TacFire MAR011 .750 Low Profile Gas Block and Mid-Length Gas Tube Combo - Pinned

The TacFire MAR011750GB is an assembled .750 low profile gas block and mid-length gas tube combination built for AR-15 and M16 platform builds. This combo ships with the gas block and gas tube pre-assembled and pinned together, cutting installation time and getting the upper together faster than sourcing and fitting each component separately.

The low profile gas block is machined from steel with a black finish and is sized for the standard .750" gas journal found on most AR-15 barrels. Its low profile footprint keeps the unit tight to the barrel so it tucks cleanly under free-float handguards, drop-in handguards, and slim M-LOK and KeyMod rails without clearance issues. The included mid-length gas tube is matched to mid-length gas system barrels, providing reliable cycling and smooth operation for a standard rifle or pistol build.

Installation is straightforward for anyone familiar with the AR-15 upper: the assembled unit seats into the gas block journal on the barrel, the tube routes through the upper receiver gas port, and the included pin locks the gas block to the barrel so it stays put under recoil and field use. This is a budget-friendly, no-frills solution for builders assembling a fresh AR-15, replacing worn gas system components on an existing rifle, or simply wanting a pre-pinned combo for a quicker build.
