It appears they are using an Armalite BCG.
The firing pin retaining pin is like that of an Armalite, as is the firing pin. That being spring loaded.
The Brownells BCG based upon a DPMS gen 1 BCG fit fine with the stock bbl from BCL, but I did not do any firing with it.
It wouldn't work with the Criterion bbl so I went back to the stock BCG and it is fine.
I picked up an extra BCL BCG so I can do some fooling around with it.
Am thinking of a new faxon bcg and barrel which should fit but not sure if I'm gonna run into trouble. Where did you get the extra bcl bcg?
