CMC Triggers AR-15 Gas Tube 11.75" Rifle Length Black Nitride

The CMC Triggers 11.75" rifle-length gas tube delivers consistent gas pressure regulation for AR-15 platforms chambered in .223/5.56 NATO. This 304 stainless steel component features a black nitride finish that resists corrosion while maintaining precise gas flow dynamics required for reliable cycling.

What Makes This Different

Unlike standard carbon steel gas tubes that can corrode over time, this 304 stainless steel construction provides superior longevity and maintains dimensional stability under extreme heat cycles. The black nitride coating adds an extra layer of protection against fouling buildup while reducing maintenance requirements. CMC Triggers manufactures this component to mil-spec dimensions with tighter tolerances than many factory alternatives.

Key Features

• 304 stainless steel construction resists corrosion and heat stress
• Black nitride finish reduces fouling and simplifies cleaning
• 11.75" rifle length optimized for 20" barrel configurations
• Mil-spec .750" diameter fits standard gas blocks
• Precision-formed tube maintains consistent internal diameter
• Compatible with standard AR-15/M16 upper receivers
• Drop-in replacement for factory gas tubes

This gas tube performs reliably across temperature extremes from sub-zero conditions to rapid-fire scenarios where barrel temperatures exceed 400°F. The stainless steel material maintains structural integrity under sustained firing schedules that would degrade lesser materials. Competitive shooters and law enforcement professionals rely on this component's consistent gas delivery for match-grade accuracy and function.
