Great GIF. So the BCG releases the hammer just as the BCG locks into battery?
In the AUTO mode on a select-fire gun, the bottom leading edge of the tail on the bolt carrier trips the AUTO sear to release the hammer right after the bolt has locked into the extension.
It acts as the timing mechanism to allow controlled automatic fire on a locked breech.
