The Guntec USA Gas Tube is a rifle-length AR-15 gas tube machined from 304 stainless steel, brand part number RTUBE. Stainless construction gives it better corrosion resistance than a standard carbon-steel tube, which matters most on a tube that sits directly in the path of hot combustion gas on every shot. At 15.25 inches, it is sized specifically for rifle-length gas systems, making it a straightforward, more durable replacement for a worn or damaged factory tube on a full rifle-length AR-15 build.
