: CR2032
- Dimensions: 2.7” x 1.5” x 1.7”
- Weight: 4 oz
- Country of Origin: Sweden
For a lot of people, Aimpoint rules the AR-15 red dot kingdom. You can agree or disagree, but I’m here to tell you that the Aimpoint Duty RDS MR is one of the best buys in the business. It strikes a balance between performance and price that’s hard to argue with.
The Duty RDS MR occupies the middle of Aimpoint’s unmagnified lineup. It’s about 40% less expensive than the range-topping Micro T-2, but smaller and less battery-hungry than the older Patrol Rifle Optic. Think of this as a duty optic for the value-conscious shooter.
To my eye, Aimpoint offers noticeably better optical quality than other AR-15 red dots I’ve used. The distortion grid confirmed this. The glass is noticeably brighter, more clear, and exhibits less fisheye effect than budget red dots like the Sig Sauer Romeo5 or Vortex Crossfire.
The “MR” in the name stands for multi-reticle. Unlike the base Duty RDS, this one lets you choose a 2-MOA dot, a 65-MOA ring, or both. Multi-reticles are a matter of preference, but I appreciate them on an AR-15 even more than on pistol red dot.
This one is very crisp compared to others I’ve used, and I didn’t see any starburst effect – a big plus for me. There are 12 brightness settings, and eight of them are daylight bright. That’s kind of a less-is-more approach that saves time in a duty environment. I’d rather get to a usable setting quickly than spend more time fiddling around for the perfect one.
The two-button control panel is simple and straightforward, with both accessible from the optic’s left side. This lets you adjust brightness or change reticles without breaking your shooting-hand grip (well, for righties, anyway), but the buttons can be tricky to identify by feel or with gloves on. A little more physical separation would make this interface more duty-friendly.
I do want to give Aimpoint credit for the super-precise and tactile turrets. Each click is firm in the hand and loud to the ear. This is how turrets should be. Just remember to bring the supplied Torx wrench to make adjustments at the range.
The Duty RDS excelled during live fire. I was surprised by how noticeable the difference in clarity – both in terms of glass and the crisp reticle – is between this optic and the more budget-friendly red dots I’m used to. I typically see a little bit of starburst effect from astigmatism, but this reticle looked clean.
I also want to pay special attention to the flip-up lens covers on the Duty RDS. The front cover is solid plastic, as usual, but the rear cover is clear. When you put both covers over the lenses and shoot with both eyes open (which you should with a red dot), you can still see the reticle floating over the target – even with the front of the optic obscured.
This is a massive advantage in austere environments, where you may not want to choose between exposing glass to flying debris and being able to shoot effectively. The “Duty” name is well-earned.
All things considered, I wouldn’t call the price a drawback for the Aimpoint Duty RDS. It’s a fairly expensive red dot, but the performance is worth it. The only change I’d like to see is some more space between the brightness adjustment buttons.

If you have close to four figures to spend, spring for the Aimpoint Micro T-2.
It offers a step up in performance and longer battery life (claimed 50,000 hours vs. 30,000 hours), but the rotary brightness dial is probably the most noticeable upgrade.

Pros
- Available with a red or green reticle
- Better reticle definition than most optics at this price
- Intuitive, ambidextrous controls
Cons
- Slight blue tint
- Basic single-dot reticle
The Bottom Line
Many of you probably want a legitimately good red dot for your AR-15 without spending more than you have to, and the Sig Sauer Romeo5 Gen II is my recommendation. During testing, this value-forward optic performed closer to big dogs than the price might have you believe. While it's not going to replace those optics, it's a good piece of gear that you can own and use with pride.
Specs
- Magnification: 1x
- Objective Lens: 20 mm
- Reticle: 2-MOA red dot, 2-MOA green dot
- Illumination: 10 daylight, 2 night vision
- Battery: CR2032
- Dimensions: 2.76” x 1.57” x 2.44”
- Weight: 6 oz
- Country of Origin: China
What are you to do if you want a great AR-15 red dot but don’t want to spend a huge chunk of your paycheck to get one? Time and time again, we keep reaching for the Sig Sauer Romeo5 Gen II.
This is a great option for AR-15 pistols or carbines that are primarily going to be used for close-quarters training or home defense.
Optical quality is fairly standard for the price – maybe even a little better than average. No, it’s not on par with Aimpoint glass, but neither is the price. There’s a noticeable blue tint and a bit of fisheye distortion, but nothing that will throw you off target at red-dot engagement distances.
The Romeo5’s reticle is simple and effective: a 2-MOA dot available in either red or green. Sure, I appreciate a well-designed reticle with multiple holds for further or extremely close engagements, but this one works nearly as well for a much more attainable price. Getting it daylight bright in the desert sun was no issue.
Sig Sauer did a great job with the controls on this optic. They sit on the top of the tube, which makes them accessible to either hand. There’s enough space between them that they’re easy to manipulate with gloves on, or when you’re reliant on gross motor skills.
During live-fire testing, the Romeo5 felt instantly familiar; it’s very simple and intuitive to use. I wouldn’t say it’s a drastic improvement over other red dots in this price range, but I do think it’s a little bit better in terms of optical quality and reticle refinement.
I really didn’t find any major drawbacks with the Romeo5 – especially for the price. Sure, I always appreciate a larger window, but 20 millimeters is standard for AR-15 red dots; some are actually smaller. For the average shooter who uses their AR-15 for target shooting and home defense, this is a fantastic choice.

Pros
- Giant window and great glass
- Multiple cleverly designed reticle options
- Dedicated button for night vision brightness settings
Cons
- Burns through batteries faster than a red dot
- Adds more weight and physical mass than most red dots
The Bottom Line
Holographic sights like the EOTECH EXPS3 are significantly more complicated and expensive than a red dot, but shooting with this one convinced me that the money is well spent. While the EXPS3 costs as much as many AR-15s, it'll be right at home on a high-end build. This is one time when I'd happily shell out more money for a premium optic.
Specs
- Magnification: 1x
- Window: 1.2” x 0.85”
- Reticle: Dot, one-dot speed ring, two-dot speed ring, four-dot speed ring, DCR
- Illumination: 20 daytime, 10 night vision
- Battery: CR123A
- Dimensions: 3.8” x 2.3” x 2.9”
- Weight: 11 oz
- Country of Origin: USA
Do you want the best holographic sight you can get? Do you have the money to pay for it? Then get the EOTECH EXPS3 HWS and call it a day. There’s a reason professional door-kickers everywhere swear by this optic.
The EXPS3 is perfect for close engagements, especially in CQB-type settings where peripheral vision and situational awareness are critical.
Optical quality is, in a word, excellent. EOTECH’s glass is free of flaws and exhibits outstanding light transmission. I detected no tint or distortion whatsoever with the distortion grid. Combine that view with an extra-large window, and the visual experience really starts to pull away from other optics. I can see why top-tier military and law enforcement units swear by these.
EOTECH offers five reticle options for the EXPS3, with varying combinations of dots and speed rings. I chose the DCR reticle, which has a 1-MOA dot, an aggressively segmented outer speed ring (only the sides remain), and a chevron at the 6-o’clock position.
When zeroed with 5.56 NATO at 50 yards, the center dot gives an accurate hold for 50 to 200 yards, and the chevron provides a 7-yard hold for CQB. The brackets make the reticle easier to pick up and put on target in a hurry. For the kind of shooting I do with an unmagnified AR-15 optic, this feels just about perfect.
