Dead Air Keymo Deadair Da320 Keymo Zero 1/2-28 .30 Cal

The Dead Air Keymo Zero is a quick-detach muzzle device built for shooters who want a lightweight, repeatable mounting system for their suppressors. Threaded in 1/2-28 and chambered for .30-caliber rifles, this minimalist mount pairs with Dead Air's modular suppressor ecosystem to give you fast on-and-off convenience without the frustration of carbon-locking. If you run Dead Air silencers with Keymo or Keymicro adapters, the Keymo Zero gives you a practical alternative to fixed installations.

What sets this mount apart is its intentional design: the shorter profile means less intrusion into your suppressor's blast chamber, which translates to better sound performance and reduced overall weight on the muzzle. That matters whether you're building a lightweight hunting rifle or a precision range gun. The 4140 chromium-molybdenum heat-treated steel construction with black nitride finish handles hard use and cleans up easily between shoots.

Installation is straightforward—the mount accommodates standard 3/4-inch wrench and socket tools for secure installation and removal. Dead Air engineered this mount to work seamlessly within their modular system, so if your suppressor collection grows, your muzzle devices stay compatible. For shooters who value simplicity, durability, and the flexibility of quick-detach mounting, the Keymo Zero delivers without unnecessary complexity.
