Dead Air XEMAX Muzzle Brake .338 5/8-24

The Dead Air XEMAX muzzle brake is a purpose-built muzzle device for .338-caliber firearms using a 5/8-24 thread pattern. The XEMAX system uses an inherently concentric, self-aligning taper to support repeatable bore alignment when paired with compatible adapters and suppressors. Finished in nitride and constructed from alloy steel, this muzzle brake is intended for large-bore rifle platforms where robust construction and consistent alignment are priorities.

The XEMAX muzzle brake brings Dead Air’s Xeno mounting philosophy to large-bore platforms, providing a durable, repeatable interface for muzzle devices and compatible suppressors. Its single-port brake geometry is designed to direct gas and reduce dust signature at the muzzle, while the robust construction and nitride finish are intended for long-term field use. For shooters running .338-class rifles with compatible mounting hardware, the XEMAX offers a purposeful solution for consistent alignment and serviceable construction.
