    How We Tested the Best AR-15 Rifles

    For this article, we gathered a bunch of AR-15s we’ve personally shot, reviewed, and owned here at Pew Pew Tactical. All rifles that made this list had to have a few things in common to earn a spot in our recommendations:

    • Must reliably fire, meaning no more than a single malfunction in our testing of 500 rounds or more.
    • Ergonomics must work for most shooters.
    • Must have a price tag that the average consumer can stomach. (We might add a few high-end options, but most of our recommendations come in at a reasonable price point).
    Wyatt AR-15, USCCA
    Wyatt, Jr. Editor, testing out an AR-15 at the range.

    We also tend to prefer AR-15s that work with a variety of magazines and aftermarket mags because that makes life easier.

    The entire Pew Pew Tactical team, as well as freelance writers, contributed to this review to offer different opinions based on body size and experience level. Every review rifle undergoes a strict testing protocol that requires a minimum of 500 rounds of practice ammo and heavier match-grade ammo at 50 and 100 yards with a 5-25x scope (unless otherwise noted). (Although most of the guns listed have seen well over 1,000+ rounds through them.)We require all AR-15s to be tested with at least 3 magazines to assess compatibility, and we use a Lyman Digital Trigger Gauge to measure average trigger pull.

    Guns with hands-on reviews have been linked so you can see more details.

    Pros

    • High-quality CNC and coating of all parts
    • Individually MPI tested barrel and BCG
    • Great thing handguard with Picatinny on top and MLOK on the sides
    • 100% reliable and around 1 MOA accuracy with good ammo
    • Highly regarded brand for resale purposes

    Cons

    • On the steeper end of AR-15 prices
    • Pistol grip angle more geared towards close shooting
    • Trigger could be better

    Specs

    • Barrel Length: 16”
    • Overall Length: 32.25-35.875

    It might be just because my first AR-15 10 years ago was a DD, but mine has never failed me, even after 8k rounds.

    Daniel Defense DDM4V7
    Daniel Defense DDM4V7

    My overall pick for a high-end AR-15 goes to the 16-inch DDM4 V7 which sports a free-float handguard and a softer-shooting mid-length gas system.

    Daniel Defense DDM4V7 Desert Shooting

    We’ve been testing it extensively, and the quality shows even in a sea of ARs.

    Check out our full video and article here of the DDM4 V7 here.

    And in the current firearm craze…they are still pumping them out weekly, although I recommend getting on their email notification.

    If you want to go on the shorter side, try out the 14.5-inch carbine gas system DDM4 A1 with a permanent muzzle device that brings it to 16 inches.

    If you like the front sight block (FSB) options, look at the 16-inch DDM4 V1, which also has a slightly softer shooting mid-length gas system.

    Pros

    • Great bang-for-your buck AR that competes with the DD but saves a little $$
    • Solid build quality with a nice finish
    • Amazing reliability (we had no issues)

    Cons

    • Supply is limited and it’s frequently out of stock
    • Tiny bit of muzzle climb while shooting

    Specs

    • Caliber: 5.56
    • Gas System: Mid-Length
    • Barrel Length: 16″
    • Overall Length: 32-1/2″ (Collapsed), 35-1/2″ (Extended)
    • Weight: 6.1lbs
    • Mounting System: M-LOK

    Daniel Defense has the quality, but what if you want to save a few hundred?

    BCM in my mind is the best bang-for-the-buck for top-tier stuff based on the several that my friends use and that I have extensively shot.

    BCM Recce 16 Rifle with MCMR Handguard

    Lately, supply has been limited.

    For my overall recommendation, I would get the 16″ with MCMR Handguard (M-LOK).

    We spent a lot of time with it and now have a full review here.

    Plus full video review too:

    However, more often than not the full guns are always out of stock.

    But have no fear…BCM has the uppers usually in-stock.

    BCM Uppers (T To B), 11.5, Pinned 14.5, 16
    BCM Uppers (T To B), 11.5, Pinned 14.5, 16″

    I would splurge for the MK2 upper which beefs up the upper receiver as well as the BFH barrel (barrel, forged, hammer). I’d personally keep the regular profile barrel unless you really want it light.

    BCM MK2 Upper Difference

    Once you’re in the upper page, definitely get their gold-standard BCG. For charging handle I like the ambi medium.

    I would also keep the flash hider instead of the comp unless you’re going for low recoil at the cost of a much louder gun.

    Pros

    • Affordable and wallet-friendly for budget buyers
    • Lots of options (barrel sizes, gas lengths, calibers, etc.)
    • Entry-level friendly — perfect for newbies

    Cons

    • Budget means some imperfections on the finish
    • Some caliber offerings can be a little picky on ammo, but the standard 5.56 eats just about everything

    Specs

    • Caliber: Varies (5.56, .300 BLK, etc.)
    • Gas System: Varies based on configuration
    • Barrel Length: Varies based on configuration (7.5″ to 20″ available)
    • Overall Length: Varies based on configuration
    • Weight: Varies based on configuration
    • Mounting System: M-LOK

    Balling on a budget? PSA makes everything in-house…turning raw materials into the finished AR-15 of your dreams. Find complete rifles (a lot of the time with free-floating rails) for around $600.

    Reputation is great too for rifles that simply work. Sometimes you’ll see some complaints about shipping times when there’s a large number of orders.

    I’ve finished testing three PSA rifles. Full review here.

    PSA 5.56 & .223 Wylde
    PSA 5.56 & .223 Wylde Builds

    And…now with a video review too!

