The Dead Air KeyMo Muzzle Brake (brand part number DA101) is a .22-caliber muzzle device built for Dead Air’s KeyMo suppressor mounting system, threading directly onto a 1/2×28 barrel. Run bare, it works as a standard muzzle brake to cut recoil and muzzle rise on a .22-caliber host; it also doubles as the mounting interface for KeyMo-compatible Dead Air suppressors, so you can standardize the same host to run bare or suppressed without changing thread patterns.
