Dead Air DA106 KeyMo Muzzle Brake | .338 Cal | M18x1.5

The Dead Air KeyMo muzzle brake provides a mount point for KeyMo-equipped and Sandman-series suppressors while delivering a flatter-shooting feel and reduced concussion compared to many traditional muzzle brakes. It is made from 4140 HT alloy steel with a black nitride finish and uses M18x1.5 threads for direct fitment on compatible .338 caliber barrels. The brake also allows the suppressor to be removed without carbon-locking on the mount.

Typical applications include precision and long-range shooting where controlled recoil and fast suppressor attachment are priorities, and big-game hunting where secure suppressor mounting and repeatable point-of-impact are important.