    They have a lot of complete rifles…and they go in and out of stock frequently as people gobble them up. But whatever you’re looking for…16-inch FSB or 18-inch free-floating rail with Magpul MOE furniture? They’ve got the variant.

    For the truly budget-conscious, go for the Freedom Carbine…otherwise, I’d prefer a 16-inch mid-length with rails (are you getting tired of me saying that)?

    Depending on the market…you might be better off ordering a complete upper and complete lower separately. Something about an 11% tax on complete long guns. All you’ll have to do is connect them together with two pins. Easy peasy.

    If you decide to go this route, you’ll be able to have a bigger selection of furniture and rails (and the ability to get a sub $500 rifle). Check out Best AR-15 Uppers for my personal picks.

    Make sure to get one WITH bolt carrier group (BCG) and charging handle (CH).

    Pros

    • Premium features but at a decent price point
    • Great accuracy with practice ammo

    Cons

    • 20″ Sabre we tested struggled with steel cases
    • Slightly heavier than other AR-15s

    Specs

    • Caliber: 5.56 & .300 BLK (.223 Wydle uppers available)
    • Gas System: Varies based on configuration
    • Barrel Length: Varies based on configuration
    • Overall Length: Varies based on configuration
    • Weight: Varies based on configuration
    • Mounting System: M-LOK

    While we’re on the topic of PSA, the company recently upped its game with a new “premium” line of AR-15s called the Sabre.

    PSA Sabre shorty glamour
    PSA Sabre 13.7″

    And if you’re looking at the math for true best bang-for-the-buck AR-15 parts…this might be what you’re looking for…

    Compared to their normal line, the Sabre packs these upgrades:

    • Hammer-forged FN barrel
    • Microbest BCG with Sprinco extractor spring
    • Hiperfire RBT trigger & JP reduced power springs
    • Sabre compensator (pinned if you get the 13.7″ version)

    Plus, it just feels overall a nicer product in hand when shooting.

    PSA Sabre shoot tree right

    There’s also a 20″ variant as well as a standard 16″.

    However I’m a big fan of the 13.7″ pinned version because it gets you the shortest overall length without any SBR headaches. The only knock on this version is that it still has the high-pitched *tingggg* of effective flash hiders.

    But we go all over it (and you can hear it for yourself) in our complete review of the PSA Sabre line…and video.

    5. Smith & Wesson M&P 15 Sport III – Best Budget AR-15

    Pros

    • Decent entry level AR-15 at a nice price, budget-wise
    • Can be easily upgraded and customized
    • Has some updated features over its predecessor, the Sport II

    Cons

    • Not ambidextrous, sorry lefties
    • No QD

    Specs

    • Caliber: 5.56×45 mm
    • Barrel Length: 16″
    • Overall Length: 35″
    • Weight: 6.52lbs
    • Mounting System: M-LOK

    Smith & Wesson is another well-known name, albeit probably more known in the revolver and handgun world. Following up their very successful Sport II, the Sport III takes the helm as S&W’s go-to AR-15.

    S&W M&P 15 Sport III glamour 2

    Though the Sport III occupies a nice area budget wise, coming in sub $1K, it’s still a really nice AR-15 with decent features. However, lefties should be aware that there are no ambi controls.

    We did encounter an issue with the first rifle that Smith sent out to us, experiencing some feeding issues around the 150-200 round count mark. We sent that rifle back to Smith, got a new one, and had no issues whatsoever.

    S&W M&P 15 Sport III seated

    This isn’t a premium build, but if you’re dipping your toes into the AR-15 realm, it’s a decent place to start.

    Aero has its roots in years of aerospace manufacturing and makes almost everything in-house (a rarity nowadays).

    Make sure you don’t choose the M5 (different caliber) or Pistol (unless you’re building a pistol). M4E1 complete lowers are also great and come with upgraded buttstocks, grips, and better aesthetics on the lower (in my opinion).

    Tested and fielded by SOCOM for years…it’s probably the closest you’ll get without diving deep into a clone build.

    You can also get the upper and putting it on another lower receiver. However note your local and federal laws because it will become an SBR.

    It’s a little heavy with quadrails…but it’s nearly indestructible and has a perfect 10.3-inch barrel that keeps going all day for sub-300-yard engagements. And oh yea…it excels in CQB.

    Why the AR-15?

    BCM Recce 16 Rifle with MCMR Handguard
    BCM Recce 16 Rifle with MCMR Handguard

    The AR-15 is one of the most popular sporting rifles for many reasons. Here’s what we think are the top reasons:

    Used by the US Military

    Special Forces Beard Guy
    Special Forces Beard Guy

    Or rather, it looks like the M4s and M16s used by the US military.

    The civilian AR-15 is a semi-automatic rifle compared to the automatic/select fire capabilities of some of the military versions.

    That means one press of the trigger is a single PEW! instead of a fully automatic where a single press of the trigger will be a continuous stream of PEW! PEW! PEW! until you let go.

    The AR-15 is very light recoiling when chambered in its native 5.56x45mm round. And is also very ergonomic when compared to other popular rifles such as the AK-47.

    Check me out dumping 10 rounds on a PSA…

    Modular Design

    The AR-15 consists primarily of two large segments: the lower receiver…

    And the upper receiver, which can be swapped out in a matter of seconds.

    The AR-15 can fulfill roles such from a long-range precision rifle to close-quarters combat (CQB) carbine by just switching out the “upper” and mating it with the “lower.”

    Only the lower is the serialized firearm, so with one lower, you can have several uppers to fulfill any role without additional paperwork.

