Another range report. A lot to say so I'm going to summarize.
Range Report:
Fired 120 rds of the PMC Bronze (First 50rds+ were fired without issue), 60 rounds of the Monarch.
4 total FTFs with the PMC Bronze, several failures to lock back.
No failures with the Monarch (FTFs or failure to lock backs).
This hints at an ammo issue as I used the same mag for all 180rd.
BUT My ejection pattern DEFINITELY hints at a short-cycling issue as the brass was behind the bay of the other guys to my right.
AND
Did another gas ring check, and now it
does "collapse" under the weight of the bolt carrier. It did not before, but now it does.
I put the bolt in another Bolt carrier and it DOES NOT collapse under the weight of that one. This bolt carrier is a little lighter than the stock one.
Again, I'm fairly new so I have no idea whats going on here anymore. I'm confused
Could I just swap the whole BCG?
Thanks to anyone still hanging around and has the patience to deal with me
