Sons of Liberty Gun Works .750 Gas Block

Build your next duty, defensive, or competition AR rifle on an unyielding foundation with the Sons of Liberty Gun Works Liberty Gas Block (.750"). Engineered by SOLGW to meet the rigorous demands of hard-use firearms, this low-profile gas block delivers reliable gas routing, tight tolerances, and uncompromising durability. Machined from 4140 heat-treated steel and protected by a hard-wearing black nitride finish, it is built to withstand extreme thermal expansion, carbon fouling, and high sustained rates of fire without erosion or gas leakage.

Designed to sit flush against the gas journal shoulder of standard .750-inch barrels, the Liberty Gas Block ensures precise alignment over the gas port for consistent cycling. It comes outfitted with heavy-duty knurled set screws that bite into the barrel journal to prevent backing out under heavy recoil. For ultimate peace of mind and duty-grade security, the gas block is also pre-machined and ready to be cross-pinned to your barrel, making it an ideal choice for custom rifle builders and armorers alike.
