Dead Air Xeno Xero Muzzle Brake/Adapter, 9mm

The Dead Air Xeno Xero (part no. DA143) is a 9mm muzzle brake and mounting adapter threaded 9/16×24 that uses Dead Air’s self-aligning Xeno taper system for consistent, repeatable bore alignment. Dead Air Silencers built it to work as a standalone brake or as the mounting adapter for a compatible Dead Air silencer, and it ships with the shims needed to time it correctly.

Key Specifications

• Uses Dead Air’s self-aligning Xeno taper system for consistent, repeatable bore alignment.
• Threaded 9/16×24 RH, sized for 9mm hosts.
• Works as a standalone muzzle brake, vectoring gas outward and upward to cut ground dust and felt recoil.
• Doubles as a mounting adapter for a compatible Dead Air silencer, helping extend the suppressor’s service life.