The controls include up and down brightness buttons on the left side of the optic. These buttons sit fairly close together, but they’re recessed and tactile enough to use with gloves.
There’s also a dedicated night vision button that switches from daylight to night-vision-compatible settings with one touch. Most of us don’t need that, but it’s a very considerate feature for those who do.
If you haven’t shot with a holographic sight before, there can be a little bit of a learning curve. Some people dislike the slightly grainy reticle. That appearance can actually help your eye focus on the target, though, and it’s better for people with astigmatism. For my eyes, it works wonders.
If you ever damage or obstruct part of the window of a holographic sight, the reticle will still be visible and functional in the remaining glass – that’s not true for red dots.
The EXPS3 is significantly more bulky than most AR-15 red dots, but it never got in the way during my life-fire testing. I didn’t experience any snagging on gear or bumping into my surroundings. The extra weight wasn’t enough to notice.
The large window and clever reticle, on the other hand, were noticeable. I loved shooting with this optic because it gave me a wider field of view than most red dots and made it easier to transition between multiple targets at varying distances. I also take comfort in knowing that it’s just about indestructible.
As far as I’m concerned, the only downside to the EXPS3 is its price. This is the top of the food chain when it comes to unmagnified AR-15 optics, and it costs more than many AR-15s.
It’s fun to have the same gear that elite military and law enforcement units use, but you can save some money if you don’t need night-vision compatibility.

The EOTECH EXPS2 HWS is more than enough for most recreational shooters, and it makes for one heck of a home-defense setup.
It’s just as durable as the EXPS3 HWS. There are three reticle options: one dot with a speed ring in red, one dot with a speed ring in green, and two dots with a speed ring in red. Power comes from a CR123A battery, and there are 20 daytime brightness settings.

Pros
- Combat-tested, Marine-approved
- No batteries required for illumination
- Simple, effective BDC reticle
Cons
- Not as easy to master as a red dot
- Not as precise as an LPVO with a technical reticle
The Bottom Line
To me, the Trijicon ACOG will always be the king of AR-15 prism optics. It's accurate, doesn't rely on any electronics, and has proven itself to be practically indestructible after decades of combat use. There's a learning curve to shooting with the ACOG, but the view is worth the climb.
Specs
- Magnification: 4x
- Objective Lens: 32 mm
- Reticle: Chevron BDC
- Illumination: Fiber optic
- Battery: None
- Dimensions: 5.98” x 2” x 2.3”
- Weight: 15 oz
- Country of Origin: USA
I know LPVOs have taken much of the shine off prism optics, but they still have their place. Maybe this is my internalized generation GWOT talking, but there is no better prism optic than the Trijicon ACOG (or RCO, for my Marines out there).
The ACOG is great for all-purpose AR-15 builds. It’s not as quick as a red dot up close, or as precise as an LPVO with a technical reticle at distance, but it does everything reasonably well. If you want a set-it-and-forget-it optic that you can take to hell and back, this is it.
Once I nestled the ocular lens right under my eyebrow, the ACOG delivered a bright, sharp image worthy of the hefty price tag. The distortion grid revealed the tiniest amount of perceptible pinch distortion, but only at extremely close range. At normal engagement distances, the view is perfect.
Instead of using MOA or MRAD stadia, the BDC reticle has holds for specific distances. Depending on your ammunition, barrel length, and environmental conditions, these holds might be slightly off. Remember that this optic was built for combat – the idea is to get minute-of-man shots off right now rather than spending precious seconds to dial in the perfect ballistic solution.
Illumination comes not from a battery or tritium vials, but from a fiber optic strip that directs ambient light into the reticle. This gives you illuminated holds at 100, 200, 300, and 400 yards. Beyond that, finer, unilluminated aiming references take over. The width of each horizontal line correlates to 19 inches at the designated distance.
The controls are – in the nicest possible way – Marine-proof. Mount the ACOG on your AR-15’s Picatinny rail with thumb screws and tighten them down with a flathead screwdriver or coin. There are no rings to overtighten; no bubble levels required.
Zero the ACOG with the elevation and windage turrets, return the dummy-corded turret caps, and forget about them. The reticle is the only tool you need.
Pro tip: if you want to get really advanced and score some street cred with GWOT vets, slap a piece of electrical tape over the fiber optic. Peel some back to make it brighter, stick it down to make it dimmer. It’s a perfect system.
The ACOG provides quick aiming references from 100 out to 800 yards. On the range, that makes for quick engagements at mixed distances. During testing for this article, I had a blast alternating between 300- and 500-yard gongs as quickly as possible.
At closer distances (think common carbine drills), the bold, red chevron takes center stage. It’s not as refined of an aiming point as a red dot, but it’s good enough for speed work. As is the theme, it’s a balancing act between speed and precision.
By keeping both eyes open, you can train yourself to focus on the target with your non-dominant eye and see the reticle floating in space, the combined image almost unaffected by the magnification your dominant eye sees. It takes practice, but it’s very effective once you get the hang of it. (Or you can mount an offset pistol red dot; your call.)
There’s one primary drawback with the ACOG. After shooting the other optics here, I was reminded how tight its eye box is. I mount mine as far back on the receiver as possible, then put my nose almost on the charging handle. That might feel awkward at first, but it’s the ACOG way.
The ACOG is an acquired taste more so than any other optic here. Mastering it requires time and practice, but it’s possible to run this optic just as quickly and effectively as any other. If you’re willing to put in the training hours, you’ll love owning an ACOG. If you want the easiest pathway to proficiency, you’ll probably prefer a red dot or LPVO.
There are several versions of this optic, so check out our guide to the Best ACOG Models!
5. Primary Arms SLx 3x MicroPrism ACSS Raptor – Best Budget Prism

Pros
- Easy-to-use BDC reticle
- User-friendly controls
- Robust, with minimal moving parts and an etched reticle
Cons
- Elevation holds are very small
- Turret feel is light and vague
The Bottom Line
How did Primary Arms make the SLx 3x MicroPrism so small? It's no larger than a red dot! This little powerhouse is perfect for compact builds, like a budget-friendly AR-15 pistol. Think of this as a red dot that's able to stretch just a little bit further; not quite an LPVO, but definitely capable of delivering more information than an unmagnified optic.
Specs
- Magnification: 3x
- Objective Lens: 23 mm
- Reticle: ACSS Raptor
- Illumination: 10 daylight, 3 night vision
- Battery: CR2032
- Dimensions: 2.95” x 2”
- Weight: 8 oz
- Country of Origin: China
If you appreciate the simplicity, clear reticles, and compact size of prism optics but don’t want to spend ACOG money, I’m happy to report that you have other options. Meet the Primary Arms SLx 3x MicroPrism; the people’s prism.
The best use for the SLx 3x MicroPrism is a build where close-quarters maneuverability is a priority, but you still want some magnification to help with longer engagements. It’s supremely lightweight and compact without being fragile or underpowered.
This optic does well in terms of distortion, with only a slight amount visible around the edge with a distortion grid. There might be a slight blue tint, though, and the grid exposed significant chromatic aberration.
See how the black squares have a thin line of blue on the left and red on the right? It’s pretty severe on the grid, but it’s less of an issue in real life. On the range, I didn’t notice it at all.
The etched reticle is perfectly crisp – I’d be happy with this level of definition at any price. The ACSS Raptor design provides an illuminated chevron, elevation holds out to 600 yards (or meters, depending on which variant you choose), and horizontal holds for wind or moving targets.
