Which process releases the locking lugs from the bolt face on the weapon?

The process that releases the locking lugs from the bolt face on the weapon is unlocking. This is a critical phase in the operation of a firearm, as it occurs after the firing of a round. During firing, the locking lugs engage to ensure that the bolt remains locked in place, which is essential for safety and proper function while the round is being discharged.

Once the shot is fired and the bullet has exited the barrel, the unlocking process begins as the bolt carrier group moves rearward. This movement allows the locking lugs to disengage from the barrel extension, thus freeing the bolt from the locked position. The subsequent actions, such as extracting the spent cartridge case and ejecting it, depend on this initial unlocking step. Therefore, understanding the importance of the unlocking process helps clarify the mechanics of how a firearm operates.
