Dead Air Xeno Omni Brake | M14x1RH | .30 Cal | DA139

The Dead Air Xeno Omni Brake is a compact muzzle brake designed to function well as a standalone device and to interface precisely with the Xeno Adapter-equipped suppressor. Its shorter length and lock-up positioning minimize focused erosion on suppressor baffles, extending service life while preserving sound performance. Constructed for durability, the brake provides repeatable mounting and a solid return to zero in suppressed rifle builds.

Recommended applications include precision shooting and general range use where repeatable suppressor attachment and reduced baffle wear are priorities.
