The ruger SFAR is running fine now that the brass debri is out from the firing pin. The Stag arms 5.56 is the one not feeding the pmag gen3. Same mags work in the Christensen arms 5five6 wylde. All three are new less than 100 rds. Each.
The stag arms BCG was lubed with Lucas gun lube and tiny bit of gun grease on bottom of BC. Mag pul says hand cycle full mag. If it works it’s not the mag. That’s easy to try. Relubing the BCG will happen after that and if it didn’t hand cycle the first time I’ll try it again. I get it more lube...
Here is another question while I have your attention. New stag arms 15. Fires with several different plastic mags including pmag gen2. But pmag gen3 doesn’t feed bolt pushes round up to feed ramp then rides over. Usually on 3rd round.
Tried several gen 3 including the pinned 30 rd that hold 10...

Thanks I have not pulled bolt out but plan to do that soon and look at gas rings but it didn’t look like pictures I see of gas rings. It was lubed and once debris was removed it functions fine. Still I’ll look
Could it be something from the gas regulator? I’ll open and inspect it also. I did not know the gas goes into the firing pin chamber. I did say new to ar or did I lol… and it is firing normal now
And there is a fair amount of clearance around front of pin chamber. Also I did not say it was a primer I said part of a primer like part of the ring. It didn’t look like gas rings from pictures I see of those but I’m going to open it and look.
Good info it looked like part of the primer, wind got it before I saved it but I’m going to open it and inspect the gas rings. Still not clear how it could get where it was unless it was there during assembly. Too big to fit past rear of pin.
New to AR, Took the new SFAR out first time after a cursory cleaning. I did not take bolt apart (I know I know)
On shot 7 no primer contact tried once more same thing just a tiny barely visible scratch.
Pulled bolt, could see something brass or copper not round flush in the fire pin hole...
