CMC Triggers 81622 AR-15/AR-10 Gas Tube Carbine Length 9.79" 304 Stainless Steel - Black Nitride

The CMC Triggers 81622 is a carbine-length gas tube built for AR-15 and AR-10 platforms. Precision machined from 304 stainless steel and finished in a durable black nitride coating, this tube is designed to deliver reliable cycling and excellent corrosion resistance on direct-impingement AR builds. At 9.79" in overall length, it is correctly sized for a standard carbine-length gas system, making it an ideal direct replacement or upgrade for worn factory tubes.

The black nitride surface treatment penetrates the steel to create a hard, low-friction finish that resists wear and helps the tube shrug off heat and carbon that build up during sustained fire. As an AR-15/AR-10 component, the tube is dimensionally matched to standard upper-receiver gas blocks and is straightforward to install with basic armorer's tools.

Proudly made in the USA, this CMC Triggers gas tube is a quality component for a new build, a parts refresh, or a complete gas-system replacement.
