Sons of Liberty Gun Works engineered their 5.56 NATO Full Auto Bolt Carrier Group with the understanding that this component functions as the gun’s core. Like lungs processing air, the gas port feeds the system—but the bolt carrier group is what pumps it forward. Every mechanical action in the AR platform revolves around this assembly: locking into battery, unlocking after firing, extracting spent casings, and ejecting them downrange all originate from the bolt carrier group’s operation.
