TacFire AR-15 Pistol Length Gas Tube Features The TacFire AR-15 Pistol Length Gas Tube is machined from 304 hardened stainless steel a material chosen for its strength and resistance to the heat and corrosion a gas tube faces cycle after cycle. Consistent gas flow from the tube to the bolt carrier group is critical for reliable cycling and this tube is built to maintain that flow over the life of the rifle. Its silver finish is the natural result of the stainless construction giving it a durable surface that resists the wear a gas tube experiences near the chamber. Sized specifically for AR-15 pistol length gas systems at 5.25 inches this micro gas tube installs by pinning into the front sight base or gas block with no gunsmithing required for a straightforward swap. That makes it a practical choice both for a from scratch AR-15 build and for replacing a damaged or worn factory tube. A single gas tube ships per unit ready to drop into a compatible pistol length upper. The TacFire gas tube gives builders a reliable affordable component for finishing or maintaining an AR-15 pistol length build at GrabAGun.
