Dead Air Armament Key Mount AR 15 Muzzle Brake – .223/5.56 NATO – 1/2×28



Optimize your AR-15 with the Dead Air Armament Key Mount AR 15 Muzzle Brake – .223/5.56 NATO – 1/2×28, a premium muzzle device designed for exceptional recoil management and muzzle rise control. Engineered to fit seamlessly with Dead Air's Sandman series of suppressors, this muzzle brake features compensating ports drilled into the top, effectively reducing recoil and muzzle climb.

The Key Mount Muzzle Brake shortens recoil length, preventing overlapping shot energy and ensuring consistent accuracy. With reduced recoil and muzzle climb, even full-auto fire remains precise, keeping all shots on target.

Experience the gateway to silence by quickly attaching your Sandman-L or Sandman-S suppressor for quiet and uncompromised operation. Alternatively, enjoy improved shooting performance with minimal concussion compared to traditional muzzle brakes.
