·So the other night I put on a front hand guard on my RRA AR. Everything went perfect. gas tube is pinned in the gas block and fits into the bolt key. When shooting today, it will fire a round, not eject, so not cycle. i can manually recock after every shot, but not automatically. Everything is back together fine. The only thing i can think of is somehow there is a hole in the gas tube. Can anyone else think of any other reason this would happen?
