Ok guys I just got my BCM upper in and the BCM BCG The question is and I know it's stupid but how do I install the BCG into the rifle? I've looked at a youtube video and the guy said make sure the bolt was forward and I've seen a few where it's looks foward but mine sits tight against the carrier. Well mine doesn't move nor does it just drop in. Is there something I need to do to it first? It seems like the cam I think that's what it's called is hitting the side also Not the best cell phone pics Wanna kill these ads? We can help!
