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.

Great optic for astigmatism!
I bought the optic in 2018 during black friday. I picked up the grey wolf color on sale. Fast forward to 10/19/19 I finally went shooting to sight her in. This optic is a godsend for my eyes! The glass is crystal clear and the magnification is great. I was able to put 15 rounds through a quarter size hole while zeroing my rifle. I can no longer use red dots anymore, the dot looks like an exploding star when looking through the optic. Im definitely going to pick up a few more of these scopes.
Love the ACSS. This scope is perfect for what I wanted. Clear glass
WOW shipping was from a fictional movie 2 days I live in florida. WELL DONE STAFF THANK YOU.
Perfect AR Scope
by Matt -
This scope sets the Standard for a 1-6x scope. The glass is clear and crisp from 1x to 6x. The reticle is easy to see and use. The price point makes this a no brainer decision. Shipping was quick, packaging was great. I’ll definitely be a repeat customer with Primary arms.
This scope competes and excels above many $1000 scopes.

The ACSS reticle takes the best of BDC and range estimation and combines then into a single lens, then combines a precision mark with a quick acquisition semi-circle for close quarters. I tested this scope at the same time I tested a binary trigger. The scope made it easy to recover and stay on target for rapid two shot strings. At close range, just put the semi-circle on center mass and pull the trigger. The chevron also made precision shots easy. I found the glass to be clear and the lower settings on the illuminated reticle to work well in low light situations. I personally think the higher settings on the illumination start to distort and blur the reticle, but that could just be my eyesight since I have astigmatism. The instructions are little confusing but there are a few videos that explain the reticle very well. Overall, I think our troops could benefit from this scope and it would be interesting if it were actually tested it in real combat.
1x6 Stike Eagle for sale
If your trying to decide between Primary and Vortex let me save you some time! Hands down this is a better optic. I own both and while you are still trying to find your alignment n get a sight picture on the Vortex Ive already aquired and engaged the target. The eye relief on the PA is far better so much so Ive purchased another PA to replace the Strike Eagle. Im also replaceing the V brand that cost over a grand thats on my Aero P m5 for the PA scope that is same magnification n selling the Vortex. These may be far less expensive but not a cheap knockoff.
Perfect for all skill levels!
Whether you are a master shooter or a beginner with their first carbine, this is the optic for you! I have owned this optic for over a year. I have ran on various rifles and setups, it just flat works. Zero at 100 yards and true it up at 400 and you are set! 55gr to 77gr Mk262. It works! 10/10
Best optic for the money
I just went out and sighted in my new AR today with this scope. I really like it, easy to adjust. I had it zeroed in in 3 shots. It's very clear and I love the reticule. I don't think you can find a better optic for the money. I'm planning on buying another one.
SLX6 1-6X24MM SFP RIFLE SCOPE GEN III - ILLUMINATED ACSS-5.56
by Jason -
Great scope for the AR platform. Took all of 8 shots to zero at 100 yards. Afterwards it was a joy to use. It's super clear, the eyebox is well sized and the ranging makes first shot hits almost too easy to achieve. Was not able to test past 200 yards, but very much looking forward to it. Primary Arms is an amazing company to do business with.
EXTREMELY IMPRESSED!!! I was hitting 10 inch plates and body silhouettes from 300 all the way to 600 yards ! Out of a Smith and Wesson M and P 15 sport 2 16inch barrel 1:9 twist using 55g american eagle XM193 basic ammo. Hold overs are very reliant and accurate. Super happy with my purchase.

EXTREMELY IMPRESSED!!! I was hitting 10inch plates at 300 all the way to 600 yards from a 16inch 1/9 twist smith and wesson using 55g american eagle XM193 basic ammo !!! The hold overs are really on point ! When I got to 600 yards I just had to hold over about 3inched above target using the 600 yard hold over to hit center . Very happy with my purchase!
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
by lucas -
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.
