Sons of Liberty Gun Works looks at the bolt carrier group as the heart of the gun. If the gas port is the lungs, then the bolt carrier group is the heart. Its what drives the entire gun. If you look at the AR platforms cycle of operations, everything happens around the bolt carrier group. Locking, unlocking, extracting, and ejecting, all of it begins with the bolt carrier group. Sons of Liberty Gun Works Bolt Carrier Group is a premium BCG that leaves no stone unturned when it comes to quality control and performance.
