The Dead Air Armament Xeno Omni Muzzle Brake DA124 is a 5/8x24 threaded .30 caliber bore muzzle device for shooters using the Dead Air Xeno mounting system. It works as an effective stand-alone muzzle brake and also serves as a lightweight suppressor mounting interface when paired with a compatible Xeno adapter-equipped suppressor.

Dead Air designed the Xeno system around repeatability, durability, and a compact lock-up. The Xeno Omni Brake uses a taper-mount design with left-hand threads at the suppressor interface, helping reduce the chance of the adapter unthreading from the suppressor during removal.

Built for the Xeno Mounting System: The DA124 Xeno Omni Brake is part of Dead Air’s Xeno family of muzzle devices. It is intended for use with compatible Dead Air Xeno adapters and suppressors that accept the appropriate Xeno mounting system.

Ideal for Common .30 Caliber Rifle Threads: The 5/8x24 thread pitch is commonly used on .30 caliber rifle barrels, including many .308 Winchester, 7.62 NATO, 6.5 Creedmoor, and .300 Blackout barrels. Always confirm your firearm’s actual thread pitch before installation.

Short, Durable, and Suppressor-Friendly: The shorter lock-up position helps keep the muzzle device from sitting deep into the suppressor blast chamber, which can help reduce focused baffle erosion while keeping the overall mounting system compact.

4140 HT Steel and Black Nitride Finish: Dead Air uses nitrided 4140 HT alloy steel for hardness, corrosion resistance, and durability under hard use. The black nitride finish also supports easier cleaning of carbon and copper deposits.

Important Fitment Note: This DA124 model has 5/8x24 barrel threads and a .30 caliber bore. Always confirm your firearm’s barrel thread pitch, bore clearance, suppressor compatibility, and alignment before installation or suppressor use.
