Sons of Liberty Gun Works Nickel Teflon 5.56mm & .300BLK Carpenter 158 OCKS Screws Deep Engraved Bolt Carrier Group SOLGW-BCG556-NTC

The Sons of Liberty Gun Works Nickel Teflon Bolt Carrier Group is a professional-grade internal component designed for maximum lubricity and ease of maintenance in high-volume firing scenarios. The Nickel Teflon coating provides a smooth, low-friction surface that resists carbon fouling, making it particularly effective for suppressed AR-15 platforms. This BCG is built with a Carpenter 158 steel bolt and an 8620 steel carrier, all secured with high-torque OCKS screws and deep mechanical staking to ensure the gas key remains permanent under extreme heat and pressure.
