Dead Air Xemax Muzzle Brake | .338 Cal | M18X1 | DA153

The Dead Air XEMAX muzzle brake (DA153) is a threaded muzzle device engineered for big-bore .338-class rifles. It employs Dead Air’s Xeno mounting taper for self-aligning concentricity, and a single-port brake geometry that vectors gas outward and upward to reduce ground dust and felt recoil. The XEMAX family is designed to work with Dead Air silencers (Nomaxx 33 and Primal with adapter) to help preserve suppressor life and maintain performance consistency.

Typical applications include precision long-range shooting and large-caliber field use where suppressor pairing and recoil management are priorities.
