The heart of our tough Gen III 3X Prism Scope is the improved ACSS-CQB 300BLK/7.62x39 reticle that combines ranging, wind leads, moving target leads, and ballistic drop compensation out to 600 yards. The outer horseshoe of the glass etched reticle is used for close quarters engagement, simply place the generous semi-circle on the target and run with it! Each side of the horseshoe also has our integrated ranging system. Place the bottom of the target on the bottom rung and range up. If you know your targets are roughly 18 inches wide, they can be ranged on the side Auto Range system, or directly on the BDC hold overs! Two dots on either side of the precision chevron offer a moving target lead moving with an average speed of 6.1 MPH. Each step of the BDC system includes a 5 MPH wind hold, drastically improving first hit probability at any range. As an added bonus, the glass etched reticle does not require batteries or illumination, but 11 brightness settings (including daylight bright) allow for fast acquisition in close quarters, or enhanced visibility in fading light, powered by a common CR2032 battery!

The SLx 3X Gen III has even greater strength and flexibility than ever before with our next generation ruggedized mounting system. We’ve upgraded everything about the mount from materials and finish to the design to create a mount that will not just clamp securely to your rail, but stand up the rigors of real-world use. Integrated recoil lugs help lock your mount in place against the heaviest recoil while large diameter crossbolts give you significantly improved clamping power and will hold up to significant torque. The included riser is the perfect height for AR-15s and AR-10s, but can be easily removed for carry handle or AK use as well.

Fantastic optic!

by -

If you suffer from astigmatism, then this optic is your best bet in place of a red dot. Very clear glass and extremely well built. ACSS Reticle is one of the best out there. I used the American Defense ACOG mount AD-B3. If you want to use the riser that comes with the optic, go to your local hardware store and get 2 10-32x 3/4'' button head screws (per ADM's recommendation) vibratite them and you are good to go

Great optic


Just mounted this on my Sam7sf and love the reticle. Can't wait to bring it to the range.

Good Value and Works as Expected

Etched glass, effective BDC reticle, just the right amount of magnification, and won’t break the bank.

It’s just awesome


I love how bright the light can get. Love that it’s still completely useable without any batteries. Built like a tank. Glass is crystal clear. My ONLY gripe is that it’s made in China. But I also understand that is why it’s priced as affordable as it is.

My New Favorite Optic


I installed this optic on my Palmetto State KS-47 (7.62x39) and I believe it was the best decision I could have made for that platform. I primarily use it for plinking and predator/hog control and it has quickly become my favorite optic, so much so that I just bought PA's new GLX 2x prism with ACSS Gemini reticle for my 9mm carbine. The ACSS reticle has to be tried to be truly appreciated. A wide field of view means target acquisition is extremely fast and the reticle allows for so much flexibility and quickness in ranging targets on the fly. This optic has turned me into an absolute hog hammer, allowing me to stay on target and easily hit pigs on the run. The wide field of view and reference marks for aiming at moving targets is perfect for that application. I love the fact that the reticle is etched on the glass and will always be visible, even when your battery fails. If you are the fence, don't hesitate and try this out. You will not be disappointed.

Perfect for 7.62x39 platform


Love this scope. Kinda impulse bought it when it was in stock briefly. Couldn’t be happier. Pinging 12” steel plates at 200 yards every shot is beyond satisfying.

Worth the money and is spot on.


When I first saw this optic offering. I was a bit doubtful at first. I even saw the videos from a few famous YouTubers about its performance. So I took a risk and put my money where my mouth is the hype is real and it really did show out. It really adds a level of confidence in amazement that I can make a 7.62 x39 round go out to distance and repeat the shot over and over. Even me those nearby surprised at the fact that in a km can go out to 300 yards and have consistent and repeatable impact groups. If you have a chance get one and you will be amazed as I have.

3x32MM Gen 2


This optic takes the 7.62x39 caliber to the next level. I was able to site in rifle at 100 yards then 200,300 & 600 yards. This is a lot of optic for the money. Peace out & God bless America

Awesome scope!

This scope is great! The glass is crystal clear and the reticle is excellent, with or without illumination. I'm not sure if these come zeroed from the factory, but if so, I would guess they were zeroed for 8,000 yards with 95 MPH crosswinds. Took quite a bit of adjustment to get on target with my PSA GF3, but once I got there, was good to go. Love this prism scope and would recommend it to anyone looking for something magnified for their 300 AAC or 7.62x39.

Most versatile optic I own!

by -

This thing has the right level of magnification, super clear glass, nice flip-up lens covers, and the BDC is perfect. On an AR in 7.62x39, I hit consistently in a 5" area at 300 yds. Considering the caliber and platform, that's not bad.
<br>I like it so much that I own 2, and have recommended to friends who have bought it too.
<br>Also, the cost is very accessible, especially as it doesn't require the addition of rings, nor does it require setting up a plumb to get the reticle perfectly square with the rifle.
<br>I note that it comes with a small riser, and suggest buyers to remove it for good co-witness with back-up sights.
