Despite its cool factor, it does not hold zero. not recommended until issue is addressed. - Meprolight M22 Rifle 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
