Most Helpful Positive Review Perfect SHTF Optic
Marine approved. Very accurate. ACSS reticule is made for Combat. Built tough and for the budget I couldn’t recommend it enough. I have it on an M&P15 Sport 2 and I couldn’t be happier. Sub MOA at 100 yards with Federal Premium 62gr LAP “green tip” with a 1/9 twist 16” barrel. One thing that makes ...

Very happy

by Capt Jack, from VA, United States Written on February 17, 2026
I'm still a bit of a novice with optics. But I will say that this is a very well made piece of equipment. I have not gotten to the range yet, but look forward to it.

Awesome prism optic!

by Stephen Serpico, Verified Owner from TN, United States Written on February 10, 2026
I wanted an ACOG type prism optic but I wasn’t gonna pay 1K for it. I feel this is on par if not slightly better. Very rugged and durable as well.

This Optic ROCKS

by Shakakan, Verified Owner from ID, United States Written on January 10, 2026
The build quality and features of this optic are great and robust. The etched ACSS reticle is crisp, clear, and sharp when illuminated. The glass on the optic is pretty dang-near crystal clear. The optic doesn't add that much weight to my AK and my rifle feels nice and balanced with it installed. The eye relief adjustments make this incredibly user friendly. I highly recommend this to AK owners wanting a 0-300yrd rifle setup.
Pros:
  • Ease of use
  • Clarity
  • Build quality
  • maintains zero
  • etched reticle
Cons:
  • heavier than a red dot
Best Used for:
  • hunting
  • competition
  • CQB
  • AK47

Clear and reliable

by Tactical cat, Verified Owner from NC, United States Written on June 7, 2025
Planned on using a regular red dot but apparently my astigmatism didn't like them much. Saw the 5X version of this PA prism and it was perfect except I wanted 1 or 3x.This 3x is excellent. Feels sturdy, easy to use, and the glass is clear. I like the sight is easily usable with or without the reticule light being on. When the reticule light is on it can get really bright. Only negative is that is doesn't includes green like the 5x version.
Pros:
  • Sturdy
  • Clear
  • Etcched Reticle
Cons:
  • No green light
Would recommend: Yes

Great Optic

by Andree88, Verified Owner from KY, United States Written on March 11, 2025
Quality optic backed by a lifetime guarantee. Great reticle with very useful ranging, wind and lead estimates. Very crisp and clear. Easy to adjust. Not really anything bad to say.

Fyi the manual only lists the torque specs for the mini 1913 rail on top. I emailed primary arms to get the other... The hex screws on the bottom, to change riser height, are 15-18 in lbs and the torx crossbolts, to mount to the rail of your rifle, are 20-25 in lbs
