What can I say about this product? It works great! I wish I had this earlier. It would have made simple gunsmithing much easier. The fit was perfect. There was no room to twist or bind. It works with flat top and A1 style rifles.

A real waste, what does it fit? ad is very deceptive. Looks good on paper but not so. Went to a friend to borrow his and he has the same problem. So far I have not been lucky at all with Optics Planet.
