I built this one out last year, I think?
CMMG Colt-mag lower. PSA build kit. PSA 4” upper. Form 1 silencer. I think the buffer is 7oz...definitely a heavier/longer PCC style.
I’ve had it out a handful of times, and once every mag or two (or three) I have the same issue, or at least a very similar issue. I’ve just never taken the time to try and figure it out. Well today, it happened again while I was shooting it and while @Zbizzle911 was shooting it.
Basic description is I usually end up with an empty case sticking out the ejection port, with a new round being chambered by the bolt. Looks like this:
In this case, it was the last two rounds in the mag. But I’ve had it happen with the 2nd and 3rd rounds, two rounds out of the middle, and anywhere else. It’s happened with 20rd mags and 32rd mags...so I don’t think it’s mag related, especially since it’s stripping off the next round each time.
While it normally has a stove piped piece of brass, every once in awhile it’s this instead:
...where the empty didn’t make it completely out but the fresh round was headed to the chamber.
It’s almost like the empty isn’t being tossed out like it should.
Any ideas on things to check? Things to test? I can’t intentionally make it happen. It’s never more often than once every 15-25 rounds...and sometimes it’ll go an entire mag or two trouble-free.
My 9mm SBR has never had this issue, so I’m not even sure where to start.
