Red dots on pistols and rifles have become the it thing in the gun world…with good reason.
These handy devices can improve target acquisition and make the shooting experience more fun and enjoyable. But not all red dots are made equal..in fact; some are made green.
Green dots have slowly risen in popularity over the years as more and more people are finding they’re pretty easy to use.
But the colorful world of red dots can be confusing and overwhelming. With so many options, you might be asking yourself what do I choose?
No worries, we’re here to help. We have our resident astigmatism-plagued shooter here to walk you through the difference between red and green dots and which green dots are actually worth your time and money.
So, keep reading!

Red Dots vs. Green Dots
To understand red vs green, let’s get into some science.
First, it’s important to know that light is measured in wavelengths. The distance between the peaks is called nanometers. Those distances correlate to a number, and every color has a number.
Since we’re talking about red vs green, we’ll keep to those colors. So, red is 625nm-740nm, while green is 520nm-565nm.
The long and medium cones in human eyes peak at 560nm and 530nm. As you can see in the image above, both are in the green area.
Yes, most of us can see red (sorry colorblind, pals), but we tend to be able to see more green — both in terms of shades and vibrance and also depth. In fact, the average person can see 30x as much green as any other color.
So, our brains are wired to pick this color up faster and process it more easily.
Decades of trial and error experimentation have proven that green delivers the best depth perception, which is why you’ll see it in night vision goggles and sights.
Our eyes are basically designed to see more shades of this color, making it ideal for stealthy nighttime optics.
But Why Aren’t All Dots Green, Then?
You may be wondering why green isn’t more prevalent if our eyes do better with it…
Science aside, it depends a lot on the person behind the optic.
Everyone’s vision is a little different. You might do better with green, but your buddy’s eyes might work with red better.
Generally speaking, though, if you’re older, have poor eyesight, or suffer from astigmatism — a green dot might work better for you.
Personal factors aside, battery and close are other reasons these aren’t as popular.
It takes a lot more power to run a green dot than it does a red. With a lot of consumers wanting long battery life and since most can see red dots fairly well, optics companies tend to produce red dots more.
Also, the price of green dots is a little more than their red dot counterparts.
Now that we’ve talked about red vs. green dots, let’s run through some of our top recommendations…
5 Best Green Dot Optics
1. Holosun HE510C-GR Elite
Holosun is known for making affordable optics of good quality, and the Holosun HE510C-GR Elite is no exception.
This feature-rich model offers three reticle settings, a Titanium-alloy hood, solar battery assist, and Shake Awake.
It also sports an internal battery tray which means you can replace batteries and not have to re-zero. That alone is a win.
Speaking of battery life, the HE510C brings 50,000 hours of max battery life. That comes out to over 5 years or so. Not bad!
In addition to an impressive battery life, this optic has a 32mmx24mm lens, offering plenty of visibility to see your target.
The only thing you might want to watch out for is that exposed emitter. IMud, debris, or other junk could block it. That hasn’t happened to us yet, but it’s worth mentioning.
Overall, we really dig this model and its durability. It’s a good blend of price and features.

2. Trijicon MRO
We can’t talk optics and not mention one of the biggest names in the game…Trijicon.
This company is known for producing durable, reliable, and high-quality optics, and the MRO is no exception.
Though its features err on the side of basic, this reflex sight really earns its keep in how bomb-proof it is. In terms of what it has to offer, it comes with a 25mm lens, great glass quality, and eight brightness levels.
Battery life for the MRO sits at around a year.
Additionally, this optic comes with two night vision compatibility settings, so if night vision is your jam…look no future.
The only downside to the MRO is the price. Edging closer to $500, it is a little pricey but it’s well worth the coin.

3. Holosun HE507K-GR X2
The Holosun HE507K-GR X2 is a great green dot perfect for your carry pistol.
The 507K comes with multiple reticle settings and features solar battery assist, Shake Awake, and 50,000-hour battery life.
Additionally, the HE507K-GR X2 brings Lock Mode technology. This mode locks the buttons and prevents users from accidentally changing settings. This is a great way to ensure your settings don’t get messed with in your range bag.
This Holosun also sports a side-mounted battery tray, so you don’t have to dismantle the whole thing to swap batteries. I really like this feature because, let’s face it, it’s a hassle to remove your red dot just for a battery change.
Overall, the HE507K-GR X2 is a reliable and affordable option for those looking for a good pistol optic.

