Dead Air XEMAX Muzzle Brake Features The Dead Air XEMAX Muzzle Brake is built on Dead Air s Xeno Mounting Technology scaled up for big-bore .33 and .45 caliber rifle chamberings featuring an inherently concentric self-aligning taper system that delivers consistent bore alignment and repeatability of results across every suppressor installation. As a standalone device the single-port brake design vectors gas outward and upward for meaningful recoil reduction and minimized ground dust dispersion keeping the shooter s sight picture clear during rapid follow-up shots. When used with the Nomaxx 33 or Dead Air Primal suppressor via the Xemax adapter the system is designed to optimize suppressor performance consistency and maximized suppressor service life on big-bore platforms. The self-aligning taper system ensures the suppressor indexes to the same concentric position on every installation providing repeatable point-of-impact retention and reliable baffle clearance across .338 Lapua Mag and compatible big-bore chamberings. At 2.06 and 2.94 oz. the XEMAX Muzzle Brake adds minimal length and weight to the muzzle end while providing the full benefit of Xemax mounting technology. Timing is required and appropriate shims are included for a properly indexed installation.
