The Dead Air Xemax DA151 muzzle brake in 3/4-24 thread (.338LM) is built for shooters running heavy-hitters like .338 Lapua Magnum, .338-378 Weatherby Magnum, 33 XC, and 8.6 Blackout on bolt-action rifles. If you're serious about taming recoil on a genuine magnum cartridge—or planning to run this brake inside a Dead Air Nomaxx 33 or Primal silencer—the Xemax system delivers the precision gas handling and durability you need to shoot accurately and shoot longer.

Dead Air engineered the Xemax with a self-aligning taper system that keeps bore alignment consistent shot to shot, a hallmark of their Xeno Mounting Technology. The single-port design directs gas outward and upward when fired unsuppressed, cutting felt recoil and minimizing ground dust signature. When threaded inside a Nomaxx 33 or paired with a Primal silencer (via Xemax adapter), the brake optimizes gas flow for reliable suppressor performance and extends silencer longevity on these powerful cartridges.

This is a timing brake, so installation requires the included shims to ensure proper alignment on your barrel. At 2.93 ounces and 2.06 inches long with a 1.125-inch diameter, it's proportioned for magnum rifles without excessive bulk. If you're building or upgrading a .338LM precision rifle and want real recoil reduction backed by thoughtful engineering, the Xemax DA151 is a serious choice.
