The Dead Air KeyMo Muzzle Brake (brand part number DA160) is a .45-caliber muzzle device cut to a .578-28 thread pattern, built for Dead Air’s KeyMo suppressor mounting system on big-bore hosts. Run bare, it works as a standard brake to cut recoil and muzzle rise on a .45-caliber rifle; it also doubles as the mounting interface for KeyMo-compatible Dead Air suppressors, so the same host can run bare or suppressed on one thread standard.
