The CMC Triggers 81625 AR-15 nitride gas tube is a critical but often-overlooked component in any AR build. While plenty of shooters focus on triggers, barrels, and optics, the gas tube is the workhorse that actually cycles your rifle—and it deserves the same attention to quality. This 15.16" tube is machined from 304 stainless steel and finished with a black nitride coating that resists corrosion and stands up to the wear that comes with regular shooting and cleaning. Whether you're building a new rifle, replacing a worn tube, or upgrading an older AR, this CMC gas tube delivers the reliability you need without the guesswork.
CMC Triggers manufactures this gas tube right here in the USA, meaning you're getting a part made to domestic standards with traceability and quality control behind it. The nitride finish isn't just cosmetic—it's a functional treatment that hardens the steel surface and protects against rust and fouling buildup. For shooters who run suppressed rifles, shoot in adverse weather, or simply want a gas tube that'll last through thousands of rounds without degradation, this is the kind of component that pays for itself in reliability and uptime.
The 15.16" length covers rifle-length gas systems, common in full-size AR-15 builds and precision rifles. If your AR calls for a different gas tube length—pistol, carbine, mid-length, or intermediate—CMC offers those too, so you can find the exact fit your rifle needs.
