The Dead Air Xeno Pistol Wee Brake in 1/2-28 (Dead Air part no. DA125) is a 9mm-bore muzzle device and part of the Xeno family of muzzle devices. Dead Air Silencers designed it as a quick-detach mounting option with pistol-caliber subguns in mind. It is machined from 4140 heat-treated alloy steel with a black nitride finish, which keeps it short and light at the muzzle. Pair it with the appropriate Xeno adapter to run a suppressor such as the Wolfman, Ghost, Primal, Nomad or Sierra 5.

Key Specifications

• The through bore is 9mm, the bore size Dead Air gives for every thread version of this brake.
• The listed weight for this version is 2.40 ounces, light enough to leave a pistol-caliber carbine balanced.
• Overall length is 1.575 inches, Dead Air’s figure for the Wee Brake.
• The body is 4140 heat-treated alloy steel, a hard steel that stands up to repeated mounting.

• It is a quick-detach mounting option designed with pistol-caliber subguns in mind.