4. Sig Sauer MSR Green Dot
If you’re looking for an option to test the waters, then we highly recommend the Sig Sauer MSR.
This optic is super budget friendly…like around $100. It’s a great way to dip your toes in the green dot pool and see if this option is the right one for you.
The MSR ops for a 20,000-hour battery life as well as two night vision modes. It also comes with lens covers and a top-mounted battery compartment. We already talked about the convenience of battery compartments that are easy to access and don’t require removing the whole optic.
To top it off, the MSR comes with a mount, so you’re ready to rock and roll with it straight out of the box.
To put it simply, we think this is one of the best budget green dots on the market.

5. EOTech XPS2-0GRN
Want a holographic style but need that green dot? The EOTech XPS2-0GRN is the way to go.
This optic is like most other EOTech designs in that it’s built to be durable. Seriously, these are pretty bomb-proof.
We have even shattered the glass of an EOTech optic before, in the name of science, and it still ran.
That’s about as good as it gets, folks.
The dot itself is a nice, bright green that appears very crisp — even when magnified.
Battery life on this model is less than previous optics mentioned, sitting at around 600 hours BUT holographic sights pull some serious power.
So, it’s not a surprise, and for a holographic and green dot, 600 hours is still pretty good.

6. Viridian RFX35
Viridian has a long-standing name in the green dot world and the RFX35 is a great addition to their lineup. The 6061 aluminum housing looks very similar to the Trijicon SRO and the footprint is the same as well.
With that design, the shooter gets a large window, allowing for quick access and sight picture. The glass is also multi-coated to aid with visual clarity.
The RFX35 has a 3 MOA green dot and features instant on when moved. The buttons allow you to manually adjust between 8 daytime and 2 night vision settings.
Of course, the green dot is IPX6 waterproof, and it is powered by a 2032 battery. Combining the instant on with a 2-minute back to sleep cycle, the RFX35 gets approximately 30,000 hours of use.
We tested this optic out with the Arex Delta Gen 2 and found it to be daylight bright, and very durable. Despite repeated efforts, we couldn’t beat the awake feature while drawing!

Final Thoughts
Green dots are a great way to get into optics if traditional red dots just don’t work for your eyes.
Not to mention, for some, they can improve target acquisition times, offer better contrast, and an overall sharper reticle.
While battery life and the larger price tag may be a limiter for some, we think these are solid models for those looking to jump into the green dot game.

