The Rosco Manufacturing Gas Tube (brand part no. ROS-GT-C-001) is a carbine-length AR-15 gas tube finished with Rosco’s Melonite Black Nitride treatment. The nitride process increases corrosion resistance, wear resistance, and fatigue strength over a standard untreated gas tube, while also giving it a clean black cosmetic finish that matches a nitrided or black-finished upper. Because it is more durable than a standard tube, it holds up well to the heat and carbon fouling that build up under a handguard over thousands of rounds. This is a straightforward, direct-fit upgrade for anyone building or refreshing a carbine-length AR-15 gas system.
