The Sons of Liberty Gun Works Liberty Gas Block is machined from 4140 steel — selected to match the thermal expansion properties of a CrMoV barrel — ensuring a consistent, tight fit throughout the full operating temperature range. The .750" bore diameter fits standard-profile AR-15 barrels and the gas block seats directly on the gas block shoulder, eliminating the handguard cap gap for a more secure, stable mount. Knurled-head set screws engage a dimpled barrel surface to lock the gas block firmly in place without staking. An ideal low-profile gas block for any free-float handguard build requiring a reliable, no-frills component.
