Most Helpful Positive Review great optic
This may be the best optic i own. sturdy and very well built have heard a lot about them and when i saw it on sale i grabbed it. no regrets. easy to use the magnifier swings out of the way when not needed.
Most Helpful Negative Review Very dim, not stable (design feature duh, both the turret of the reddot, and the magnifier)
For the price, I should have gone with EOTech holographic. As some youtube reviewers said, and I regret not knowing, that the projector and the screen are not sealed, so if you get dirt on both the inside of the screen, or the projector, it will block the dot from appearing.

The magnifier on par with the Eotech

by Michigan Backcountry Redneck, Verified Owner from MI, United States Written on December 16, 2023
I got this combo for a smokin hot deal. Something ridiculously low like around $600. Just can’t beat it for a military grade weapon’s sight. The glass is clear reticle crisp. The magnifier was the most impressive part of the bundle. It had generous eye relief like the eotech. Only difference is it uses a button to open and close. I own several m21’s if you do purchase one, fyi they need the polarizer kit. Even with the polarizer they are still cheaper than eotech and trijicon which I also own and would say they are on par with.
Pros:
  • cost
  • no batteries
  • High quaility
Cons:
  • Polarizer must be used w/weaponlight
  • polarizer is not included
Best Used for:
  • DAY OR NIGHT
  • Hunting, self defense
Would recommend: Yes