    The lower holds the trigger mechanism and for the most part, you can swap out the upper for even different calibers, from the .22LR to .300 BLK and even .50 Beowulf.

    There are also tons of aftermarket products to customize the look, feel, and performance of your AR-15 to match your personality and intended use.

    However, there’s a prevailing stigma (especially online) of putting too much possibly unnecessary stuff on your gun, and making you a “mall ninja” or being too “tacticool.”

    In my opinion…it’s your gun and your money, so do what you want to do as long as it’s still safe and legal. But…the above AR might have gone a little overboard!

    We’re also very obsessed…so here’s a (partial) selection of our upgraded uppers.

    AR-15 History

    Popular Rifle Calibers, Part I
    Popular Rifle Calibers, Part I

    Eugene Stoner developed the AR-15 as a lightweight 5.56x45mm version of the 7.62x51mm AR-10 while working at Armalite during the 1950s. The lighter bullet enabled infantrymen to carry more rounds. And that’s always a good thing!

    Naming Conventions

    M16 Vietnam
    M16 Vietnam

    In 1959, Armalite sold the AR-10 and AR-15 rights to Colt. The “AR” actually stands for “Armalite” and not the common misconception of “Assault Rifle.”

    After some tweaks, Colt introduced the M16 which was select-fire (automatic) and mostly had a 20-inch barrel.

    M4 Carbine
    M4 Carbine

    The M4 came about in the 90s and had a 14.5-inch barrel with a carbine gas system. Carbine just means that it has a shorter barrel than the rifle version and can either be pronounced “car-BEAN” or “car-BYNE,” but my preference is for the “bean” version.

    The AR-15 is the civilian semi-automatic version of the select fire M4. 1 press = 1 PEW!

    Colt owns the rights to “AR15” and “AR-15,” so most other manufacturers have slightly different names, but the general public still refers to the general pattern as AR-15’s.

    Now, one big question coming up…

    AR-15: To Build or To Buy?

    For a first AR-15, we would heavily suggest buying a complete rifle from a reputable manufacturer.

    Or at the very least, get a complete upper (Guide to Best Uppers) and build your own lower. It’s like Legos for big kids and you can see our recs at Best AR-15 Lowers.

    Couple AR Lowers
    Couple AR Lowers

    Now there are also options to simply get a complete upper AND a complete lower. This way saves some money too since companies are charged an 11% tax on complete firearms.

    Buying complete eliminates a lot of possible headaches by having a solid warranty behind your gun. Plus, if you’re just starting off, you probably don’t know what you like/want, so I recommend just going with a standard configuration.

    A factory gun doesn’t cost that much more than building your own (and nowadays it’s likely less), and you’ll get a much better resale value if you ever decide to part ways (or upgrade).

    AR-15 Build Your Own Kit
    AR-15 Build Your Own Kit

    However, there’s something very satisfying about building your own “franken-gun” or “M4-gery,” but we recommend doing it for a 2nd or 3rd AR-15. It’s not terribly difficult and you’ll get to choose every component in your gun.

    But we think you’ll make better decisions after spending time with a factory gun first.

    Next, we dive into the various parts of the AR-15 before putting it all together and recommending specific combinations based on your intended use.

    All About AR Barrels

    We begin the breakdown of the AR-15 system by covering the various characteristics of barrels (the thing that bullets come out of).

    Now the real fun is going to start!

    Barrel Chambering

    AR-15 Chamber
    AR-15 Chamber

    The barrel chamber means the part of the barrel where the cartridge sits before firing (ie, what ammo it can shoot).

    Since this is a beginners’ guide, we’ll focus on the most common 5.56x45mm NATO and .223 Remington. There are tons of other chamberings from .22LR to .50 Beowulf, and a slew of new .30 caliber offerings.

    The 5.56 is the more common choice compared to .223 since it gives “looser” tolerances and can withstand the higher pressures of the 5.56 round.

    Here are some general safety guidelines for using different cartridges in different barrels:

    • With a 5.56 barrel, you can shoot BOTH 5.56 and .223
    • With a .223 barrel, you can ONLY shoot .223
    • Hybrid chambers such as Wylde are for specific precision purposes but can shoot both

    Barrel Length: Long & Strong

    AR-15 Different Barrel Lengths
    AR-15 Different Barrel Lengths

    Federal law states that the minimum barrel length of a rifle must be at least 16-inches. This includes muzzle devices, such as flash hiders, muzzle brakes, or compensators. However, if the device is to be included in the length, it must be permanently attached.

    Tested Muzzle Brakes
    Tested Muzzle Brakes

    For example, you can have a 14.5-inch barrel and permanently pin/weld a muzzle device to make it over 16-inches to make it compliant. Please note, there are some state/local laws that might govern the types of devices allowed, and even having a 14.5-inch barrel might be illegal without appropriate paperwork.

    Therefore, we recommend beginners get at least a 16-inch barrel so they can switch out muzzle devices to their liking. Most common lengths include 16-, 18- and 20-inches.

    So which one do you choose?

    AR-15 Barrel Length Velocity, SA Defense
    AR-15 Barrel Length Velocity, SA Defense

    Having a longer barrel doesn’t necessarily mean more accuracy. You can get plenty of accuracy out of 16-inches since it is shorter and therefore stiffer and less susceptible to barrel whip (movement of the barrel during shooting).

    However, a longer barrel gives you higher velocity since there’s more room for all the powder to burn. And faster-moving bullets give the environment (gravity and wind) less time to affect the trajectory of the bullet.

    PSA .223 Wylde 18"
    PSA .223 Wylde 18″ Barrel

    The average 16-inch barrel is good for up to 400-yards, but after 300-yards, the standard 55-grain projectile becomes more susceptible to environmental factors. 

