Luth-AR .936 Gas Block – AR-15 Low-Profile Steel

The Luth-AR .936 Gas Block is a low-profile steel block designed for AR-15 platforms with .936-diameter barrels. This gas block regulates gas flow from the barrel into the gas tube, cycling the bolt carrier group. Upgrading to a quality gas block ensures reliable function and can reduce gas leakage that causes erratic cycling or buildup in the receiver.

Constructed from steel with a matte black finish, this block mounts securely with set screws. Installation requires basic armorer tools and careful alignment—proper headspacing and gas tube alignment are critical. A torque wrench and gas block alignment jig are recommended. Not compatible with barrels of other gas block diameters.
