I had a stag upper that I sent to them to change the railed gas block to a standard fsp. When I got it back I noticed they sent me a complete brand new upper instead of just changing the gas block. New bolt carrier group, barrel, rail and everything.
Anyway I had a new unused bcm bcg that I was going to use for a build, but that project is cancelled for now. I didn't like the staking on the gas key of the new stag carrier (my old stag carrier was good not great but acceptable, the new one looks weak on one side) so I want to used the bcm bolt carrier group. Do I need to check head spacing?
The two bcgs look identical aside from the staking. Both are m16 carriers.
