Despite its cool factor, it does not hold zero. not recommended until issue is addressed. - Meprolight M22 1x30mm Bullseye Reflex Red Dot Sight

Even tightened down, if you press the optic leftward, it will pivot on the integrated mount. It doesn't require much pressure at all. I have this on both of mine and a friend's. So its not just a one-off thing. I discovered this too late to return them, so I will try to save others from making a $450 + tax and shipping mistake

Otherwise, the optic is quite cool and looks great on AKs especially. Its great in concept bit until they fix this, i dont think its worth the 450 plus tax and shipping. It can be a neat range toy but not serious, yet. I am going to contact optics planet and meprolight and see what they will say, and update this review. If I can, accordingly
