Most Helpful Positive Review Small & lite
Personally I think it's overpriced. Other than the price it's awesome. Very small & lite for use on AR style "pistols". Good field of view. Black etched reticle with good pattern but only in red when illuminated. Once you get over the price, you'll really like it! Ct.
Most Helpful Negative Review Poor eye relief
If your looking at this sight it’s probably because your looking for a 3x prism sight the size and weight of a red dot. Well, here it is. This optic is super clear crisp and I do like the size of the reticle. Pretty much everything about it was you would want except the eye relief. You need to have ...

If I could afford it is buy three more

by Dogtired, Verified Owner from VA, United States Written on August 13, 2026
Put one on my ultralight build, and now wish I had the funds to put them on my 11.5" 556, 10.5" Blackout, and 10mm AR. Great weight, and about perfect for a 50-100 yard tree stand gun. Great etched reticle that's visible when no illumination is present. Built in mount makes it easy to set up. Clear glass with a decent field of view and plenty of eye relief. Comes with a lifetime warranty. What else do you want? Might just sell off a rifle to buy more of these!

Zero Eye Relief

by Sleaze, Verified Owner from TX, United States Written on August 6, 2026
I bought two, thought it was a stronger optic but it isn’t.

Eye relief and parallax on this is really rough.

Could work on smaller calibers, but need to be recoil conscious.

Decent optic for a pretty good price.

by Dead Bear, Verified Owner from CA, United States Written on July 1, 2026
It seems solid, and nicely built. Glass clarity is good, and it doesn’t weigh very much. Eye relief is very tight though, and the reticle is even smaller than I expected. Tried it out on an AR, and it’s just not comfortable, or easy to use due to the short eye relief, and the vignetting. I’m gonna put it on a .22 that I have instead, it should be just fine for that.
Pros:
  • Price
  • Weight
  • Ease of install
Cons:
  • Short eye relief
  • Small reticle
Best Used for:
  • plinking
Would recommend: Yes

Eye relief is bad

by Green Dog, Verified Owner from AZ, United States Written on June 22, 2026
I mean you pay for what you get (172)
It is decent overall, not the best for sure, but it is good for the price if it stays cheap.
I would recommend not using this optic on an AR-15 platform. Best for DMR or AR10, just for fun, I would not recommend this for serious use
i would give this a 7/10
Pros:
  • Redical and price
Cons:
  • tight - very sensitive eyebox
  • Not for an AR 15
  • Eye relief a little close, tight eye box
Best Used for:
  • For Fun For Target Practice
  • AR 10 DPMS PLATFORMS
  • DMR Type Set Up, Hunting Rifle
Would recommend: Yes

Yes but understand what you are getting

by TBowman, Verified Owner from VA, United States Written on June 5, 2026
Overall for the deep discount it performs well on a PSA 9mm. The lines are there but to small for any real distance shooting in my opinion. It is a nice optic!!
Pros:
  • small and compact
Cons:
  • You are going to pretty much use it as a red dot
Best Used for:
  • Anything out to about 100 yards
Would recommend: Yes

perfect for what we needed

by Medic 37, Verified Owner from MT, United States Written on June 2, 2026
this thing was perfect for our needs. got it as a present for my dad for Father's Day. integrated mount, so his install process was easy. it has the etched reticle which can be seen with or without the illumination. he also has astigmatism, so again, the etched reticle is key. its plenty light-weight, and easily zeroed- more importantly, it holds that. zero. another key, he can use it for cab/home defense. as much as we loved the idea of an LPVO for this purpose, it just can't compare. the idea of mounting a red dot on an LPVO is just ridiculous, especially when you have the option of a prism available, and for a reasonable price. if you want an optic that does its job, and does it reliably, consider this guy. lifetime warranty? yeah, that's a plus, I guess. I've compared this to my PA SL3x MicroPrism and while there's quite a few differences, it's perfect for his needs and for the price. very happy with the purchase.
Pros:
  • Lightweight
  • reputable brand
  • integrated mount
  • Price and warranty
  • easy to use
  • etched and illuminated reticle
Cons:
  • glare at high brightness levels
Best Used for:
  • CQB
  • Short & medium distance shooting
Would recommend: Yes

good clear glass but eye releif is a little short

by B-rad, Verified Owner from CA, United States Written on May 28, 2026
Just put this on a .22lr and it is Nice clear glass and works excellent as set up but the eye relief might be a problem with a higher caliber rifle like .308 etc. The Illumination is good and its not too heavy so overall 4 out of 5 stars.
Pros:
  • Lightweight
Cons:
  • Short eye relief
Best Used for:
  • Plinking & target practice
Would recommend: Yes

Tight Eye Box

by S. Templar, D.D., Verified Owner from WV, United States Written on May 27, 2026
It's crystal clear and extremely well made. The usable eyebox is tight, but no worse that a traditional tube scope.

I really like it. The view is super clear. Definitely recommended, but don't expect a red dot eye relief.

GREAT OPTICS

by EMMETT, from NE, United States Written on May 20, 2026

Pros:
  • etched reteicle
Cons:
  • None
Best Used for:
  • up to 100 yard hunting
Would recommend: Yes
