Rosco Manufacturing Melonite Gas Tube Mid-Length Black Nitride

The Rosco Manufacturing Melonite Mid-Length Gas Tube is a replacement AR-platform mid-length gas tube designed for builders refreshing a worn factory tube or assembling a mid-length gas system build. Machined to standard mid-length dimensions and finished in Rosco's Black Nitride (Melonite) coating, this tube brings the durability benefits of a nitrided steel surface to your upper receiver gas system.

Rosco's Black Nitride finish creates an extremely hard surface that delivers measurable increases in corrosion resistance, wear resistance, and fatigue strength while giving the gas system a clean matte-black cosmetic appearance. As a direct-fit component for any standard mid-length AR gas system, this Melonite gas tube from Rosco Manufacturing is a quality choice for both replacement and custom-build applications.
