Dead Air – KeyMo Muzzle Brake, Suppressor Mount, Nitride Steel

Dead Air’s KeyMo Muzzle Brake: Your First Step Toward Silence.

Whether you're running a suppressor or just want exceptional muzzle control, the Dead Air KeyMo Muzzle Brake delivers. Compatible with all Sandman Series and KeyMo-equipped suppressors, this brake gives you a secure, carbon-lock-free mount while reducing recoil and muzzle rise with minimal concussion.

Even without a suppressor, the KeyMo Brake offers one of the flattest shooting experiences on the market—thanks to its precision-engineered port design and durable black nitride finish.