It’s a lot of information presented in a very clean display, but it is very small as a byproduct of low magnification. I hope your eyes are good.
Power comes from a CR2032 battery, and there are 13 brightness settings: three for night vision, 10 for daylight. The SLx 3x MicroPrism features auto-shutoff and shake-awake, so you can leave it on your preferred setting and let it go to sleep on its own to conserve power.
Primary Arms opted for a left-side dial instead of buttons to control brightness. This one spins sequentially through the settings, and you can rotate past zero rather than dialing all the way to reach the maximum or minimum setting.
I found the exposed elevation and windage turrets a little challenging. They’re stiff and somewhat gritty, then jump through several clicks at once with very vague feedback. Fortunately, this is likely a one-time nuisance; once the optic is zeroed, you can ignore them. What I do appreciate is a diopter bezel to fine-tune the reticle’s focus.
Live-fire with the SLx 3x Micro Prism reminded me a lot of using the ACOG. The eye box is just as restrictive, which required me to press my face as close to the optic as possible.
The ACSS Raptor reticle is similar, but I found it small enough that using the elevation holds below the chevron required significant mental focus on my part.
The modular base helps with the eye box issue. Eight different spacer combinations let you position the optic wherever you feel most natural behind it. This is a pretty creative solution to a common prism issue.
All in all, I’m impressed by how much capability Primary Arms crammed into an optic that’s actually smaller than most red dots – and I love the price. If you’re building an AR-15 pistol and want a little more visual information at longer ranges, this optic needs to be on your short list.
Aside from cheap-feeling turrets, the main drawbacks are the tight eye box and the relatively tiny reticle. That’s par for the course, though; if you don’t want to deal with it, check out my LPVO picks.
6. Nightforce ATACR 1-8×24 F1 – Best LPVO

Pros
- Excellent optical quality and a technical reticle boost precision potential
- Off setting between each illumination setting
- High-end construction justifies the price
Cons
- I'd love an option with exposed, locking turrets
- You can buy several good AR-15s for this price
The Bottom Line
After using the Nightforce ATACR 1-8x24 F1 several times, I'm a believer in this top-shelf LPVO. This is a great way to get the most out of your premium AR-15. It's tough and easy to use, with a technical reticle that steals the show at longer distances. And the glass? Practically perfect.
Specs
- Magnification: 1-8x
- Objective Lens: 24 mm
- Reticle: FC-DMx MRAD, FC-DMx MOA
- Illumination: 10 daylight, 2 night vision
- Battery: CR2032
- Dimensions: 10.1” x 2.75”
- Weight: 21 oz
- Country of Origin: USA
In a lot of ways, the Nightforce ATACR 1-8×24 F1 is the ultimate AR-15 optic. It’s great at any distance; you can effectively engage with 5.56 NATO, and the build quality justifies the price. This might be as close as you’ll ever get to a State Department SUV and a Pelican case full of SOCOM gear.
The best use case for this LPVO is a 16-inch, do-it-all carbine that has an emphasis on precision at longer distances. If your AR-15 frequently takes on targets at 500 yards or more, the ATACR and its technical reticle will be a tremendous asset.
The optical quality from this glass is a significant step up from almost all the other LPVOs I’ve used.
Light transmission is outstanding, it’s perfectly clear, and there’s just the tiniest perceptible pinch distortion at single-power magnification – you’re not going to see it without a distortion grid placed very close to the objective lens.
At the lowest magnification setting, the FC-DMx reticle looks like a red dot with long, black indicators at the 3-, 6-, and 9-o’clock positions to quickly push your focus to the aiming point. Dial up the magnification, and the technical reticle looks like something you’d see on a precision rifle.
There is detailed information for elevation and wind holds. Measuring targets and impacts is possible, so I felt empowered to unleash my penchant for precision shooting during live-fire testing.
Nightforce gave the ATCR 1-8×24 F1 12 illumination settings: two for night vision, and 10 for daylight. They’re accessible through a dial on the left side, with an off-setting between each brightness setting. I love this approach because it saves time that would be spent clicking through a bunch of settings to turn it on or off.
The brightness and magnification rings require deliberate effort, but not in a taxing way. There’s just enough resistance to make me confident that they haven’t moved without me knowing. When establishing zero, I found the turrets to be very smooth and delightfully clicky.
They’re capped, so you’ll have to rely on the reticle for quick long-range engagements, but you do have the option to install a thread-protecting ring and run them open if you often find yourself dialing for distance often.
There is no parallax adjustment on the ATACR; it’s fixed at 125 yards. While I appreciate the ability to fine-tune my parallax on other scopes, this didn’t cause any problems for me during testing.
Shooting with the ATACR will kind of spoil other LPVOs for you. The optical quality is superb in both low light and broad daylight. Nightforce calls this a “true 1x” optic, and the unmagnified view is indeed very close to what you’d get from a red dot (but with better glass and a larger ocular lens).
At longer distances, the FC-DMx reticle shines. All the information you need is available in a clean, uncluttered layout. It’s a first focal plane reticle, so the measurements remain accurate throughout the magnification range. With second focal plane LPVOs, I sometimes end up using the minimum and maximum settings, but nothing in between.
The main drawback here is price; this is a very expensive way to aim your AR-15. It’s also a little chunky, so it’s not ideal for ultralight builds. Then again, that’s not what it’s for. This is a rough-and-tumble scope for making extremely accurate shots in the worst conditions you can encounter. Lift some weights and save up some cash; the ATACR is worth it.

Alternative LPVOs in this price range include the Trijocon VCOG (successor to the ACOG) and the brand-new Vortex AMG 1-10×24 FFP.
While all three are excellent optics, they each have their own personality compared to the wiz-kid ATACR. The VCOG is simpler to operate and arguably more robust, albeit at a significant weight increase. The AMG just hit the scene, so it’s relatively unproven, but I have no reason to doubt it, and I love the compact size.

As much as I love premium gear, I have a budget just like the rest of you. When it’s time to maximize your budget and leave enough money for ammo and training, it’s hard to do better than the Primary Arms SLx 1-6×24 ACSS Nova.
We often find ourselves reaching for this LPVO when we’re reviewing budget-friendly AR-15 carbines. It’s effective at close distances, capable of reaching as far as most people are able to shoot at their local range, and it offers quite a bit of bang for the buck.
This humble LPVO offers surprisingly good optical quality. There’s little to no tint or edge degradation, and light transmission is totally acceptable.
The distortion grid revealed no issues with chromatic aberration, but you’ll notice a bit of fisheye effect. I could still see that on the range, but only when I was specifically looking for it.
There are a few reticle options. I chose the versatile ACSS Nova for the super-bright center aiming point and MRAD elevation holds.
This is a second focal plane optic, so remember to dial all the way up to six-power magnification if you’re going to use those holds.
Primary Arms gave this scope 11 illumination settings, and they’re all daylight bright. That’s fine with me. If you’re planning on shooting with night vision, you’re not shopping in this price range.
Like most LPVOs, the turrets are capped. Use them to set zero, then leave them alone. The only controls you need to touch on a regular basis are the brightness knob and the magnification ring. I found the magnification ring to be one of the stiffest I’ve used. It would be nice if it were a little bit lighter.