    For longer distance, you would want a heavier and longer projectile such as 62gr, 77gr, or 80gr bullets.

    Assorted 5.56 Rounds (XM193, XM855, Gold Medal 69gr)
    Assorted 5.56 Rounds (XM193, XM855, Gold Medal 69gr)

    Lastly, there’s also the issue of portability…shorter barrels are easier to move and weigh less.

    So many things to think about!

    Barrel Twist Rate

    Barrel Rifling, Criterion Barrels
    Barrel Rifling, Criterion Barrels

    Another number you’ll see when looking at barrels is the twist rate of the rifling.

    This is denoted as 1 x number (1×9) which means “one twist per 9 inches”. In general, the longer a projectile, the faster the twist is needed (a smaller number in the twist since that means one turn happens in a shorter length).

    Below is a great chart to show you the ideal bullet weight for the twist of a barrel.

    Bullet Weight vs Twist, Shooters Log
    Ideal Bullet Weight for Twist, Shooters Log

    The most common AR-15 twist rate is 1:9 since 55gr is the most commercially available while the most common mil-spec twist is 1:7 since they need to stabilize longer/heavier tracer rounds.

    Barrel Material

    There are a lot of numbers and scary sounding words out there when related to barrel material, and we’ve done our best to simplify it:

    • 4150: Steel used in mil-spec barrels
    • 4140: Steel with 10% less carbon than 4150
    • Chrome Molybdenum Vanadium, Chrome Moly, or CMV: Same as 4140
    • Stainless Steel: More accurate but shorter lifespan
    PSA .223 Wylde 18"
    PSA .223 Wylde 18″ with Stainless Barrel

    For the average shooter just go with the 4140/CMV. Unless you’re firing full-auto a lot, you probably would not reap any benefit from 4150. Except for a lighter wallet…but that probably doesn’t count as a benefit.

    PSA Barrel Coatings
    Coatings/Materials (L to R: Nitride, Nitride, Stainless Steel, Phosphate)

    Barrel Lining

    Chrome Lined Barrels
    Chrome Lined Barrels
    • Chrome Lined: Coating that makes your barrel last longer at the price of a slight decrease in accuracy. You’ll see a gray ring around each end.
    • Ferritic Nitrocarburizing (FNC): Also known as Tennifer, Melonite, or Nitride. Treats the surface of the barrel instead of a coating for possibly better accuracy but with additional cost.
    • None: No coating.
    Criterion Barrels, Different Coatings
    Criterion Barrels, Different Coatings (Top to Bottom: Stainless, Chrome, Nitride)

    Real round counts will differ based on a lot of factors (heat, environment, your definition of “accuracy,” etc), but you can expect around 10-20k before you have to re-barrel.

    You still there?

    Barrel Testing

    Good, here’s some more acronyms manufacturers will throw at you.

    MP HP Tested Barrel
    MP HP Tested Barrel
    • MP: Magnetic Particle tested, magnetizing the barrel and using fine iron particles to detect cracks/defects
    • HP: High Pressure tested
    • None: No testing. You get what you pay for.

    You might run into the use of “batch tested” which really doesn’t mean much. The manufacturer may test 1 out of 10 barrels or 1 out of 100K barrels. For a home defense rifle, we recommend getting a barrel that is both MP & HP tested.

    You know…just in case.

    Barrel Forging

    • Cold, Hammer, Forged (CHF): Process that creates a more durable barrel
    • Barrel, Forged, Hammer (BFH): Same as CHF
    • None: No extra process

    CFH and BFH reduce accuracy a little but you gain a much more durable barrel. If you plan on shooting thousands of rounds a year, it might be worth the extra cost and push you towards a 20k+ round count.

    Barrel Contours

    Shape and thickness of the barrel will have a decent effect on the overall weight. And if you haven’t seen this quote yet on forums…“ounces equal pounds and pounds equals pain.”

    AR-15 Barrel Profiles
    AR-15 Barrel Profiles
    • CAR (Colt Automatic Rifle): Just a specific family of AR-15/M-16 rifles from the 70’s. Now just a general term for carbine-length rifles before the advent of the M4.
    • Heavy (Bull): Stiffer and heavier but more accurate. Can take a lot of heat before shooting groups start to suffer. Normally used for precision builds. .936-inches in diameter.
    • Medium (Government or M4): All around balance. M4 contour has a cutout for grenade launchers. .750-inches in diameter.
    • Light/Pencil: Lighter but more susceptible to heat from rapid firing. .625-inches in diameter.

    For the average plinker, Medium or Light barrel contours will work great.

    And to make it more fun…some manufacturers also have their own versions too.

    Barrel Feed Ramps

    This is an integral part of the upper receiver and you want it to be a proper match with your barrel.

    M4 Feedramps, AR15Barrels
    M4 Feedramps, AR15Barrels

    The jury is still out whether or not they help reliability, but the main thing is to match up the ramps with your receiver. If you’re buying from the factory, this should not be a problem. But you still might want to check.

    AR-15 Gas Systems

    Now that you’re a pro with AR-15 barrels, we’ll go into the gas system.

    There are two major types, Direct Impingement (DI) and Piston. DI is the original design while piston only really became popular within the last few years.

    Direct Impingement vs Piston

    An AR-15 works by directing the hot gas behind the bullet into the gas tube (where the triangular front sight block is above) which then uses the gas to either move a piston or send it directly back (direct impingement).

