Most Helpful Positive Review Solid optic
Well built, clear glass, great price on here. Can’t go wrong with this one at this price.
Most Helpful Negative Review Good glass, bad mount. Overpriced.
The claim that it will co-witness with 1.4" height iron sights is false! The lowest the mount will go is 1/3 lower co-witness. The glass quality & clarity is good, though. It's too bad the mount was not well designed. Overall, this is way overpriced compared to other options.

Reccommend but caution

by Dave, Verified Owner from AZ, United States Written on October 24, 2025
I gotta say, size and weight on par with all micro magnifiers, 4x is perfect. The box/ packaging is nice, has a black rubber cover and a tan rubber cover all the tools needed to adjust, extra plate to adjust height and longer screws. Diopter rear adjust nice and the glass is clear. Mount is flip to the side and has a solid feel with tension. Long term not sure but feels goood new. Only issue I have and was never a thought. If you look at the body of the magnifier the mount bolts directly into the center of the magnifier, which if running back up irons (Magpul pro) and Eotech exps series and don’t want your optic mounted onto part of the rail you don’t have enough space. When you try to flip into place it hits the body of the Eotech. I had to compromise against my better belief and move my optic 1 slot onto the rail, with 300 blk out I assume won’t have an accuracy issue based on range I plan on shooting. Always been taught a no no to mount that far forward and to keep optic on upper receiver. But for the price and the quality the magnifier is prettty sweet. Btw I couldn’t find adaptor plates or different mount to fix my issue. Maybe down the road and cantilever style mount will come out.
Pros:
  • Quality , price and all the little accessories
Cons:
  • Hits Eotech exps if running backup sites and want to keep your optic on the upper receiver
Best Used for:
  • Help zero, fun plinking and all your tactical needs to be a ninja
Would recommend: Yes

Excellent optic.

I've tried every magnifier, this is the best

by GrayFox, from TX, United States Written on August 11, 2025
After trying every magnifier on the market, these are the best. The glass is crystal, and the magnifier feels durable with a nice removable sleeve.

The mount is fine and works just fine for what it is, it's a simple flip mount but sturdy.
Pros:
  • Price
  • Durability
  • glass
Cons:
  • None
Would recommend: Yes

Tough Eye Relief

by PShep, Verified Owner from NJ, United States Written on June 29, 2025
Optics are clear and clean, magnification level of 4x is great and focus ring is perfect. My only draw back to this item is the difficulty with eye relief. Hoping it gets easier as I get used to it, but the first two uses have been a challenge
