The GunTec USA Pistol-Length Gas Tube (brand part no. PTUBE) is a 6.625-inch 304 stainless steel gas tube sized to run in a pistol-length AR-15 gas system. It is a direct factory-length replacement, so it drops into a pistol-length gas block and carrier key without fitting or trimming. Builders swapping a bent, pitted, or worn gas tube during an AR pistol build or refresh get a correctly dimensioned part instead of guessing at length. The 304 stainless construction resists corrosion better than standard carbon steel over years of firing.
