Sons of Liberty Gun Works LIBERTY Gas Block .750 – AR-15 Mid-Length and Carbine-Length Systems

The Sons of Liberty Gun Works LIBERTY Gas Block is a precision-machined, low-profile gas block designed for AR-15 platforms with .750-inch diameter barrels. This component regulates gas flow from the barrel into the gas tube, cycling the bolt carrier group during semi-automatic operation. Upgrading to a quality gas block ensures reliable cycling, reduces gas leakage, and improves overall system performance—especially important for shooters running suppressed or seeking consistent function across different ammunition loads.

Machined from steel with a durable finish, the LIBERTY gas block features a set-screw attachment system for secure, repeatable installation on standard .750" barrel journals commonly found on mid-length and carbine-length gas systems. Installation requires basic armorer-level tools and familiarity with AR-15 assembly—torque specs should be followed carefully to prevent barrel damage. The low-profile design sits flush under most free-float handguards.
