I've shot this gun already and it does shoot fine, but I've noticed a problem. The barrel, while it does seat all of the way into the receiver and mates properly, has a gap between the vent rib and the receiver as well as the mag tube and barrel link. I've attached pictures. The barrel, can be moved slightly if you grab a hold of it and twist. Also, w/o a shell in, while the forearm is all of the way forward, you can move it about the same distance the gap is. Is this going to be problematic? I can solve this by throwing the barrel on a lathe and trimming off the excess.
