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. Optimized for use on .33 Caliber (including 33 XC and .338 Lapua Mag 8.6 Blackout) Bolt Action Rifles and.45 Caliber (.45-70 .450 Bushmaster) Lever-Action and big-bore MSRs the Xemax system is perfectly paired with the our new Nomax 33 Silencer for the ultimate big-bore shooting experience. Furthermore Dead Air Primal silencer owners will also be able to enjoy the benefits of Xemax by simply installing the Xemax adapter on their silencer and the Xemax muzzle brake on their host weapon. All of the Xemax Muzzle Brakes do require "timing" and come with the appropriate Shims to do so. NOTE: Please consider caliber and bore limitations of the suppressor when mounting the Xemax adapters and mounts.