    Faxon 16" Gunner 5.56 Barrel
    Faxon 16″ Gunner 5.56 Barrel with DI Gas System

    When the force is applied, it makes the bolt unlock, move back, expel the spent casing, and strip a new cartridge into the chamber.

    The vast majority of ARs are direct impingement instead of pistons.

    Direct Impingement

    Pros of Piston:

    • Cleaner since dirty gas is vented away
    • Should be more reliable in bad environments (water, dust, etc)

    Cons of Piston:

    • Costs more than traditional DI system
    • Weighs more and puts weight in front (although getting better each year)
    • Proprietary parts unique to each manufacturer
    • Less accurate

    Unless you’re needing to shoot coming out of water or in very dusty environments with limited ability to clean, a direct impingement system will work fine. If that’s you…here’s our review of the Best AR-15 Piston Uppers.

    With proper maintenance, a DI AR-15 is a very reliable weapon and what the military uses.

    Direct Impingement Gas System Lengths

    The gas system length refers to the distance to the gas hole, or where the triangular “front site base” or FSB sits on each barrel above.

    The rifle-length gas system is traditionally used for 18-inch or longer barrels, but there is the oddball “Dissipator” model which has a rifle length system on a 16-inch barrel.

    AR-15 Gas Systems Barrel Lengths
    AR-15 Gas Systems Barrel Lengths

    For 16-inch barrels, the primary choice is between carbine and mid-length gas systems.

    AR-15 Gas System Lengths
    AR-15 Gas System Lengths

    We believe the mid-length has the advantage since it allows a longer sight radius if using a front sight base (which doubles as the front sight). 

    It also gives you more possible handguard/rail space since the handguard goes from the upper receiver to the front sight base.

    PSA Valkyrie vs 5.56 Barrel
    Two Different Length DI Gas Systems

    It should also theoretically offer a smoother/softer shooting rifle since the increased distance will allow gas pressure to lower before going back into the rifle.

    But, this is influenced by a lot of other factors including gas port size, buffer, and spring combinations.

    Gas Blocks

    For the majority of this article, you’ve been seeing the front sight base (FSB) style gas block which combines the front sight with the gas block.

    PSA FSB vs Free-Floating
    PSA FSB vs Free-Floating

    For years I’ve been recommending this style for beginners for the ease of already having a front sight, robustness (the FSB is pinned to the barrel), and cost-efficiency of a non-free-floating barrel.

    You can also choose to grind down the FSB to fit a free-floating barrel later.

    BCM in the Desert
    BCM in the Desert

    BUT…there are many AR-15s that now offer low-profile gas blocks that enable a factory install of a free-floating barrel.

    Some of these gas blocks are also adjustable so you can choose just the right amount of gas to make your rifle/ammo combination run smoothly without unnecessary recoil.

    If you know you’ll want to add stuff to your AR…skip the headache of grinding down the FSB or getting a new upper…and start off with a free-float handguard.

    Handguards

    Front sight blocks almost always force you to utilize non-free-floating handguards.

    PSA 16" Nitride with FSB
    PSA 16″ Nitride with FSB

    This means that the two-piece handguard touches the barrel at the FSB and can add some inconsistency in force that makes it slightly less accurate.

    S&W M&P Sport II smoky
    S&W M&P Sport II Smoky

    But for non-competitive shooters, you’ll be fine with a non-free-float. There are some aluminum variations, but most are polymer which still work great and are more affordable.

    The above Magpul MOE Handguards for Carbine or Mid-Length still allow you to add Picatinny rails on the slots to attach accessories or use their new M-LOK attachment system directly.

    Picatinny rails were the gold standard of rail attachments and look like raised rectangles. Below is an example of a “quad-rail” since there are Picatinny rails on all four sides. 

    FN 15 quad rail
    FN 15 Quad Rail

    The big con was its weight.

    And of course, you’ve seen the free-floating handguards for low-profile gas blocks. This allows more consistency in your shots since there’s nothing touching the barrel along the handguard. Those usually cost $100 to $200 more but allow tons of rail space.

    Now for some serious stuff…

    AR-15 Bolt Carrier Group (BCG)

    How the BCG Works

    Essentially the engine that runs the AR-15. The bolt is housed within the bolt carrier and together they make up the bolt carrier group (BCG).

    Best AR-15 BCGs
    Best AR-15 BCGs

    It moves back when you pull the charging handle back.

    Charging Handle and BCG Labeled
    Charging Handle and BCG Labeled

    And when you let go of the charging handle, the BCG moves forward, strips a round out of the magazine, and puts a round into the chamber.

    When you pull the trigger, the hammer releases and strikes the back of the firing pin which is also in the BCG.

    The firing pin hits the cartridge’s primer which sparks the gunpowder and sends the bullet down the barrel. Then the gas system comes into play.

    Watch it below:

    Semi-Auto vs Full-Auto BCG

    The BCG comes in semi-auto (SA) and full-auto (FA) varieties. Having a full-auto BCG does not instantly make your gun automatic. Normally it is used to slow down the cycling rate due to its increased mass (see the right ends of the BCGs below).

    Note that they should be overall the same size but the bottom FA is shrunk in the picture.

    AR-15 Semi-Auto vs Full-Auto BCG
    AR-15 Semi-Auto vs Full-Auto BCG

    The full-auto has a shroud to protect the firing pin from hitting the hammer during re-cocking. You can see the right-most BCG has more of the firing pin exposed and less weight on the bottom, making it a semi-auto version.

    BCG Shroud, AR15
    BCG Shroud, AR15

    It doesn’t really matter which one you get, but most higher-end manufacturers will put in the FA BCG. Most guns are over-gassed so they can run a larger variety of ammunition, so the additional mass and firing pin protection are advantageous.

