Dead Air Xeno Deadair Da125 Xeno Pistol Wee Brake 1/2-28

The Dead Air Xeno DA125 Pistol Wee Brake is a compact QD muzzle device built for PCCs (pistol caliber carbines) and short-barreled hosts that demand minimal footprint without sacrificing durability. Threaded 1/2-28, this brake pairs seamlessly with Dead Air suppressors via the appropriate Xeno adapter—including the Wolfman, Ghost, Primal, Nomad, and Sierra 5—and the left-hand threads lock down with confidence and repeatability. If you're running a silencer on a subgun and want a mounting solution that delivers precision accuracy and hard-use reliability in a truly lightweight package, the Xeno system cuts through the noise.

Dead Air engineered the Xeno line around a few core principles: repeatable accuracy, durability, and minimal length and weight addition to your can. The 9mm bore accommodates pistol-caliber loads, and the design accounts for suppressors with smaller blast chambers across the market. That forward-thinking approach means your rig stays balanced and your suppressor performs as intended. The large taper, accessible tool features, and left-hand thread geometry all work together to lock your mounting interface tight, shot after shot.

Material matters when your threads see repeated use. This brake is machined from 4140 hardened steel and finished in black nitride—a process that hardens the surface and resists corrosion without the galling risk that uncoated 17-4 stainless can create. Translation: cleaner disassembly, less risk of cross-threading, and threads that stay true for the life of the gun. Scouring carbon and copper deposits becomes a straightforward job, and you won't worry about damaging the interface during routine maintenance.

At 2.40 ounces and just 1.575 inches long, the Xeno DA125 adds almost nothing to your setup's profile or balance—a real asset on a lightweight PCC where every tenth of an ounce and half-inch counts. Pair it with your Dead Air suppressor and the matching Xeno adapter, and you've got a mounting system engineered for both precision and abuse.
