TacFire MAR010750GB .750" Low Profile Gas Block Phosphate Steel Black with Rifle Pin

The TacFire MAR010750GB is a low-profile gas block built for AR-15 pattern rifles with a .750" gas journal. Machined from heat-treated steel with a black anti-reflective finish, this compact clamp-on gas block channels propellant gas from the barrel to the gas tube while keeping a slim cross-section that fits inside most free-float handguards.

This is the .750" diameter configuration of TacFire's low-profile gas block, the standard journal size for most AR-15 barrels. The MAR010750GB ships as a complete combo package with the gas block and a rifle-length roll pin, giving you everything needed to install it on a standard gas block journal on an AR-15 upper assembly.

Key features:

• Low-profile design that clears free-float handguards
• .750" gas journal diameter for standard AR-15 barrels
• Heat-treated steel construction
• Black anti-reflective finish
• Includes rifle-length roll pin for installation
• Drop-in replacement or upgrade for worn factory AR-15 gas blocks
