Dead Air DA161 KeyMo Muzzle Brake .45 Cal 5/8x24 Black Nitride

The Dead Air DA161 KeyMo Muzzle Brake is a quick-detach muzzle device purpose-built for .45 caliber rifles and rated for cartridges up to .458. Built around Dead Air's KeyMo mounting interface, the DA161 lets you convert to a fully suppressed host with a single twist when paired with any compatible KeyMo suppressor.

The DA161 is threaded 5/8"x24 and wears a durable Black Nitride finish. Its ported design is engineered to tame muzzle rise and evenly redirect propellant gas, cutting felt recoil on hard-kicking big-bore platforms without the harsh side blast common to more aggressive designs.

Weighing just 3.4 oz and measuring only 2.58" overall, the KeyMo brake adds minimal length and weight to the host rifle. The muzzle-seating shoulder indexes flat against the crown for repeatable, shot-to-shot lock-up and a consistent point of impact.

Whether you're running a heavy-recoil hunting rifle, a hard-kicking single shot, or any 5/8x24 threaded big-bore platform, the Dead Air DA161 KeyMo Muzzle Brake is your gateway to Dead Air's KeyMo suppressor family.
