The Dead Air Xemax is a .338-caliber muzzle brake designed for rifles using 3/4-24 muzzle threads. Its Xeno Mounting Technology uses a self-aligning taper system intended to support consistent bore alignment and repeatable installation.

The single-port design directs gas outward and upward, helping reduce ground-dust dispersion and felt recoil. It is intended for .338-caliber applications, including .338 Lapua Mag, and can be used with compatible Dead Air suppressor systems and adapters.
