The CMC Triggers low profile gas block comes with a ton of features that set it apart from the competition. This AR-15 gas block is made from 17-4PH stainless steel with a black Nitride finish. This type of steel is designed for use in a wide range of applications involving containment of high pressure, making it the ideal material for a gas block. The Nitride finish provides additional wear and corrosion resistance for long lasting performance. The low-profile design is compatible with a wide range of free floating handguards with internal diameters greater than 1.35 inches, so you can fully customize your rifle. The narrow one-piece gas block fits barrels with .750” outside diameters at the gas port and is attached via the robust set screw method. It is time to upgrade your AR-15 and this CMC Triggers low profile gas block is an important step in the process.
