Bought this sight and mounted it on my Wilson AR15 at 45 degree offset as back up to my 2 - 10 scope.
Was extremely disappointed as the switch broke off before I even got it zeroed.
My impression is that it is a low quality piece of junk, designed more as a gimmick than a piece of shooting equipment.
Also tiny adjustment screws have no click stops. Makes zeroing extremely difficult.
Save money and frustration. Spend more and buy a better quality sight.
This sight is a toy. Not made for shooting.
Pros: Lightweight, low profile
Cons: Low quality, not durable
