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

The Dead Air Xemax muzzle brake (DA153) is a purpose-built device for large-bore .338-caliber rifles that uses Dead Air’s Xeno Mounting Technology to maintain concentric, repeatable bore alignment. The brake’s single-port design vectors gas outward and upward to reduce dust signature and manage felt recoil. When paired with the appropriate Xemax adapter and compatible silencers, it is intended to improve suppressor consistency and service life.

This muzzle brake is engineered for shooters who need a robust, repeatable muzzle device for large-caliber precision and suppressor-equipped systems. It is particularly suitable for long-range precision applications and for use on big-bore bolt-action rifles or large-caliber MSRs where control of recoil and dust signature matters.
