The Spike’s Tactical Rifle-Length Gas Tube (brand part number SUGT0M4) is machined from Mil-Spec 304 stainless steel and Melonite coated for greater heat resistance, corrosion resistance, and lower reflectivity than an untreated tube. This is the same gas tube Spike’s installs on its own ST-15 rifles and complete upper receivers, making it a great fit not just for standard .223/5.56 uppers but also for 5.45x39mm builds running corrosive surplus ammunition. It ships complete with a split roll pin.
