The Primary Arms 1-6x24 second focal plane scope (Gen III) features our exclusive, patented Advanced Combined Sighting System reticle. Bullet drop compensation, wind holds, moving target leads and range estimation are seamlessly integrated into an easy to use, instinctive sighting system that is very fast from 0-300 yards and very accurate from 300-800 yards. The second focal plane design keeps the reticle the same size at all magnifications for quick acquisition at low power and advanced reticle functionality at 6x maximum power.
We knew our flagship Gen II 1-6x24 would be a tough act to follow, so we worked hard to make incremental but real improvements. The Gen III is 18mm shorter (10.04in long), weighs 1.88 ounces less (16.9 oz. total), and has an additional 10 MOA of internal adjustment compared to the older model. The ACSS® reticle has also been improved, now featuring a chevron center aiming point rather than a dot.
Partial red reticle illumination is provided by a single (included) CR2032 battery, and a spare battery is included inside the windage turret cap. A total of 11 settings take the reticle all the way up to daylight bright. All lenses are fully multicoated for maximum light transmission and the 6063 aluminum body is Type II hard anodized in matte black. Flip-up lens covers are included, and a "cat tail" scope lever is available from 3 Gun Stuff (product code GS-460).
Flip-cap scope covers are included, but for customers who wish to upgrade the Butler Creek flip-cap sizes are:

Ratings & Reviews
Best scope for the $$$
Bought this scope for latest AR build. Did a ton of research online, watched many reviews and this optic kept coming out on top. Here are five reasons to buy. 1. price 2. ACSS reticle 3. Chevron. 4 super clear glass 5. lifetime warranty
I decided to go with this scope after countless hours of research, and having great past experiences with Primary Arms. Their customer service and fast shipping has earned my business. The scope is of very high quality and the reticle is absolutely amazing. I mounted it on an American Defense Scout and couldn't be happier with this product. It was between this and the Vortex Strike Eagle. The ACSS reticle was far more appealing to me, and having the confidence of Primary Arms lifetime warranty helped make my decision very easy. My friends have decided to purchase this scope as well after seeing it in person. You will not regret buying this product. Thank you Primary Arms!
Best AR-15 optic in its price range
by Raymond -
Got to try this scope out at the range on a brand new build yesterday. I zeroed the rifle in at 100 yards. (16" barrel, with 1:7 twist, using 62gr ammo) I am very impressed, especially considering the price . I truly believe this is one of the best values out there for AR-15 optics. I know there are better, more expensive options, but for the money, this scope beats all the other optics I have tried at the same price range. I highly recommend this scope and will definitely be buying more very soon! I'm also very happy with Primary Arms. I also purchased a completed upper from them on an earlier order. This scope and the upper were both shipped quickly and extremely well packed. They also responded to an email of mine in a very timely manner. They have definitely earned my business and trust.
Pretty awesome for the $$$
Been running this scope for a while now and there’s no doubt it’s pretty awesome for the $$$. I figured out, for me, that the eye relief you set it up with is huge, as it’s more generous IMO than advertised... meaning it’s far more forgiving if you’re further off/back of it than too close. I’ve found you get much more of a true 1x at 1x if you find the sweet spot (and where 6x still isn’t too finicky), which was a couple piccatiny notches forward of where I initially mounted it.
<br>Really my only complaint is that I wish only the chevron, or horseshoe and chevron, were illuminated... because the whole “christmas tree” being lit IMO can be a distraction...
Since this is a second focal plane scope, at what magnification is the reticle the most precise? At full magnification?
by Cory -
First scope received was defective out of the box, may have been bad handling by shipping company, ACSS reticle was low and to the left and would not adjust enough. Called tech support and discussed the issue with Keith, after talking and determining that something was off in the scope, was issued an RMA and returned scope and received replacement in less then a week. Installed replacement scope and did a basic boresight by looking thru barrel and scope. Took to the range and within 6 shots had it sighted in and shooting inch groups at 100 yds. So far an excellent product for the money and as usual outstanding customer support from PA.
As good as if not better than scopes twice its price
by Robert -
Great scope , very clr glass and reticle , i was really suprised with the amount of eye relief the scope allows. Ive only used around 500 rounds with it so far it seems very well built and the acss reticle works great. The american def mount is very nice , well built and very easy to install.