    What do I mean by over-gassed?

    In an ideal world, the gas block would send back the bare minimum amount of gas to move the BCG back so it can eject the spent casing and strip another round.

    BCM M16 BCG
    BCM M16 BCG

    However, there’s the problem of weaker ammo which would produce less gas, and also the crud that accumulates and can slow everything down.

    Therefore, manufacturers usually let a much larger amount of gas cycle through to brute force through the issues. A heavier BCG and shrouded pin minimize the negative effects of a lot of gas.

    There are also lighter BCGs for competition guns…but don’t worry about that for now! Unless you want to here.

    BCG Coatings

    One of the newest crazes is to have coated BCG’s that are supposed to make them easier to clean, require less lubrication, and run longer between cleanings.

    Buffer Tubes, Triggers, & More

    Mil-Spec vs Commercial Buffer Tubes

    This comes up more when you are building a lower from scratch. Just go with Mil-Spec instead of Commercial since it is stronger. Also, make sure to match up the carbine/rifle lengths according to your barrel.

    Triggers

    I’d stick with the standard Mil-Spec trigger initially. It may be a little gritty at first but will become better with use.

    I like it for its reliability.

    Mil-Spec Trigger
    Mil-Spec Trigger

    More precision rifles will use aftermarket single-stage or two-stage triggers.

    However, I will say that the first upgrade I would do to a rifle would be upgrading the trigger. Just stick with the stock one first…if only so you can fully appreciate an upgraded one!

    AR-15 Intended Purposes

    We’ll cover the four main flavors, each with its own pros and cons.

    M4gery

    Typical AR-15

    Known lovingly as the “M4-gery” (M4 + Forgery), this is the most common AR-15 type which seeks to mimic the M4 military carbine.

    PSA 16" Nitride with FSB
    PSA 16″ Nitride with FSB

    While the M4 has a 14.5-inch barrel with a carbine length gas system, most AR-15s of this variant will use a 16-inch barrel and a mix of carbine and mid-length gas systems. 

    Most will have collapsible buttstocks so you can adjust your length of pull and eye relief.

    M4gery’s span many varieties.

    Precision/Varmint/SPR/DMR

    AR-15 Varmint
    AR-15 Varmint

    Varmint/precision builds likely will have an 18- or 20-inch barrel of the heavy contour variety for extra stability and velocity. The twist rates and materials may also change for more accurate combinations (1×8 or 1×7 and non-chrome-line or stainless steel).

    Oh…and get ready for some more acronyms such as Special Purpose Rifle (SPR) and Designated Marksman Rifle (DMR). Basically…longer barrel.

    Precision AR-15s will also most likely have free-floated handguards and heavier buttstocks. You’ll want to add a scope and probably a bipod too. Get ready for a much heavier rifle!

    SBR/Pistol Builds

    Daniel Defense MK18
    Daniel Defense MK18 SBR

    We won’t be covering much of them in this guide, but if you do go this route, be extra sure of your state/local laws since you’ll be going with sub-16-inch barrels. Traditionally this is known as a Short Barreled Rifle (SBR) which requires paperwork and a tax stamp.

    Aero AR-15 10.5" Pistol
    Aero AR-15 10.5″ Pistol

    And for a few short years there were “pistol braces” that allowed for sub-16″ barrels without applying for an SBR. However as of June 1, 2023 these are no longer valid…but there’s several injunctions in the works. Check out the current status of Pistol Braces and the ATF.

    Daniel Defense MK18
    Daniel Defense MK18 Pistol Brace

    Both make the tradeoff of a shorter, lighter, and easier-to-handle weapon. But the drawbacks include much-decreased velocity and increased muzzle blast (people around will HATE you). 

    SBRs and AR pistols are best suited for under 100 yards.

    Competition Builds (3-Gun)

    JP15 3-Gun Rifle
    JP15 3-Gun Rifle

    Competition guns are specifically tailored race rifles for 3-Gun (rifle, pistol, & shotgun) or other competitions.

    Normally you’ll see longer barrels and gas systems coupled with big brakes/compensators to reduce recoil and enable faster follow-up shots. Almost everything else in the system is customized to the shooter.

    Pistol Caliber Carbines

    Another new entry to the field is pistol caliber carbines (PCC). They are also known as AR-9s and I’m pretty sure you can guess what they are!

    Featureless Builds

    It brings me great sadness to have to add this for 2017+.

    Resurgent Arms Featureless Grip, Left
    Resurgent Arms Featureless Grip

    But featureless rifles make it legal for residents of CA and NY (and probably more) to own AR-15 style firearms with accessible magazine releases.

    The biggest differences you’ll see are no pistol grip, non-adjustable buttstock, and no flash hider. For more, check out our Featureless Rifles page.

    Best AR-15 Manufacturers

    Love it or hate it…people really want these groupings. These are my personal point of view and fluctuate through the years as I gain more experience.

    Drumroll, please…

    Top Tier AR-15 Manufacturers

    These are our perceived top-quality manufacturers who don’t cut corners and can produce near 100% reliable guns (or they have an awesome marketing budget).

    If you’re looking for the best service grade (mil-spec) AR for self or home defense, we recommend going with one of these top-tier companies that stand behind their product.

    Mid Tier Manufacturers

    These are great guns that might start out range plinking guns until they’ve proven themselves. We recommend putting at least 1,000 rounds through with varying conditions, ammo, and magazines before you trust a gun with your life.

    The below is not an exhaustive list, especially with all the builders out there.

