The AR-15 Bolt Carrier Group (BCG) is a critical component of the rifle's functioning, acting as the core of the firearm's gas-operated system. Comprising essential AR-15 parts like the bolt itself, carrier, firing pin, gas key, cam pin, and retaining pin, the BCG is responsible for the cycle of loading, firing, extracting, and ejecting rounds. Its design and construction are paramount for the reliable operation of the AR-15, with materials and coatings varying to enhance durability, reduce wear, and ensure smooth action.