Can't beat a ACSS Reticle Scope
by John -
I ordered this scope after watching a number of videos and reading good reviews for this scope.When I got it and opened the packaged and looked though the scope I had my doubts,I said to myself how in the heck am going see that little bitty reticle did I just make a mistake buying this.I wear glasses and getting long in the tooth,getting a little harder for me to see.But after reading how to set it up Wham it was pretty dang clear,I could see just fine,I took it to the range and had my MOA groupings close by 1/2 to 3/4 inches from 2 inches out to 100 yards using Federal XM193 5.56 55 Gr. ammo out of my Colt LE6920 1-7 twist. This scope to me is a blessing,especially where I hunt here in SE Texas Brush Thickets.I'm really glad I got me one.
Buy this scope

Fantastic scope. Have only put 300 rounds through my AR with it mounted but so far it's perfect. Farthest distance I had a chance to shoot was 300 yards give or take a few. The auto ranging was easy to use and had no problem hitting 12" steel. 1x magnification is not quite 1x, just a little more but still had no problem shooting fast at close range. It is maybe a little more than 90% as fast within 20 yards as my Primary arms micro dot and about equal out to 50 yards, but beyond that having the ability to turn the magnification up makes is significantly faster to acquire targets at range. Only change i made was adding a breakaway nylon coaster (throw lever) which makes changing magnification much faster. Absolutely no regrets, buy this scope.
Great Price, Decent Quality
by Walter -
I am giving this scope a 5 star rating simply because of its value. I personally recommend this scope and would buy one again if I ever part from it in the future. Its not as high quality as a Viper Vortex PST, but its close. Pictures in the link...
Anticipating first trip to the range.
by Craig -
I have been researching the PA 1x6 gen 3 for many days now. After viewing YouTube reviews and engaging in other research with little to no negative results I decided to order the scope. I am eagerly awaiting its arrival and getting it to the range for zeroing and testing. I use Hornady 75 gr and Corbon 69 gr OTM for my defense loads from a Sig Sauer 516 patrol rifle gen 2 upper 1/7 twist 16" barrel with a Surefire Warcomp flash hider. The lower has a Giesele SSA trigger. I can't wait to get to the range lol. Range report forth coming.

Great scope, well made and works perfect with my AR 15 & 308. Fast delivery by Primary Arms.
Best Value in Rifle Glass, Bar None
by Andy -
Took this to CMP Talledega a few days ago and I'm pretty impressed. For under $300 I don't think anything else can compete with this scope. Sure it isn't perfectly 1x, there is a little distortion around the edge and it isn't the lightest but you'd be hard pressed to find anything under $500 that aces any of that. Shooting at 100yds got boring very quickly it was so easy. The reticle was dead on at 200 and 300 yards. Pushing out to 600 with 55gr I noticed the reticle was a little off but the fact that I was hitting in 18" by my third shot says something about how easy this reticle is to use. For me this scope beats the Strike Eagles in clarity alone. I'm going to be considering PA Optics a lot more now.
Ok for the price.
by Cade57 -
The reticle is way better than I thought it would be. The new chevron allows for precise shooting. The scope is very clear but on 1x there is some washing around the outside of the glass. The illumination is useless on less than 4 even at night and there is no off between brightness settings. It is also very heavy. I would have gave 3 stars for the weight, but I knew before ordering it, and it's on par with other scopes in its class. I'm kind of disappointed due to the build I put it on because I spent a good bit extra $ on keeping it light weight.
Great initial impressions, can't wait to shoot with it.
by Michael P. -
So far, so good with this scope. Glass seems to be clear enough presenting the rifle out in the back yard. It doesn't have a completely true 1x (some SLIGHT magnification at 1 power) but is totally doable with both eyes open so long as you're looking more than about 5 yards ahead. Illumination is super bright even in the daylight; I wish there was an off button between each setting. Turret clicks feel solid and move with a positive, tactile click. Magnification ring moves smoothly with just the right amount of resistance. There's really no frills with this scope, it's all business with that ACSS reticle inside. Only time will tell with build quality, but with PA's warranty and this scope's rock solid reputation you can't beat it for the price. I cannot wait to take it to the range and try out the BDC.
Buy this scope
by John from AZ
Seems like a lot of reviews don't really review the item.
<br>Here is my feeble attempt.
<br>First off, the glass is clear. Vortex diamondback clear. Not us optics clear.
<br>Eye relief is moderate and suits a fast firing use
<br>The weight of the scope is not a huge issue as there are some weight savings in a quality mount.
<br>Windage and elevation work correctly.
<br>The acss reticle is awesome for fast fire.