    Budget Manufacturers

    Nothing wrong with these guns either, they are great starter ARs because of their affordability and are perfectly capable of being reliable. Just test them out first.

    Price

    For a top tier, expect to pay $1,300 to $2,000 for a complete rifle, while mid-tiers can start around $900. Intro AR-15s are attainable for around $500 now thanks to Palmetto State Armory.

    Remember, you’re paying for the quality of materials, quality control, and R&D. Ok…and probably marketing too.

    Featureless Rifles

    For the folks in CA and NY. 

    There has been a lot more activity here (Springfield and LWRC) but I’m holding off on adding everything until I can review them in hand.

    The easiest is to buy a featureless at your local gun store or turn your current one following our Featureless Guide.

    Building?

    If you really want to build your lower…

    All AR-15 Lower Receiver Parts
    All AR-15 Lower Receiver Parts

    I’d recommend looking at our Best Lower Receivers article and then following How to Build a Lower Receiver.

    But my advice is still…buy a complete rifle! Or at least two complete halves.

        This is why the gun community suckkkkkks. Especially for AR15s. It's the world's largest cesspool of low IQ keyboard warriors who absolutely must ensure that everyone knows they are THE expert on all things bang and anyone who thinks otherwise is a moron. This guy put a list together based on his own opinions he's not attacking anyone's choice. Read down the comments and all you get is crap slinging and long rants about the same old bs. It's the same everywhere. No one cares what Reddit told you. No one cares what your favorite guntuber thinks. No one cares how popular you are on ARFCOM. This should be a community of respect and comradery instead it's just cringe idiots everywhere arguing about nothing. It's getting old AF.

      I have two Anderson ARs, one a factory build and one customized. They cost about $500 and $750, respectively. I’ve fired well over 1,000 rounds through each without an issue. I’d highly recommend Anderson for the budget option.

      Actually, I consider my KAC and my LMT to be top tier. My DDs and BCMs are more upper-mid tier.
      Down the list, for a low tier, I have a PSA CHF/Premier level that is some of their best stuff. All I did to that was put a Rave 140 trigger in it, and at 3 lbs, it's a great weapon.

      For a quick upper/lower combo, I have an 11.5" Aero S One with a nice PSA SBA3 lower, with a Timney Impact trigger. That's all I need in a pistol, something that I'm confident will go BANG all the time. Also, 11.5" is the shortest barrel that has good velocity and doesn't punish the moving parts.

      Well, unless you burn the big bucks for a Q LLC Boombox, Honey Badger, or similar quality.
      But $3-5K? Ouch.

      Why no mention Anderson AR15 Utility Pro. I think this is a great first AR gun to learn from. Yes, I know you think it’s cheaply made, but if you break it down it does have quality parts on it. I just bought one with a lot of videos, reviews and You Tube channels range shooting. The last one I saw, they shot 1,000 rounds through it on automatic. It did not break down, of course the barrel heated up, no failures. All different shows of different experience stated they found a new AR under $550. I paid $429 at Sportsman Warehouse. I can’t wait to shooting it. Check out the shows on You Tube, they show all different AR platforms and pistol and rifle. There are 4-5 shows on Anderson AR15 from cleaning to adding parts to shooting. Watch the shows.

      That article, Eric, is the best I've read in a very long time on the AR style rifles. Concise and to the point. Videos were informative to watch. My first AR was a Colt LE. Only changes/adaptations were the butt stock (Hogue), a straight pistol grip (Bravo Company), a vertical grip that contained a internal bipod, and an Aimpoint red dot. My next AR was the Springfield Armory Saint. Same mods with exception of the red dot, a Sig Romeo5 and Juliet 3X magnifier. These rifles used on the job as a police officer. Uncle Sam provided basic training with the M16 and M16/M203 way back in the day. Keep up the great articles! I don't care if your picks don't include mine as the quality of the information is what is important and greatly appreciated.

      I applaud your choice to say car-BINE. I have a DVD copy of a 1952 movie called “Carbine” Williams (the…inventor?…of the genre, or did he just make it work right?), starring Jimmy Stewart as The Man. Since Carbine Williams himself was the technical consultant on the movie and they call him car-BINE throughout I’m going to have to assume that car-BINE is the correct pronunciation of his name. Since car-BEAN is in such common use I guess this will never be corrected.

      When you talk about the BEST AR, you left out LWRC, who make the finest and widest range of ARs around. They pioneered Piston action ARs. I also must disagree with what you have said regarding the piston system being less accurate: I find my LWRC to be very accurate and above all easy to clean!!! I was a grunt with M16A1 and the damn thing was always jamming because of carbon fouling. After firing that POS it took an average of 2 HOURS or more before my soldiers could clean them well enough to be accep-0table for return to the arms room. That's why the Army is no going to the XM-7, a piston operated, specialized 6.8 round. Anyone who has to depend on the DI weapons in combat will tell absolute tales of horror when the damn thing failed because it was dirty. Any comments from other combat Vets?

      You mentioned the Aero Precision PC Caliber Carbine for $314. I thought, I might want one of those. So I clicked on the link, and all I found was a bunch of parts, no complete rifle. Then as I scrolled down through the article, I saw all of the parts that are needed for a complete AR-15. There is no way I would even attempt to buy all the correct parts and then put it together myself!

