Optic good; base, not so much.


I've had one of these for over a year now. Overall quality seems to be quite good (still works like it should, very little tint to the glass). I haven't particularly abused it, though, just casual range usage (mostly with a 5.56 AR-15). The weak part so far was the base's clamping screw. Using the low base, I attached the sight to my (9mm) Ruger PC Carbine. About five shots later, the sight flopped to the floor. The crossbolt screw had snapped at the clamping piece. Do yourself a favor and just get an aftermarket Aimpoint Micro-compatible base.
