Sons of Liberty: Bolt Carrier Group, 5.56/.300 Blackout, OCKS Screws

Overview

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. 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. For enhanced carrier key security and peace of mind, this BCG comes with the OCKS (Optimized Carrier Key Screws) upgrade. Works for 5.56 NATO, and.300 Blackout cartridges. | Sons of Liberty: Bolt Carrier Group, 5.56/.300 Blackout, OCKS Screws
