Dead Air DA139 Xeno Muzzle Device M14x1 RH Thread Black Nitride

The Dead Air DA139 Xeno muzzle device delivers rapid suppressor attachment with the proven Xeno mounting system. This black nitride-finished device provides the foundation for Dead Air's quick-detach suppressor lineup while functioning as an effective muzzle brake when used standalone.

What Makes This Different

Unlike traditional muzzle devices that serve only one purpose, the DA139 Xeno combines muzzle brake performance with suppressor mounting capability. The proprietary Xeno interface locks suppressors in place with a simple quarter-turn, eliminating the timing issues and thread wear associated with direct-thread systems. Heat-treated 4140 alloy steel construction withstands repeated suppressor mounting cycles without degradation.

Key Features

• Xeno quick-detach mounting system for rapid suppressor attachment
• 4140 heat-treated alloy steel construction for maximum durability
• Black nitride finish resists corrosion and reduces maintenance
• M14x1 right-hand threads fit standard .308/7.62 rifle barrels
• Functions as standalone muzzle brake when suppressor not attached
• Compatible with Dead Air Sandman, Nomad, and Primal suppressors
• Precise manufacturing ensures proper suppressor alignment

Field testing demonstrates consistent point-of-impact shifts when transitioning between suppressed and unsuppressed configurations. The device maintains zero retention across multiple mounting cycles, critical for precision shooting applications. Law enforcement and military users benefit from the rapid transition capability during tactical scenarios where suppressor use may vary by mission requirements.