In addition to testing the SLx 1-6×24 ACSS Nova for this article, I’ve used it several times in various AR-15 reviews. Despite being fairly simple in the world of modern LPVOs, it still gets the job done. There are more expensive optics that make my job easier, especially as distance increases, but not enough that you can’t close the gap significantly with training. For most shooters – especially those on a budget or at the beginning of their firearms journey – this is a great way to hit the range and start enjoying your AR-15.
The main drawback for me is the stiff magnification ring, and that might actually resolve itself in time. The reticle isn’t built to go long, but most people aren’t shooting beyond 100 yards, anyway.

Another budget-friendly LPVO worth mentioning is the Vortex Strike Eagle 1-6×24. This one even comes with a scope mount.
How to Pick the Best AR-15 Optics
Popular AR-15 optics come in all shapes and sizes. These are specialized pieces of equipment, so it’s important to choose one that meets your specific needs. Let’s talk about what that means.
Magnification
How far are you planning to shoot? The answer to that question will determine how much magnification you need.
Many people use an unmagnified optic on their AR-15, and it’s almost always a red dot. These optics are affordable, easy to use, and you really don’t need anything else for shots out to 100 yards or so. For some people, that’s the longest distance they have access to at their local shooting range.
Holographic sights do the same job, but at a much higher price. The tradeoff is a more advanced system that’s typically more durable and built for military and law enforcement professionals.
If you’re setting up a home-defense carbine or pistol, a red dot or holographic sight is an excellent choice. Need to shoot a little further every so often? We can help with that — check out our guide to the Best Red Dot Magnifiers.
Prism optics are a great choice for an AR-15 because they’re relatively compact and extremely durable. Etched reticles are easier to see than a red dot if you have astigmatism, and fixed-power magnification simplifies the shooting process (fewer parts also mean fewer potential points of failure).
You can spend a bunch of money on the battle-proven Trijicon ACOG, but you don’t have to. Manufacturers like Primary Arms make some affordable prism optics that won’t drain your wallet.
A low-power variable optic, or LPVO, offers the best of both worlds. These scopes offer variable magnification from single-power up to six-, eight-, or even ten-power for better target identification and increased precision.
These are significantly larger and heavier than red dots or prism optics, but many people gladly accept that tradeoff for the ability to have such a versatile system.
Reticle & Illumination
A reticle is the visual aiming tool inside an optic. Sometimes, it’s a simple dot; other times, it’s a complex array of measurements and symbols stacked up like a Christmas tree.
Unmagnified optics, like red dots and holographic sights, use very simple reticles. In some cases, like certain EOTECH reticles, there might be multiple aiming points.
Prism optics often have a similar style of reticle. Some, like the Trijicon ACOG, have a bullet-drop-compensating (BDC) reticle that provides holds for certain distances. These are positioned based on specific ballistic calculations, so they may or may not be exactly correct for your specific firearm.
In variable-power optics, reticles can be first or second focal plane.
First-focal-plane (FFP) reticles grow and shrink proportionally throughout the magnification range, so wind and elevation holds remain consistent. Second-focal-plane (SFP) reticles do not change. The center point is always usable, but any holds on the reticle will continually shift in value, so you’re best off only using them at full magnification.
Measurements and adjustments can be in minutes of angle (MOA) or milliradian (MRAD). This is kind of like using inches or centimeters; both units of measure work, and which one you pick is really a matter of personal preference.
Just remember that if you’re using one and your friends are using the other, you’re going to be speaking two different languages.
Size & Weight
Once you decide how much magnification you’re looking for, you can start thinking about how much mass you’re willing to add to your AR-15. More gadgetry doesn’t always equal a better firearm, so pick what works best for you.
Most unmagnified AR-15 optics are very compact and lightweight. EOTECH’s holographic sights are about as bulky as they get.
Prism optics can be about the same size as a red dot, although the additional glass will tack on a few more ounces. The Trijicon ACOG is fairly heavy for a prism optic, but it’s still lighter than a variable-power scope and mount.
Picking an LPVO will add the most weight and bulk to your AR-15, but it’s not all bad news. You’ll gain the ability to change magnification settings with the twist of your wrist.
Cost
Only you can decide what’s affordable, but it’s important to understand what you’re getting for your money.
Top-shelf optics from brands like Aimpoint, EOTECH, Nightforce, and Trijicon are built to an extremely high standard. They’re accurate and durable enough for combat, and many of them have earned massive government contracts. Long story short, they can handle what you dish out.
But you may not need that kind of optic. If you’re planning on a few range days a year and using your AR-15 for home defense, there are lots of red dots, prism optics, and scopes that will do everything you need for a fraction of the price. Don’t let online snobbery pressure you into maxing out your credit card on something you don’t need.
Final Thoughts
If you ask 10 people what the best AR-15 optic is, you’ll probably get 10 different answers — maybe more. That’s because we all have different priorities and goals.
This list gives you some of my all-time favorites. Something here should be just what you need, and you might even have multiple options.
As always, get some range time and then come back to let us know what you think in the comments!

We need a section on best night vision scopes and IR lights for close quarters.
How do you not talk about the HoloSun ARO or the HM3X. Price point same as Sig Romeo5 and a better red dot and magnifier.
The Aimpoint sights are excellent, intuitive, and easy to work with.
If you’re going to 300 yards and beyond, I’d recommend going with the Vortex LPVO scopes: for the AR-15, I’d also add that 1-6 magnification is more than adequate unless you intend to go out to 500 yards, and in that case 1-8 might suffice.
EOTech holographic sights, I’d avoid. They’re bulky and unreliable, problematic at best. You could do better with a Holosun sight.
Trijicon’s ACOGs are great when you first buy them, but the customer service is probably the worst in the firearms industry. If you’ve had good luck with them, you’ve apparently cracked the code. All the best!
Last of all, I’ve seen people come out for training who have equipped their rifle with 20-35 magnification scopes — and they never complete timed drills because their magnification is too high and their field of view is so narrow. It’s embarrassing to see them struggle so much — but they miss the point: AR-15s aren’t that accurate… stick with the lower-power magnification.
Hi, what does anyone think to using a scope from PARD the DS35 70 LRF 5.6x on my Smith & Wesson M&P AR15 .223 calibre ? Thanks
This article provides a solid overview of the best AR-15 scopes and optics, with a helpful breakdown of options across different price points and shooting needs. I appreciate the detailed recommendations, especially for budget-conscious shooters with the Sig Sauer Romeo 5 and the Aimpoint Micro T-2 for those seeking premium features. The focus on versatility with the Primary Arms SLx 1-6x ACSS and more specialized options like the Vortex Strike Eagle for competition is useful. However, while the article does a great job covering a wide range, it could have included more in-depth comparisons between similar products to help readers make more informed choices. Thank you.
Another red dot I would recommend is the Vortex Crossfire. It is lower priced(around $200) and I have never had any problems. Comparable to my Sig Romeo5 I like the crossfire more though it does cost a little more.
Also, Unity has some great mounts for magnifiers among other things. They are high quality and would recommend to anyone.
Best low power variable is Vortex? Wow. There are so many better options! Trijicon, EOTech, even Leupold - but my favorite is Nightforce NX8.
Even your LPVO review article was all about Primary Arms and Vortex. Are you budget constrained, or do you have something against these premium brands?
I just purchased a new Springfield Saint AR with the A2 front sight. I did also get, not installed yet, a new Sig Romeo5, green dot optic. Will this be ok using this with the A2 front sight ?
Last time I checked the EXPS2 didn’t have 30,000 hours of battery life
Eric, you didn’t mention any optics from Holosun. Do you only review what you are paid to review or do you just randomly select what you write about?
