TacFire MAR009-750GB Low Profile .750" Gas Block Black Nitride AR-15 Pistol Length

The TacFire MAR009-750GB is a low profile .750" gas block machined from carbon steel and finished in a durable black nitride coating. Engineered for the AR-15 pistol-length gas system, this compact gas block secures directly to the barrel journal with the included mounting pin, leaving a clean, snag-free silhouette that sits comfortably under free-float handguards.

The .750" outside diameter matches standard AR-15 pistol-length barrel journals, and the pinned mounting arrangement locks the block solidly in place during firing. The black nitride finish provides strong wear and corrosion resistance, while the carbon steel body adds the rigidity needed for dependable cycling with both suppressed and unsuppressed builds.

Installation is straightforward: simply press the gas block onto the barrel journal, align the gas tube hole, and drive in the supplied pin. Sized specifically for the pistol-length gas system on the AR-15 platform, the TacFire MAR009-750GB is a direct drop-in component for pistol-length builds and an excellent replacement for worn factory gas blocks on existing rifles.

Whether you are assembling a new AR-15 pistol build or rebuilding a worn upper, the TacFire MAR009-750GB offers a reliable, budget-friendly gas block that delivers clean fitment and long-lasting performance.