<br>The ranging and target lead are spot on. If you anticipate shooting something running then these will work for you. I bought the gen 3 scope just after it came out and the ar15 that it sits on has helped me take a bunch of coyotes
<br>Running standing sitting. This scope will take the guesswork out of your ranging and help you put rounds on your target.
<br>I would strongly recommend this scope
Very impessed! Seems to be high quality
I got to use this optic on a BCM AR15 in a charity match and was very impressed with it. We were engaging 6" or 8" plates from 250yds out to 326yds. The reticle was very easy to use and very accurate with the subtensions. The illumination was very crisp and clear as well. I am strongly considering this optic for my personal AR. The only reason I'm not giving 5 stars is because I don't have much time behind the optic. However, Primary Arms always has great customer service and super fast shipping
Buy it, you cant go wrong.
by Ct Smith
Bought this a few weeks back, tried it out today, fantastic results. This is a do it all optic. Up close it works like a red dot.. 100 yards or more it works like a scope. I will be buying more of these for the rest of the Ar's in my house. Dont hesitate buy it before i do.
First time reviewer/First time AR user (Ruger AR-556) GREAT SCOPE !!
by Fred -
After seeing a review about this scope on You Tube by 'sootch00', man it seemed a natural choice for my newly purchase Ruger AR-556.<br>Am new shooter, sport and target only as I do not hunt since Viet Nam but I can't wait to get it on the rifle and use it. <br>I researched several reviewers on You Tube and every one seemed to have the exact same thing to say - Great scope/excellent quality !!!<br>That made the deal for me<br>I would give it a very high recommendation but, I have not yet got to use it. <br>Especially for someone my age of 70 with less than perfect vision<br>God Bless
Great Variable AR Scope with Superb Reticle
by John from SLC
This is my first variable-power scope. My go-to optic has been a Vortex Spitfire 3x up to this point. After reading and viewing reviews I chose this over the Strike Eagle, and over other scopes costing exponentially more. I mounted it on a POF Renegade+ with an AmDef Recon mount. Took it to a 4-night rifle class. Amazing results! Hitting steel at 400 yards, head shots at 50. Good eye relief for fast target acquisition. I'm near-sighted and keep the power at 3x most of the time. Scope is awesome.
A good choice
I put one of these on my DPMS 308 and I'm very happy to say it's a good choice. The 1x is very clear with a huge field of view 6x is crisp with good eye relief. I researched many brands and I'm glad I went with Primary Arms.
Pleasantly Surprised and Quite Impressed!
First, I’m a bit of a scope snob. Not because I’m independently wealthy, but because I’ve always lived by the "buy once, cry once" philosophy. If the scope didn't start in the $800 range, I didn't give it a second look. I didn't want to replace it in a year or end up wishing I’d paid a little more for better glass. What good is an accurate rifle if you can't see through the optic? I also discounted Chinese-made scopes contracted out by companies that were not in the scope-making business (think Vortex, Leupold, Burris). I now own a PA 1-6x Gen 3, PA 1-8x, and PA 4-14x. Primary Arms has put all these reservations to rest! Is the glass or eyebox as nice as my $1000 1-6x FFP scope? No, but it gives it a run for the money, and is $700 cheaper! I am very happy with this scope. So, if you were like me agonizing about whether or not this scope was really worth spending your hard-earned money on, DOUBT NO LONGER!
Overall Happy, But...
by Jared -
Overall Happy. Glass is clear. However:
<br>Top portion of eye box is blurry, so full eyebox is pretty well unusable to me.
<br>Mine weighed 17-18 oz, far from the 15.52 oz advertised weight. I know 15.52 oz is without battery/caps/flip ups, but nobody runs them like that to claim they are 1.88 oz lighter than the Gen II (17.4 oz).
<br>Lastly, I preferred the center dot over the chevron. I know the chevron is for a more precise zero, but a BDC reticle isn't a precision reticle, which is why i like the dot. It covered a 1/2" paster at 100 yds almost perfectly.
Awesome glass, clarity, reticle, etc. Value is off the charts with this scope. If you do not like the reticle on the Vortex Strike Eagle, definitely pick this up.
by James -
I purchased this for 3-gun. It is an amazing scope. Clear and bright with bright illumination. I looked at a lot of other scopes but the reticles didn't wow me. The lifetime warranty and chevron of the Gen III made me "take a risk" on this one (that and the good things I have heard about it) and it has really won me over.