Hey Ken, thanks for the feedback. We typically write about our favorite products and what we have actually tested. We are continually updating articles and swapping products in and out depending on what we like and what's new. So these recs change. (We love Holosun, they're in several of our reviews and pistol-related articles.) So if we don't include a specific brand/model, it's nothing against them. We can't list everything we like or this article would never end. And we are not paid to include any brand or model on the list. Thanks for reading!
You show Amazon as a source for the SIG Romeo 5 red dot. I ordered one from them and returned it because it was a Chinese knockoff.
I have a SIG Romeo 5 on the DDM4 PDW with Magpul off-set iron sights and a Primary Arms 1-8 LPVO on the AR.
No Holosun optics? As much as it's touted all over Al Gore's internet, and not included here? Makes no sense.
I wish you would identify country of origin in your reviews (many of these sights are made overseas, most troublingly in China). That matters, especially in the long run. (We Americans really need to support domestic manufacturing for these products (and, no, I have zero affiliation with any manufacturers, I'm just a combat vet who knows that ultimately we can only count on ourselves.)) At the very least, that way consumers can make a better informed decision.
100% Agreed!
Do you have a recommendation?
On my handy little truck AR I have a Sig Romeo 5, nice sight for the price and doesn't seem to mind being jostled in the truck.. The next AR up I just got will either get the MRO HD or the new Aimpoint Duty RDS, waiting for a few more reviews for the Aimpoint before deciding. The AK is running an EXPS3 EOTech, bomb proof sight for a bomb proof gun. My last sight is a bit old school. I liked the simple 4X sight like the Vintage Weaver K from better times.
Though I don't want to be stuck there totally. I was looking for a fixed 4X with 30mm tube and a 40-42 something objective lens. Prism need not apply. Closest thing I could find is the KAPS aptly named classic line. I went for their 4X36. They have a 6X42 which has the objective lens I would of liked on the 4X. They also have an 8X56 and a couple variables in that line up. Usually hard to beat German glass and can't wait till Aug for it to get here.
I picked up a Vortex Venom 3 MOA for my .300 AAC SBR (my go to Home Defense weapon), back when they were under $200 ($179 with shipping). Picked up Vortex's QR mount a little bit later, which gives me an absolute co witness when the BRISAS are up. Very happy with the crisp dot on it. No issues out to a 100 meters, with 220 gr Sub Sonics.
I've an old Bushnell 1 - 6 x40 scope on my 5.56 AR, I picked up at a LGS GOOB sale/auction for $40. It had a decent scratch on the tube, so it was used as a display. Illuminated Mil Dot. Clear glass even AR high magnification It holds its zero well, but it does eat batteries, even when off. So I usually keep the batteries out when it's stored for any length of time. For what I paid for it, I've no reason to trade up, though I've been looking at SIG's MSR as a swap out for closer work. Being a retiree on a limited budget, these higher end scopes are outside my budget unless I save for a long time.
Appreciate the articlw/review. I'm forwarding it to some friends.
Not much mention about AT3- can typically get their micro red dot and 3X magnifier for < $300 on sale. Not in the same league as the big names and a little heavy as a combo, but surprisingly solid all around. I have two and they are great setups for those on a budget.
Great Article ! For a Combat Rifle or a Hunting Rifle, I would take a 1 - 6 or 1- 8 or 1-10 scope with an illuminated reticle...and a field of view at 100 yards of at least 100 to 140 feet. With long eye relief at 1x it is almost like looking through a picture window with both eyes open. Also if the battery dies that just eliminates the illuminated reticle leaving a perfectly fine working scope with BUIS. I have have Aimpoint and EO Tech and Trijicon and they are great and better than the traditional riflescopes in certain situations but not nearly as good as an all around optic for close range and longer ranges. I always leave my scope when hunting at 1x for that close range shot, longer range shots almost always give me enough time to dial up the scope to its maximum magnification. Thanks again for a great article, now do one if you have not already on thermal optics.
I like a red dot for close, fast on target. For range I prefer a 4X scope. Something along the ACOG but a bit more traditional looking. Use to be a few choice in this but now you find most rated for rimfire ammo only. Kaps makes what I am looking for in they're Classic Line, a 4X36 fixed scope with a 30mm tube diameter.
Any love for the PA SLX-MD25? It's probably the best sub-200 dot I've ever owned, it holds up and manages to look good on a rifle at the same time.
You went over everything very well except one thing… you did not show anything for guys who bought their AR-15 back when they did not have detachable carry handles or no carry handle at all. Now don’t get me wrong, I love having the carry handle and hit my targets with the iron sights it came with just fine from 0-100 yards but a scope would be nice. Where can I find a scope and the mount that sits into the carry handle? I know they make them, I remember seeing SWAT and others with them on their guns.
I googled "carry handle pic rail" and got about a zillion results. Tried to post a link for you but I forgot we can't lol
Well hell, I could have done that. I was looking for a AR guy’s opinion on which one’s are better so I would not have to sift through the crap.
Love the Delta Stryker 1-6 i picked up for my 18" Tavor SAR. Also dig the griffin offsets that I run with a 2.5-10x PA on my 12" Grendel.
Tried Moepta. No thanks. Holosun 510c red dots all day. Tract rimfire is excellent. Wish I never bought eotechs.
MagPul MBUS are nice, but I found Monstrum Tactical has almost a carbon copy at half the price. Look 'em up, they have some awesome scopes at a really great prices too.
Please update for 2021! A lot has changed in the past few years. For me the big game changer is the Vortex Spitfire 2 5x, which combines all the best features of the ACOG-class prism sights with significantly lower weight and price.
Would have been good to mention the Brownells Retro 4x carry handle scope. Unless you think it is not good. After all, some AR owners do have that design.
Need to change the name to Primary Commerical donaters reviews Arms. Cant trust this site anymore im out.
I don't see anyone trying to sell any particular optic on here. Some like a certain brand.
But if you got to go, then you a got to go.
Everyone's opinion is equally as important.
Oh Well.. BYE !!!
Been using Holosun for my AR and handguns I have had no issues with them but clearly you do. Care to explain or is this just a bios commercial site?
What do you think about the Holosun 515 gm for first AR scope? At that price point.
I thought you said that the Primary Arms magnifier was the lightest at 7.9oz?
Surprised you did not even test the Springfield Hex Dragonfly. I have it on my SAINT Victor with an ADM riser mount and it co-witmesses perfectly. Quality plus. A bit more expensive than the Romeo but far superior IMHO.
Burris RT-6
I'm not a Vortex fan (Bushnell usually is better in the same price range). I do like the Spitfire 1x though. I haven't tried the 3x or 6x Spitfire. I've shot deer sized targets at 200yd.s and got regular hits with the 1x and it's currently my favorite in the .223 platform.
I'm surprised you didn't mention the Bushnell AR 4.5-18x40 for a longer range scope. I have one mounted on my 6.5 Grendel and it works really well in tandem with Hornaday's ballistic calculater.
I’m really surprised there isn’t more love for holosun or primary arms on this list.
Would these suggestions be the same for an Ar10 platform? What you’d do with said ar10 varies greatly of course, but let’s say... from hunting to hitting a gong at 300-500?
I meant all around sight or scope if you had to pick one.
I meant AR pistol.
I am new guns in general, if you had one scope to get for an AR piston what would you get?
