Dead Air DA160 KeyMo Muzzle Brake .578x28 45 Cal Black Nitride

The Dead Air DA160 KeyMo Muzzle Brake is a big-bore quick-detach muzzle device that doubles as the QD seat for any KeyMo-equipped suppressor in the Dead Air lineup. Built for hard-recoiling host rifles chambered in calibers up to .458, the DA160 delivers efficient muzzle braking on its own and locks the suppressor on with a simple twist when sound suppression is desired.

The brake is machined from 4140 heat-treated alloy steel and finished in corrosion-resistant Black Nitride, so it is built to take the abuse of magnum-class hunting and tactical use. Its .578"x28 thread pattern fits the larger-bore host barrels common to .45 caliber and .458 caliber platforms, and the muzzle-seating KeyMo interface installs without shims or rock-set timing. The efficient muzzle brake design reduces felt recoil and distributes gas evenly for fast follow-up shots.

Once the DA160 is timed and installed, the brake stays on the host indefinitely. The shooter simply walks the KeyMo suppressor on and off as the situation dictates, going from a quiet, suppressed host back to a brake-only rifle in seconds.
