TacFire Assembled Gas Block Features The TacFire Assembled Gas Block ships as a complete ready to install assembly that pairs a low profile .750 gas block with a matching pistol length gas tube. Because it arrives pre-assembled builders save the time and hassle of sourcing and fitting a gas tube separately cutting down on build errors and misalignment. The low profile design sits flush under a free float handguard letting the rifle run a slimmer more ergonomic rail without a bulky front sight base in the way. A pistol length gas system is a common choice on short-barreled AR pistol builds where space under the handguard is limited. Finished in black the TacFire gas block and tube assembly matches the vast majority of factory and aftermarket AR-15 components without drawing attention to itself. The gas block clamps securely to a .750 diameter barrel delivering reliable gas flow to cycle the action shot after shot. Builders assembling a pistol length AR upper from scratch get a drop-in solution that takes the guesswork out of gas system fitment. The TacFire Assembled Gas Block and pistol length gas tube is for sale at GrabAGun for anyone finishing an AR-15 build with a clean low profile gas system.
