Luth-AR .750 Gas Block – AR-15 Standard Profile Barrels

The Luth-AR .750 Gas Block is a replacement gas block designed for AR-15 rifles with standard .750-diameter barrel profiles. This component regulates gas flow from the barrel into the gas tube, cycling the bolt carrier group. Whether you're replacing a worn factory block or upgrading to a more robust setup, this gas block provides reliable function for mid-length and carbine-length gas systems.

Constructed from steel with a black finish, the Luth-AR .750 Gas Block features a low-profile design that fits under most free-float handguards. Installation requires removal of the existing gas block and securing this unit with set screws—basic gunsmithing tools and experience recommended. Includes set screws for mounting.
