Dead Air KeyMount Muzzle Brake .223/5.56 1/2x28 2.60" Black Steel

The Dead Air DA101 KeyMount Muzzle Brake is a steel, black-finished muzzle device purpose-built for .223 Remington / 5.56x45mm NATO AR-15 platforms. Threaded 1/2x28 to fit any standard AR-15 barrel, it works as a fully functional standalone muzzle brake when the host rifle is run unsuppressed.

Measuring 2.60" overall, the KeyMount also serves as the quick-detach anchor for Dead Air's KeyMo suppressor system. Once the brake is properly timed and installed, a compatible KeyMo-equipped suppressor can be attached and removed in seconds without tools, giving shooters a single muzzle interface that handles both suppressed and unsuppressed duty on a .223/5.56 AR-15.

The DA101's porting is designed to reduce felt recoil and keep the muzzle flat for faster, more accurate follow-up shots, whether you have a can on the end or are running it as a plain compensator. As part of Dead Air's KeyMo ecosystem, the DA101 is the recommended muzzle device for KeyMo suppressor owners and for anyone planning to add a KeyMo-equipped can to their AR-15.
