bolt carrier
A bolt is the part of a repeating, breech-loading firearm that blocks the rear opening (breech) of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The extractor and firing pin are often integral parts of the bolt.
In gas-operated firearms, the bolt itself is housed within the larger bolt carrier group (BCG), which contains additional parts that receives rearward push from the gas piston.
The slide of a semi-automatic pistol is a form of bolt, as it contains the same parts and serves the same functions.
