SONS OF LIBERTY GUN WORKS

158 Carpenter SP / HPT / MPI Complete 5.56 Bolt Carrier Group

We look 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. It’s what drives the entire gun. If you look at the AR platform’s cycle of operations, everything happens around the bolt carrier group. Locking, unlocking, extracting, ejecting…all of it begins with the bolt carrier group.
