The Dead Air KeyMo Zero Mount .578×28 (Dead Air part no. DA322) is a lightweight, minimalist quick detach muzzle mount. Dead Air says the shorter size reduces how far it enters the blast chamber, which helps sound performance and keeps weight down. It is cut for .578×28 with a .45 bore, and the suppressor can be removed without carbon locking onto the mount. It is compatible with all Dead Air KeyMo and KeyMicro adapter equipped silencers. It is a good fit for .45 caliber hosts that use the .578×28 thread.
