What kind of ammo were you using? Cheap 223 steel cased? It sounds like the BCG just needs to be broken in. I would clean and lube the BCG properly first. Then hand cycle the carrier with the charging handle 100+ times to let the bolt and carrier bed itself into the upper smooth out some of the surfaces that rub and rotate against other parts. Then when you take it out, shoot so equality 556 rounds through it as it will have more power to push the BCG all the way back so it'll strip a round off the mag as it should. You can also shoot one round per mag to see if the carrier is held ack on the last round. If it does, them you're good to go.
