Dead Air Xemax Muzzle Brake | .338 | 3/4-24 | DA151

The Dead Air Xemax muzzle brake is engineered for .338-class big-bore rifles and designed around Dead Air’s Xeno Mounting Technology, which uses a self-aligning taper for consistent bore alignment and repeatable results. Its single-port brake layout vectors gas outward and upward to minimize ground dust and reduce felt recoil when used without a suppressor. When paired with Dead Air’s Nomax 33 or a Primal silencer with the Xemax adapter, the system is intended to optimize suppressor performance and prolong silencer life.

Common applications include long-range precision shooting with magnum bolt-action rifles and use on large-bore lever-action or MSR platforms for heavy-caliber field shooting.
