Dead Air KeyMo Zero 5/8x24 Muzzle Mount .45 Cal - Black Nitride

The Dead Air KeyMo Zero is a quick-detach muzzle mount purpose-built for .45 caliber host firearms. Precision-machined from 4140HT alloy steel and finished in Black Nitride, the DA321 offers a lightweight, minimalist mounting point engineered for faster, more repeatable suppressor attachment.

Threaded in 5/8x24 to fit standard .45 caliber barrels, the KeyMo Zero installs as a permanent muzzle device on the host firearm. Once timed and torqued in place, it accepts any Dead Air KeyMo or KeyMicro adapter-equipped suppressor by hand without tools and locks up tight with a reliable, repeatable interface.

Fully compatible with all Dead Air KeyMo and KeyMicro suppressor systems, the KeyMo Zero delivers recoil reduction and muzzle control while giving .45 caliber firearm builders a clean, low-profile mounting solution.
