Last evening I had the opportunity to shoot my XCR-L 5.56 pistol with a friend. It shot great overall, but partway through my friend’s shooting, there were two failures to eject. Before this session, the gun had fired 150 rounds, with and without suppressor, without any failures.
We discovered that the barrel was loose and could move forward about 1/2”. Before shooting this gun when it was new, I tightened the barrel retention bolt to spec but did not remove and reseat the barrel. So after the session yesterday I loosened the retention bolt, removed and inspected the barrel, then returned it to position. I think that I now have it seated all the way down, and I tightened the retention bolt back to spec, 200 inch pounds.
Has anyone had this happen? My preliminary conclusion is that the barrel was not originally completely seated, so the barrel retention bolt was pushing against the extension but not in its dimple. I’m nervous about possible damage from what happened yesterday, but I can’t see any problems. It’s hard to know when the weapon is all new to me so I don’t know what’s normal. It all looks good.
any ideas? Advice?
