CMMG 55DA196 AR-15 Rifle Length Gas Tube Kit Stainless Steel

The CMMG 55DA196 AR-15 Rifle Length Gas Tube Kit delivers precision-engineered gas system components for reliable cycling in standard and custom AR-15 builds. This stainless steel construction resists corrosion while maintaining consistent gas flow across thousands of rounds.

What Makes This Different

Unlike basic gas tubes that use standard steel construction, this CMMG kit features 416 stainless steel that withstands extreme temperatures and corrosive environments without degradation. The rifle-length gas system reduces bolt carrier velocity compared to carbine systems, resulting in smoother cycling and reduced wear on internal components. Each tube undergoes precision manufacturing to maintain optimal gas port alignment and flow rates.

Key Features

• 416 stainless steel construction resists corrosion and heat stress
• Rifle-length gas system (15+ inch gas tube) for reduced bolt speed
• Precision-machined gas port maintains consistent diameter tolerances
• Compatible with standard AR-15/M16 gas blocks and bolt carriers
• Includes gas tube roll pin for secure installation
• Fits barrels with rifle-length gas port positioning
• Smooth interior finish promotes consistent gas flow

This gas tube kit performs reliably across temperature extremes from -40°F to 140°F, making it suitable for competitive shooting, hunting, and tactical applications. The rifle-length gas system reduces felt recoil and muzzle rise compared to shorter gas systems, improving follow-up shot accuracy. Stainless steel construction maintains dimensional stability through rapid heating and cooling cycles during sustained fire.
