I picked up a new side charger upper for my M11/9. For some reason it will not run with the CF-W bolt. The bolt will push a round in the chamber but not fire it. When I have got the rounds to fire, I get two or three rounds then it locks open like it's on semi. I ran it with the factory bolt and it emptied the mag in seconds.
A second issue, it seems that the top rail is smaller than it should be. I tried to put a new Holosun scope on it. It can't clamp down enough to lock tight. The scope does fit several other uppers with no issues. I tried to put my old OKO sight on it, same thing. It can't clamp down enough. I actually broke s screw off the OKO trying to tighten it. (I have no idea how to find a screw for an OKO sight). Have others had these issues? I may have to ask for my money back.