Piston suggest to me you may be building for longer range performance so check out the Vortex Strike Eagle 1-6x or newer 1-8x model that was not mentioned here. I have both and like them and cost is reasonable for what you get.

I think that it's worth noting that 14. Vortex Viper PST 1-4x is an "mrad" reticle, and it appears that the Viper does not come in "moa" (contrary to what the reticle image shows in this article). Vortex, to my knowledge, released the "Ranger" model as the new version of the discontinued Viper "moa" model (resurrected).
You mention the ACME Machine 6-24x50 in your Grendel upper list.
Magpul BUIS....meh. I prefer either the MaTech or KAC BUIS. Magpul (polymer BUIS windage knob is pretty difficult to move in my experience).
Same with the irons; at least when new.
where can i get the Sig Sauer Bravo 5? I cant find it anywhere or whats the next model up? Thanks
$519 on Amazon
Very informative. Thanks
Your Steiner is discontinued. Wonder why.
Mounting a PA 1-6x ACSS on an Aero M4E1/Atlas S-ONE 16" upper with Magpul MOE SL furniture.
In the Aero Ultralight mounts, would the Extended or SPR work better?
(likely won't use BU sights)
I wear glasses, am near sighted and when I shoot I have a bad habit of closing my right eye. And, I think I have astigmatism. What would be the best red dot or holographic scope for me to put on my Troy AR -15 pistol?
Prismatic. Elcan. Or vortex spitfire. I suffer from it too. Take a red dot to your eye doctor. When the dot stops blurring you got shooting glasses. Or spend 2k. I’m using irons until I can save up. The Elcan 1-4 is unsurpassed and no one talks about them because well. 18” of scope in a 6.75” package.
Eric,
Ever used / tested / tried a Sightmark? I know they are fairly inexpensive, but with a bit of abuse, mine has still always maintained zero.
Would love to spend 2-300 for a red-dot, but I just don't have it to spare.
How about reviewing some made in America products? Made in China is kind of toxic now.
Great article with solid info. I opted for the ACOG TA31 with ACSS reticle, available directly from Primary Arms, because it builds on the original reticle design with better ranging plus leads for wind and moving targets. A little more expensive but well worth it when speed counts.
Eric, I’m curious about your thoughts on Swampfox?
We've had a great experience with their prism optic! We have more reviews of their optics in the works but all of the early reports I've heard from our writers have been very positive.
Hey can you do a article on night vision scope have no idea thks
Where is the SPARC AR from Vortex? Sub $200.00, has the Vortex warranty, and actually has rubber caps for the glass. If I am spending the money on a nice AR build may as well start at the 200.00 range. You get what you pay for.
In the picture at the very top of the article. What is the scope with the RED Directional buttons on it?
It looks like it’s an
ATN X-Sight II HD 3-14 Smart Day/Night Rifle Scope
Good eye!
Do you have a review on the ATN?
I love my V Viper 1-4 the TMCQ reticle rules ! I wish they made it in the 1-6 or 1-8 too! Maybe the Vortex gods are listening-saving now for the 1-10 but wish it were lighter
I would throw the Vortex Strike Eagle 1-8x24 in there seeing as you can get the scope and mount from PSA for $299 when it is on sale, LIKE RIGHT NOW, using code STRIKEEAGLE. Just my .02 plus I have 2 of them and they work great. Looked at Primary Arms and it was excellent. It just uses a different reticle. I prefer the SE reticle and for the price = no brainers. ;)
What website for the 1-8x24 strike eagle scopes?
Palmetto State Armory
Palmetto State Armory! Use code "STRIKEEAGLE" and get the scope and a mount for $300, a really great deal.
I have tried the Vortex Spitfire 3x and the Burris AR-536. I didn't like them, the eye relief was way to short for my tastes, about half of what is advertised I felt. I sold them to a guy that seems very happy with them. That AR is now wearing a Konus Pro T30, 3-12x44 with 30mm tube, very clear and bright. I've only put about 1200 rounds through it but I'm happy with it so far, happy enough I'm going to buy a second one.
Did you have a chance to look at the Meprolight Foresight? Reticles are digitally projected on the glass. Choice of reticles included 1 MOA dot and dot with circle.
What's up man my names Keith. I started hunting at age 12, lol. That was in1979, yep I'm a pap. Anyways my first rifle and the same one I use today, is a 700 bdl in 30.06 flavor. Only the best caliber of all time hands down. Of course i only hunt white tails. Getting off track see i am old. Back then you had 2 choices in optics. Red field or Leopold. If you got caught with a bushnell nobody would take you serious. Here's my pointing still hunt and killed alot of deer. I hunt pa. Ohio and west Virginia. All rough terrain! The reason I still use that setup which I have quite a few other choices
Why I use that, BECAUSE YOU DONT DROP YOUR RIFLE NEVER. Sacrifice a limb before you drop your rifle. No optic would survive that test. If there was such a unicorn that would survive that drop. Nobody could afford it. I'm not judging this is what was pounded into us. It's a different world now, most kids dont give a crap about there most prized possessions, because they dont value shit sorry. Farm kids know what I'm saying. Sorry but I'm direct
No Sig optics made it in this lineup but holosun & vortex did?....Thats funny smh
sig optics are chinese junk.
Their high end equipment is made in New Hampshire.
Would it be unwise of me to buy a 1-6x Trijicon sight if I only plan on using my AR for self defense?
The 1x would be fine for CQB, but a red dot would be better, less heavy, and cheaper.
Not at all, although you may plan on strictly self defense your going to be on the practice range
I have 2 SPARC AR's one is on my 300 AAC the other on a Ruger 10/22. I am considering the holosun for my newest AR, but I also really like having the lens covers of the SPARC. Many of these do not have caps for the glass. Great thing about Vortex is their customer service. This is a crowded field with a bunch of great options.
Eotech and Troy back ups, I guess i'm just old school.
Exactly what I’ve got.
I like the Magpul back ups, but my DiamondHead's are much better. I put the Magpul on my KSG shotgun and the Diamonds on my Daniel Defense.
Kongrat! A very comprehensive article for those who have to make choices based on their needs. (sports or hunting) I have been following you for a short time, but I do it with real pleasure!
What is your opinion on SWAF SS scopes with fixed power?
We haven't gotten to try them yet, but if we do we'll put out a review!
SWAF SS scopes with fixed power RULE. Clear glass, durable, and excellent value.
I just took an SWFASS1 to 4 power through a designated marksman course. I loved it!
Great Article. Very clear and K.I.S.S. writing style.
I ended up buying the Primary Arms 1-6x24 because of this. Excellent, affordable scope.
Did my first Run-N-Gun with it. Hit targets out to 600 yds. with a 100 yd. zero. The ACSS reticle is awesome. It survived going over walls and the dirt.
So glad we could help, Josh!!
Awesome article and comparisons. I know it’s hard getting good shots of reticles with cameras but none the less, good stuff. Keep living the PEW LIFE!!!
Thanks! We're always working on upping our camera game.
Great service the manager Wendy is such a sweet heart I don’t live in tehachapi I love in Bakersfield been working out here in tehachapi doing construction on the new Walmart and during my breaks I have been going and she’s been so help full five stars for Wendy !
5 Stars, Wendy!
What about Trijicon MRO?
No love for the MRO? The Trijicon Mount is trash so go third party. I bought one and it now sits on a LaRue QD mount. By far my favorite optic for anything under 14 inches
on the offset irons, is there a left handed version?
