The Dead Air Armament Keymo Deadair Da163 Keymo Muzzle Brake is a precision muzzle device engineered for shooters who demand a standardized, repeatable platform for sound suppression and recoil management. Built around Dead Air's proven Keymo quick-detach system, this .46 11/16-24 threaded brake delivers the adaptability serious shooters need—swap suppressors or run it standalone without losing zero or worrying about thread pitch compatibility.
Dead Air Armament has built a reputation for robust, repeatable engineering across their suppressor ecosystem, and the Keymo brake is no exception. The standardized 11/16-24 threads make this brake a plug-and-play solution if you're already invested in Dead Air's suppressor lineup or planning to be. Whether you're setting up a precision rifle for range work, hunting, or tactical applications, a quality muzzle brake anchors the entire system—managing recoil impulse and keeping the bore stable shot to shot.
If you run or plan to run a Dead Air suppressor, the Keymo interface eliminates the guesswork and mechanical slop that can creep into traditional fixed suppressors. You get the same attachment point every time, which means superior point-of-impact consistency across configurations. That's the kind of foundation serious shooters build on.
The Da163 is threaded 11/16-24, a common rifle thread pitch. Confirm your rifle's muzzle thread pitch (11/16-24) before purchase to ensure compatibility.
Yes. The Keymo interface is Dead Air's standardized quick-detach platform, designed to work seamlessly with Dead Air suppressors that feature Keymo mounting.
Yes. The Keymo Da163 functions as a standalone muzzle brake and can be used independently of a suppressor.
