From the manufacturer
Upgrade your rifle's performance with the Dead Air KeyMo Muzzle Brake 1/2-28 .30 CAL, a versatile muzzle device engineered for serious shooters who demand both recoil control and seamless suppressor compatibility. This precision-machined brake serves as a high-performance standalone muzzle device while providing a rock-solid mounting interface for Dead Air's KeyMo system, allowing quick attachment of compatible suppressors when you're ready to go quiet. Key Features Durable Construction: Built from 4140 heat-treated alloy steel with a black nitride finish for exceptional strength, corrosion resistance, and long-term reliability in demanding conditions. Effective Recoil Management: The multi-port design reduces felt recoil and muzzle rise, delivering a flatter shooting experience with minimal concussion compared to traditional brakes. KeyMo Quick-Attach Interface: Features a sealed taper design positioned forward of the locking channels for consistent lockup, repeatable zero, and easy suppressor removal without carbon lockup. Standard Threading: 1/2-28 threads with a .30 caliber bore, compatible with a wide range of .223/5.56, .300 BLK, and other .30 cal rifles. Installation Ready: Includes a shim kit and timing instructions; pre-drilled hole at the 6 o'clock position supports pin-and-weld applications.
