TacFire MAR008750GB Low Profile Gas Block with Carbine Gas Tube .750" AR-15 Black Steel

The TacFire MAR008750GB is an AR-15 low-profile clamp-on gas block factory-assembled with a carbine-length gas tube secured in place by a roll pin, giving builders a ready-to-install gas system component for barrels with a .750" gas journal.

Machined from steel and finished in black, this unit clamps to the barrel with included set screws and ships with the tube pre-installed and pinned to the block, so no separate fitting or alignment is needed at the bench. The low-profile design tucks cleanly beneath most free-float handguards, replacing the factory gas block and tube pairing in a single assembly.

Built for the AR-15 platform and any barrel profile cut for a .750" diameter gas block seat, this is a straightforward replacement or build component for assembling or servicing a carbine-length gas system.
