Dead Air Keymo Deadair Da322 Keymo Zero .578-28 .45 Cal

The Dead Air Keymo Zero is a minimalist quick-detach muzzle device engineered for shooters who run Dead Air suppressors and want a lightweight, repeatable mounting solution. Threaded in .578-28 for .45 caliber applications, this mount delivers the speed and reliability of the KeyMo system in a compact form factor designed to maximize suppressor sound performance while keeping overall weight down.

What sets the KeyMo Zero apart is its approach to simplicity. The shorter profile means less intrusion into your suppressor's blast chamber—a design choice that pays dividends in sound reduction. Like all Dead Air KeyMo mounts, it resists carbon-locking, so your suppressor detaches cleanly every time without the frustration of being stuck to the barrel. Installation and removal are straightforward, and the mount features a 3/4-inch wrench and socket interface for easy on-and-off work.

Built from 4140 chromium-molybdenum steel with a black nitride finish, the KeyMo Zero is tough enough for hard use while staying lightweight. It's compatible with any Dead Air suppressor equipped with a KeyMo or Keymicro adapter, giving you flexibility across your suppressor collection. If you're running multiple .45 ACP platforms or want to swap your can between rifles and pistols, this mount makes that workflow seamless.