Dueck offers a left-handed version but I've not heard great feedback about them, especially since they are so very pricey. Most of the left-handed shooters I know that run off-set sights use a 45-degree offset Pic rail and a micro red dot.
Why Are there no Trijicon optics on your list ?
The ACOG is built by Trijicon and is on the list!
Hello Mr. Hung, I red a lot of your publications on pew pew tactical, and I really like it, especially for the AR platform. Being a knew owner of a AR-15, precisely the S&W MP15 Vtac II, looking to upgrade for a optic in the vortex spitfire 3x line. My question is have you tried the Bushnell AR750010? Or do you have any other option? Thanks for all your time and effort of doing all those chronicles, it is very interesting and useful. Sorry for the awkward English, I live in Quebec. Regards....
Great review, would like to shoot but dont think I would buy one as my safe is full and it would only be a novelty for me. Thanks for the info
Hi Eric
Looking for advise, recently picked up the ruger 9mm carbine rifle. What optic would you put on, ?
I like seeing my hits, so magnification is needed as i where glasses
Regards
Take a look at the Leupold Mark AR 1 3-9x.
Ultra lightweight. Mrad reticle and adjustment, with a quick 55 grain bdc also on the turret.
Exposed turrets with return to zero adjustments.
I almost bought a much more expensive scope til I started playing with one of these.
Now I’m going to get one for my Rem 700 .308. I think Leupold will customize a BDC to caliber and weight.
I definitely need to play with some Leupolds...trying to get my hands on one or two.
If money is tight NcStar has a scope, i call it my shortie scope. Its half or less length of a standard 3-9x40 and it has cross hairs with tic marks for windage and elevation, as well as crosshairs light up red or green 5 intensity levels each. Its rated for up to 50bmg recoil. Its made in china(of course) but glass is clear and sight picture rivals some more expensive scopes. With 3-9 adjustable magnification and 40mm obj lens 80 bucks was a steal. Its fog and water proof too. You cant beat it for the money. Its made for ar15 and its a generic clone of the 223 scope but i like it and put on my light weight break open 308 win hunting rifle. Its probably not good to go for combat, but hunting, plinking, even comp shooting it should do very well. Thought id throw that in for someone on a budget. I dont know max range as i only hunt deer at max 250 with 95% at 150 or less. It can see clear way farther than my rifle can shoot good.
No Primary Arms optics listed? I consider the PA 1-6x gen3 ACSS reticle far superior to the Strike Eagle, with comparable glass and illumination. Trijicon even copied features from the ACSS reticle, so you know it's legit. :P Strongly recommend Primary Arms to those seeking affordable but solidly built optics. Their 1-4x duplex is also only $120, for a true budget variable option. Theres alsp speculation around arf and other places that they may be built in same factory (strike eagle and PA ACSS) due to near identical external characteristics. Seems to come down to reticle preference.
-i am not an employee of or compensated by PA, I just feel their optics do not get the attention they deserve and try to draw attention to a solid company.
Also, 2.5x, 3x, and 5x fixed magnification prism scopes are great options, and work for people with astigmatism whereas traditional red dots generally do not.
I have a couple of PA optics and like both of them very much. We're working on a large update for the article soon-ish, part of that will include reviews of some PA optics...don't know if they will make "best of" yet though, still in testing!
Looking forward to your findings. I have found the primary arms enhanced red dot to be an exceptional optic. Very robust and absolutely bombproof. And a great value. I find no reason to buy the aim point any longer. You simply cannot break these things.
Update: got some PA optics in hand (1-6x and 4-14x). I'm beginning testing so stay tuned!
Eric,
What do you think of the Vortex Venom for a co-witness sight for an AR-15? I just use it for all around target practice 0 to 200 yards and plinking, etc.
Great optic, solid, and Vortex are one of my goto companies due to their warranty and customer service. Personally, I'm not a huge fan of the Venom on a rifle since it feels a bit small to me - but if you like the look and feel of it, go with it! You won't be disappointed.
Another great article. I have 3 AR's; two full size (16") and one pistol (8.5"). I have a Vortex Strikefire on my Colt, an Aimpoint Comp ML3 on my S&W and a Vortex Sparc AR on my pistol. All have been great and operate flawlessly. That said, if either my Strikfire or Comp ML 3 goes down, I will replace it with the Aimpoint PRO. Anyway, fantastic article - keep them coming!
Vortex Strikefire II is another quality affordable option for under $200. Also gives the option for red or green dot.
Leopold Mark AR 1.5-4x firedot is great option for 3 gun or anyone wanting a magnified optic for their AR. Green firedot basically acts a red dot on lowest magnification.
The SPARC AR doesn't have a rubber housing, its just a molded rubber cover that easily slips off. It has an all aluminum housing. Within minutes of owning this I figured this out.
Really enjoyed this article and appreciate the insights. there is a lot of glass out there and it is good to know what has been tried and worked. Now to scour up some money!
You're so welcome, Rick!
Hey guys, at 44yoa I was diagnosed with early stage wet macular degeneration in my right eye, ofcourse I'm right eye dominant. I'm looking to get a scope for my new M4 and was curious if anyone out there is familiar with my condition and has experience with best scope option? My vision is 20/30 with only a small center blur in right eye, no real issues now. I plan on using it for range n varmint/coyote so I'm not looking for an elaborate sniper scope, more of close range to maybe couple hundred yards. Thanks in advance, James
I can tell you one scope not to buy, well two actually 2. 1st. The luepold vxr patrol 3x9 x 40 the reticle is huge at distance(2nd fp) and glass is far from clear. So not a fan! 2nd is the vortex razor gen 2. After using this scope everything else is sub standard (at least what I own) I am now in a place where I know what good glass is and feel like I won't be able to buy avg. Glass anymore. Spending over $1000.00 on a scope isn't my favorite thing to do but I don't see any other way now. You know what they say, ignorance is bliss.
I think next I'm gonna check out a pm2
I'm kind of surprised that there was no mention of the Primary Arms 3x or 5x prism reticle here, any particular reason or maybe an opinion or review of these products?
Hi Nick, looking to expand this out with some of the more affordable options and fixed mags.
What is the better choice. Trigicon MRO 1/3 cowitness with a Scalarwors QD mount. AIM POINT PRO. AIM PIONT H1. This is for an AR15. Any Suggestions?
Can I use a Bushnell AK red dot on a Colt M4 .... no problems?
It will physically fit...not sure what the actual difference is.
Very good article. I recently purchased my very first red dot. It is a “AT3™ LEOS™ Red Dot Sight with Integrated Laser Sight & Riser”. It was just over $115. I don’t have a lot of experience with it yet, but so far I’m super impressed with the build quality. I was wondering if you have ever done, or would consider doing an article on slings for the AR15. I would be interested in advantages and disadvantages of different designs and materials. I’m new to the AR15. I just bought mine in August. It came with a couple of standard clips. I would be interested in an article on clips. Are there differences (other than capacity). Do some brands have a better reputation. Stuff like that.
Hey Kent, haven't heard of AT3 but glad to hear it's working for you.
Here's our sling article.
It's a magazine Kent. Clips are for guns with an attached internal box magazine. I know it's not a big deal, but using the correct nomenclature sounds better cheers bud, have fun with your new AR.
Thanks!
Did a good job now i have an idea on wat tu put on my SAINT. THANKS
You're welcome, James!
I’ve been rocking the primary arms 3X on my DD and loving it. Very surprised none of their offerings even got a mention...
