Rosco Manufacturing Gas Tube AR-15 Carbine Length Black Nitride

The Rosco Manufacturing Gas Tube is a precision AR-15 component purpose-built for carbine-length gas systems. Treated with a rugged Black Nitride (Melonite) finish, this gas tube delivers improved corrosion resistance, wear resistance, and fatigue strength over standard stainless or phosphated tubes, making it an excellent drop-in replacement or fresh-build part for any carbine gas system.

Measuring 10" overall with a slim 0.5" x 0.5" profile, the ROS-GT-C-001 seats cleanly under a standard carbine handguard and is designed for use on the AR-15/M4 platform. The Black Nitride finish also gives the tube a deep, low-glare appearance that pairs well with both black and Flat Dark Earth components.

Whether you are completing a new build or swapping out a worn factory tube, the Rosco Manufacturing carbine-length gas tube is a straightforward, high-quality solution engineered for long-term reliability.
