So after installing my Or3gun MST, CSP, and CFR I took my 930 out to bust some clays yesterday with some friends. Ran a few rounds through the 18.5" setup first to try my new NC mag extension, found out I needed the longer NC spring for it to chamber the last round, no big deal though. I put a spacer behind the spring until I can get home and tinker with it, and verify it runs fine with the 18.5 barrel, flawlessly in fact, but it did that in stock trim too.
Switched out barrels for the 28" vent rib barrel, and the gun will not cycle, period. It will fire the first shell, but not eject it, every single time. Gun was clean as a pin when we started, as I clean my guns every time we got out, including the piston, rings, etc. I tore it down to check for anything obvious, and re-assembled only to get the same results. Ammo was Federal bulk box 7.5 shot 1200fps loads that it's ran fantastic up to this point. One thing I do notice is that with the CFR, I have to sort of push my foregrip up towards the barrel to get it to seat completely, and the pusher assembly has some noticeable wear marks where it's been rubbing something. Inside of the forearm maybe? But, it's the same way with either barrel, and didn't prevent the 18.5 from cycling flawlessly.
Any ideas at all? Maybe the comp MST is too light for the 28" barrel possibly? Hell, I'm stumped.