Anyone else having trouble seeing green dots in the country in the spring/summer when the corn and soybeans are green?
Anyone know what happened to the HE512T-GR green dot? Cannot find anywhere
Love the Holosun offerings in this review. I have both, one on my HK SP5 and the other on my Sig X-macro. Fantastic products and can wholeheartedly recommend.
I just purchased the red and green dot Sig Sauer Romeo MSR and I am liking the green color better. I don't have astigmatism but I can pick up the green dot much better in any light situation. I paid the same amount for both. They say that the green will eat the battery life faster than the red, but you have to remember that using a green dot does not have to be as bright as a red dot to pick up. Just my opinion. I enjoy using both of them.
"This hasn’t happened to either of my Holosuns so far, but I can certainly see the potential.
Whenever this happens, I just wipe away the dirt and everything is good to go again. It’s a minor inconvenience, but it doesn’t distract or detract from my shooting in any way."
Wait. So has it happened to you or not? This is very confusing because you appear to immediately contradict yourself.
One added point. I served in USASOC in the late 90s. Red Dots were the rage (think old school COMP-Ms - ooh shiny!). Fast forward 20 years and that same red dot is bouncing all over the target. Why? Stigmatisms. 3 in the right, 2 in the left. So here's the choice - pay $750+ per eye to clear up my stigmatisms (and I will still need bifocals in less than 10 years), or get a combo red/green dot for a reflex site for 1/2 price, or get a straight green dot for 1/3 of the price. Choices and decisions.
My gun shop guy suggested the 507C, not the 510C(?). Any problem with the 507C? Thanks, Paul T.
No problems whatsoever. You will not be disappointed. Easy to zero, reticle is clear and highly visible with the 32 MoA ring and dot. Great products.
Even though this is a year old article, I found it very informative. I'm new to everything and have decided on Green because of it. My OLights are Green Lasers so...... I think I might prefer the multiple reticle version as well, since my G17 is mated to a MCK. Now to find the best deal. [crosses fingers]
Thank you!
While the Amazon 'buy it now' links seem useful at first, once you dive deeper into the reviews, you'll find a gazillion complaints that most of these products Amazon pimps are counterfeits. Imagine blowing $400+ on a fake Trijicon MRO! Is that how Bezos funds his space jaunts?!
Can you guys please start posting links to more reliable and carefully vetted resellers?
Has anybody else experienced this problem? I have a Romeo Predator and my red laser will not show through it.
It seems as though there is a coating on the lens that filters out the red laser?
Green dots are just easier on my eyes, been preferring the larger MOA ring with a dot. 65 MOA ring for rifle, and 32 MOA ring for PCC. You left out the Sig Romeo5 with the predator green triangle... fun!
David, Can't seem to find the HE510C-GR anywhere! Any ideas??
Set up in-stock emails and hope :( I had to wait a few weeks when I ordered mine, they come in waves and sell out fairly quickly.
my 3 yr old, cheap sightmark has a choice of red or green, dot or circle, and as I recall, cost around $160. havent killed it yet. it sits a 45 degree angle on my forward grip so i can transition to it off my scope, all this on an a.r. it does munch batteries, however.
Love the OEM three-point green (Tritium) sights on my EDC SIG P365. 'Nuff said.
in my day we used iron sights uphill both ways, through the snow, with no boots on!
You had iron sites?
You’re lucky!
In my day, we......
Yeah, but you guys probably cheated and had rifling, too. Whereas, back in the day....
Writer writes "bad eyes etc."....I have the worst eyes at 57 yrs. I always hated red dots. When I bought my Ruger PC9 and added a Holosun HE510C GR, I was in love. I shot a USPSA PCC match and couldn't miss, especially various steel. Now I'm looking for a Holosun for my M&P 40L to replace the famed Delta Point that came with it.
I love green. Thanks for the article with times.
Tom
would a dab of green paint on my front iron improve my shots? I didn't realize when I bought my AR that the gun was the least expensive part of the equation.
Some finger nail polish on front irons is an old school way of getting some more contrast on ccw guns.
Not sure it would help much on an AR since the front sight is further out.
Can't hurt to try though.
use photoluminescent paint, big improvement for a few bucks.
David is an EXCELLENT writer, in my humble opinion. This is a very well written article that goes a LONG way to explain an interesting and timely subject for shooters.
Thanks, David!
Glad to help!
Yeah! Great article! Thanks, David!
I am an Eotech fan myself, but the others here are great alternatives, especially at those price points.
David,
Can't seem to find the HE510C-GR anywhere! Any ideas??
What holster you use with that Glock 19 with an optic ?
I've been using an OWB Dara Holster. Great retention, smooth draw, I like it. Almost all of their holsters come standard with an optic cut.
Great article, I'm in the market and will consider a green dot now.
I recently put an Eotech XPS3 on a M4. It’s a great optic, the sight picture is phenomenal. I really debated on green or red, If my primary use was in daylight, I really think I would prefer green. However I decided on red for low light conditions.
Super pleased with my Swampfox optics Blade, green reticle. With coupons it was little over $200
okay, first of all, i appreciate all the effort you put into your content. that said, i purchased a holosun and was disappointed... the product arrived with one lens ajar... it appears it was just not seated properly when manufactured... though a possible small chip on one edge could indicate damage in shipping... but, my box was not damaged at all, also it’s made in china... i am putting effort into not purchasing anything made in china... for one, it is a communist nation... i’ll leave the rest for other discussions... please stop using and promoting products produced by communists and start informing us where a product is manufactured if you’re featuring it on your site... 82nd Airborne, gulf war vet
There really aren't many optics, especially red dots, that aren't made in China right now. Leupold has some options but I've heard very disappointing things about them, Aimpoint and EOTech are options but are very steep increases in price.
No excuses please ... stop supporting communist China!

You know it’s supposed to look like that right?
Question- would a green dot be harder to pick up in foliage?
Yes, which is partly why I exchanged a Holosun 515GR for the red version. I also found I had an easier time associating red with "go" on targets, but I'm sure that could be trained away if I wanted.
Because foliage is often green too.
I haven't found that to be the case, but most of my shooting is in the desert. Thinking back to spending the summers in GA, I could see that type of green as possibly being an issue.
I just purchased the HE515CM-GR Elite for use on a CZ Scorpion Evo. It is circle dot and dot only. What are your thoughts on this one?
I bought one for my Scorpion and exchanged it for a red one. The optic is pretty solid, passing some pretty rough tests. The color is up to personal preference.
If you are on the fence I suggest getting a cheap red and green optic with multiple reticles to test color preference. That also helped me learn circle dot reticles look cleaner to my eyes than single dots.
Why so stinkin' expensive?
what about the Vortex Razor?
