Dead Air Armament | KeyMo Muzzle Brake

The KeyMo Muzzle Brake reduces felt recoil and muzzle rise with genuinely less concussion than a traditional brake, built from 4140 heat‑treated alloy steel with a black nitride finish and a sealed taper design that sits forward of the locking channels -⁠- meaning the suppressor detaches cleanly instead of carbon‑locking to the mount after a hard range session. Available across 1/2x28, 5/8x24, 3/4x24, M18x1, and M18x1.5 thread patterns in .30 and .338‑caliber bores, with the two smallest sizes pre‑drilled at the 6 o'clock position for pin‑and‑weld installs. Ships with a shim kit for proper timing -⁠- a brake that does real recoil‑reduction work whether or not you ever mount a can to it.
