The Dead Air KeyMicro Muzzle Brake (brand part no. DA110) is a short, lightweight, single-port brake cut to a 1/2-36 thread with a 9mm bore, suited to a variety of pistol-caliber platforms. Designed for use with Dead Air’s KeyMicro Adapter, it functions as a minimalist standalone brake even without the adapter installed, and the two work together as the ultimate low-profile mounting platform. The KeyMicro uses the same mounting technology found in Dead Air’s industry-proven KeyMo system, and it’s also compatible with the KeyMo Adapter.
