Our Xemax Muzzle brakes and Adapter are Xeno Mounting Technology Made Bigger. The inherently concentric design has a self-aligning taper system for consistent bore alignment and repeatability of results. Made Beefier to handle big bore calibers in .33 and .45 rifle chamberings (with a Primal Silencer), Xemax muzzle brakes can also extend the life of your silencer. When used alone, the single-port brake design of the Xemax vectors gas outward and upward, minimizing ground dust dispersion and reducing felt recoil. Inside a Nomaxx 33 Silencer, Xemax muzzle brakes are designed to provide optimal suppressor performance, consitency, and maximized suppressor life.