Hey Jman, we had one of their red dots in our Budget Red Dot Test. It didn't perform the best.
Eric....Nice write up BTW....My question...I am looking for a good quality red dot for my S&W 629 44magnum w/6"barrel...I don't want to break the bank...BUT...I NEED quality and DEPENDABILITY , to handle the recoil.
I'm an old IPSC shooter that "my eyes ain't what they used to be"...Would like as large if sight window/diameter as feasible....What would you suggest?!?.....Thank you for Your Opinion
An awesome article like your others!
I went and played with the ACOG, EOTech, and Aimpoint Micro H-1 this weekend. They match almost everything you said. I loved the optics of the ACOG, but it is really expensive and the fixed mag made closer range shooting seem like it might take an extra half-second to acquire.
I also saw the EOTech HHS II. It's a hybrid system that has an EOTech red dot + a flip on/off magnifier. I was very intrigued by this because it gives the best of both worlds (hopefully?).
Thoughts?
Eric,
Do you know of any offset iron sights for a lefty?
Just Turn them around
Love hearing budget minded, rock solid optics. You stated Burris M tac but why not 536 for an AR? I own one and love it. Vortex version is very similar in the same $ range. Why the MTac? What is one gaining over the 536?
Eric. First time buyer. I am looking at the Vortex Strike Fire 2 and the Atibal MRCD-2 Any thoughts about those. I am in the $2 to $400 range. Great insight. Thanks!
Our 3 gun competition is beginning to set up targets out 200 yards.. I have just upgraded my red dot to the Sig Romeo Mil Spec for my AR-15 but with my 70 year old eyes I need a magnifier at that yardage. Suggestions?
Primary Arms or Riton!
The Vortex 3x magnifier is a solid option, gives reasonable precision out to 300 yards with a 2 MoA dot sight.
Eric,
Great website, great resource - curious for your thoughts for my future optic purchases. I need optics for both a Daniel Defense V11 Pro and Daniel Defense Ambush .308. I've mounted a Swarovski Z8i 2-16x 50 on my Weatherby MK V 300 - and it is absolutely excellent. I haven't seen it yet, but I'm told that the Z8i 1-8x 24 has essentially ZERO compromise at 1x - and would essentially perform like a red dot at 1x, with the benefit of built-in zoom to 8x. The obvious consideration is its a bit heavier - but putting that and price aside, for the best possible on the AR-15, would you go with the Z8i 1-8x 24 or would you still recommend something else? As for the DD AR-10 - again, without a price restriction, your best recommendation?
I've pre-ordered the Vortex 1-6x PST Gen 2 since it was so awesome at Shot show this year. Great at 1x with daylight bright red dot. Unless you're going pretty far distances...I think 1-6x is enough. For the AR-10 I use the Nightforce 2.5-10x NXS. For my bolt gun I run a Schmidt & Bender PMII 5-25x.
Hey there Eric! Again thank you for your work! I've got the Aero Precision complete upper and lower being shipped per your recommendations!!! So for the optic, I was going to get the Viper PST 1-4x for $419 but saw that Vortex just recently come out with the Gen 2 Viper PST 1-6x for $699. Is it worth the $280 difference moving to that 1-6x? I don't want to have to buy another one for another 5 years at least!!!
Hey Grayden, if you anticipate shooting 300+ yards I like the 1-6x more. Plus the one I demo-ed at SHOT was awesome. I have it on pre-order and should have it in a month or two with a full review.
Nice!!! Thank you again Eric for your great work! Because of your site, it gave me the confidence to build my first AR-15 with the Aero Precision lower and upper. Now, I'm in high anticipation of your AR-10 308 Guide.
Thanks Grayden...it's in the works!
I hope you recommend the S&W M&P10 cause I kinda jump the gun and purchased a used one that was priced very well. So, I just purchased a Leupold VX-R 4-12x40mm Rifle Scope for that AR10 but was wondering witch mount would you suggest.Thank you.
We're going to have our Best AR-10 article out soon and I believe that M&P10 is making it in there! For mounts I like the Aero. For quick detach I like Larue.
where can i find the vortex strike eagle for $275?
Hey Mike, thanks for catching that...they are usually around $300.
That is a great scope from an outstanding company. I could not get mine zeroed so I called Vortex. No questions. They just sent me a FedEx label and 2 weeks later I had a new scope (the first had a loose lens). Highly recommended.
Any thoughts on the Aimpoint M4s? I can consistently hit 12"x12" at 600 yards, but what do you think of it?
Hey, I have the CompM3 and love it. I believe the M4 is even more bombproof, takes AA batteries, and is optimized for night vision. If that's what you're looking for you can't go wrong. But it's $900.
Hi Eric,
Any advice for cross dominance RT handed shooter/LT eye dominant) and far sighted shooters (looking to purchase my first AR (Stag Arms M3)? Your articles are very helpful and your website is well put together and easy to access info. I'm actually buying my AR because of your andvise and your articles and my personal research, of course. Thanks again. Keep up the good work.
Hi Daniel, for pistol shooting I use the Chapman stance so my left eye is more centered around the front sight. With an AR, you're pretty much stuck with using your right eye for magnified optics. But with lower magnifications or 1x, I keep both eyes open.
I'm right hand/left eye dominant and mostly shoot long guns left handed. When I'm doing CQB drills,
switching left shoulder to right and back, I've found the eotech the easiest to use FOR ME. Try out a few optics if you can, to see what you like best.
Hi Eric,
Thank you so much for this article.
I bought a TROY P.A.R. 308 Win, and I couldn't decide between the Vortex Viper PST 2.5-10x44 and the Strike Eagle 1-6x24 (cheaper).
My shoot range is between 50 to 300m.
What do you think ?
Would you recommend the vortex sparc 2 over the sparc AR?
Hi Elia, I'm looking forward to trying out the Sparc AR. It's new but has pretty good reviews. Biggest difference is that it takes AAA batteries which makes it a little heavier.
Why no Short Dot?
Ah, another Schmidt & Bender aficionado. I hope to try out the 1-8x Short Dot soon.
What do you think of the AR Maglock device? Is the AR Maglock used instead of modifying your AR with 'featureless" items so you will not have to register it in 2017?
Hi Michael, I haven't had a chance to play around with one. But you can see more info in my Features AR-15 article (http://www.pewpewtactical.com/featureless-ar-15-rifle-grips-stocks-muzzle-devices/)
Hi Eric, amazing article - thanks so much for all this great information. One thing - I'm really interested in the Vortex Viper PST, but according to their site it's a second focal plane scope, not a first focal plane as you mention above (see the Features tab on this page: http://www.vortexoptics.com/product/vortex-viper-pst-1-4x24-riflescope-with-tmcq-moa-reticle). Are you recommending a different scope there or was it a typo? Thanks!
Hi Rick, looks like you're correct...it's second focal plane. I've corrected it in the article. Seems like the Amazon description is wrong. Thanks for catching it!
Hi Eric, maybe I missed it, but for the love scopes, are they ffp or sfp? Any preference for you?
Eric,
Thank you for such an informative series. I’ve referenced it many times as I get into AR’s for the first time.
Picked up a great deal on a S&W 15 Sport II and I’m looking at the Holosun
HS515C
Have you looked into them and if so your thoughts.
Thanks
John U
Hi John, you're welcome! I definitely have heard of Holosun and have seen some fellow competitors run them to great effect. But I haven't played with them myself yet.
