The Dead Air DA101 KeyMo Muzzle Brake is a 1/2″-28 threaded quick-detach device compatible with AR-15 rifles chambered in 5.56mm NATO. Constructed from 4140 HT alloy steel with a black nitride finish, this muzzle device measures 2.82″ in overall length and weighs 4.42 oz. The DA101 comes with a pre-drilled hole for pin and weld at the 6 o’clock position, making it compatible with both direct-thread and permanently attached installations.
The KeyMo Muzzle Brake serves as your gateway to silence—when you’re ready for peace and quiet, use the KeyMo brake to quickly attach your KeyMo equipped suppressor to your rifle. The KeyMount brake can be used to quickly attach your Sandman-L, Sandman-S, Sandman-K, or KeyMo equipped Nomad-30 or Primal silencer. The sealed taper design sits forward of the KeyMo locking channels, allowing the suppressor to be easily removed without carbon-locking onto the mount.
When shooting unsuppressed, it reduces felt recoil and muzzle rise with less concussion than traditional brakes. The KeyMo brake comes with an included shim kit for timing your muzzle device, ensuring proper alignment during installation. Whether you’re upgrading to suppressed shooting or simply want premium recoil management on your 5.56 rifle, the Dead Air KeyMount delivers professional-grade performance.
