Hey all, I have a few hundred rounds through my RRA NM4 and was cleaning it today after the weekend match. I found that the cam pin wouldn't insert back into the side hole of the bolt, the lip of which seemed to be bent preventing reinsertion. I ordered a new bolt and cam pin from RRA but wondered if this damage to the bolt might indicate a problem elsewhere in the bolt carrier. Anybody else have this problem? Wanna kill these ads? We can help!