        I love the Constitution. It guarantees my right to freedom . The gun culture in America has brought that into danger. We need safe storage laws. We need to stop selling modern infantry rifles meant for killing people on the battlefield quickly and in large numbers to anyone with $500. We need safety training requirements before people buy weapons. We need to enable the TAF so it can find and prosecute America's thriving gun traffickers. We need safe storage. We need to stop selling semi auto pistol people killers to anybody with a few hundred bucks. In short, we need a responsible gun culture. And we do not have that. Which is why, America has the WORST per capita gun violence problem on earth. By a large margin. The social media gamers and ignoramus MAGAs on this site keep denying it. I don't argue with liars. I simply state the facts. Worst per capita gun violence rate in the world AND the most guns per capita in the world. They're a correlation there. We need gun safety legislation and responsible understanding of what modern infantry rifles are. Pew Pew ??? How cite a way to describe a 5.56 round that can blow a child head apart.

          William Fraser:

          Some of the things you have listed would probably be good, except for the fact that there are many in the American government that use "common sense gun laws" as cover to totally disarm the people. New York City is a prime example. The founders knew that, and that's why they said that our right to own and carry guns "shall not be infringed".

          Your post above illustrates what I am talking about - you want to eliminate semi-automatic pistols that cost a few hundred bucks. By doing so, you would be eliminating the most basic handguns. In other words, you aren't talking about "responsible gun ownership", but rather taking away all guns from all private citizens.

          All of the steps you have listed in your post show that you aren't interested in "common sense gun laws", but rather the total disarming of the American people.

          The United States has the only constitution in the world that guarantees an unrestricted right to own and carry guns. Why would the founders put such a thing in the original constitution? Because they really did believe in a government of, by, and for the people. They trusted the regular folks to manage their own affairs with as little government interference as possible.

          Also, it's a lot more difficult for a dictatorship to take over when so many private citizens are armed. That's what they meant by "well-regulated militia" - a militia was a group of private citizens WHO OWNED GUNS, who would show up as needed, fight WITH THEIR OWN GUNS, then go back home WITH THEIR OWN GUNS. A posse in the Old West was an example of a well-regulated militia, because it was run by the sheriff, but it was private citizens who were armed WITH THEIR OWN GUNS. And once they caught the crook, they went home WITH THEIR OWN GUNS. They never handed them over to the sheriff.

I believe a companies actions should be just as much accounted for as quality when rating weapon manufacturers!

      As an avid AR-15 enthusiast, I can vouch for the rifles listed here. The customization options for AR-15s are almost endless, and it's important to choose one that fits your intended use. Personally, I prefer the versatility of the "Jack-of-All-Trades" option mentioned – having a balance between accuracy, weight, and accessory compatibility is key.

      Again. America has the WOSR per capita gun violence rate in the world. Your comment reflects the fact that you are so propagandized by the gun industry's partner, the NRA, that you don't care that all of us. are more likely to. be gunned down in the USA than any nation on earth. I'm a USMC infantry officer fro. the Vietnam era, a championship shooter and a qualified range officer. Again. America has the worst per capita gun violence rate on earth./ Easy access to firearms is the cause. The 2nd Amendment guarantees our states can have armed militias. They do. The gun owners are NOT a well organized militia and private militias are illegal under the US Constitution. Your attitude and your insistence simply guarantee more gun violence in America. So. you may not care about America's gun violence problem ,b ut Ido. And , by the way, I never "debate" with p[eople incapable of logic who simply rep[eat falsehoods. This isn't a "debate". You are opposed to gun safety ANDyou support policies enabled by the NRA that guarantee that the gun violence epidemic will continue in America. congratulations clown.

        The right of the people shall not be infringed. That means everybody, not just the militia. The US Supreme Court has settled this several times. People means everybody. The reason there is so much gun violence is because the liberals have decided to defund law enforcement and turn criminals back out on the street which makes no penalty for wrong doing. You are the clown, and there is no debate about that!

      "Guns everywhere" with minimal safety laws is why America has the worst per capita gun violence rate on earth. And you can insult me until you are blue in the face but it will not alter this fact . Imagine a gun range with no safety rules. Does that sound safe to you ?? If it does then we don't need to discuss this further. Because invariably, the only feedback I get to gun safety posts is denial, threats and anger.

          Once again. No facts. No logic. America has the worst per capita gun violence rate on earth. America has an unsafe, gun culture and little law enforcement of gun trafficking due to NRA anti ATF GOP legislation . Such as, the ATF is prohibited from using any computerized gun serial # registries. Thats illegal thanks to the NRA. So it shouldn't be surprising that the ATF rarely if ever is able to prosecute gun traffickers. Say thank you to the NRA for that.. Cheers.

The ATF barely makes half a dozen cases against gun trafficking every year. So no worries . You're safe. Well, as safe as anyone can be in a nation with the HIGHEST BY FAR gun violence rate in the world. And what have you done to democratically encourage gun safety legislation that can reduce the gun violence ??????Nothing. Thanks a lot. My kids are less safe. And so are yours. And everyone else's ....And go by the way of the worst 17 mass murders in recent history in the US, 11 were committed with AR 15s. And thats because it is a modern infantry style rifle designed t kill as many enemy combatants on the battlefield as fast as you can shoot. Some "Sport" rifle. Keep making believe it's not a military rifle. My Marines carried it in 1973. And it went into use in the US military in 1966. Just a little history for the little "pew' "pew" LETHAL infantry rifle popular around the world.

I'm not sure what "SPECIAL STANDING" BEING IN THE SERVICE - YOU THINK GRANTS YOU! iT IS WONDERFUL TO SERVE YOUR COUNTRY, BUT SORRY TO INFORM YOU it doesn't make special, and it sure as hell doesn't make you smater, YOUR COMMENTS ATTEST TO THAT
