The Dead Air KeyMo Muzzle Brake (brand part no. DA106) is a .338 caliber brake cut to an M18x1.5 thread pattern for Accuracy International rifles, built as the gateway to Dead Air’s KeyMo quick-mount system. When it’s time to suppress, the KeyMo brake lets a shooter quickly attach a Sandman Series or other KeyMo-equipped suppressor. Run without a can, it still delivers a flatter-shooting rifle with less felt concussion than a traditional muzzle brake. When it’s time to remove the suppressor, the KeyMo design comes off cleanly without carbon-locking onto the mount, a common headache with other quick-detach systems.
