The Guntec USA Mid-Length Gas Tube (brand part no. MTUBE) is an 11.75-inch gas tube machined from 304 stainless steel and sized for AR-15 mid-length gas systems. It is a direct, factory-style replacement for anyone building a mid-length upper or swapping out a bent, pitted, or damaged factory gas tube. The 304 stainless construction resists the corrosion and carbon buildup that a plain steel tube develops over time in the gas system’s high-heat environment.
