The Dead Air Pyro Blast Shield Insert is a practical solution for shooters who want to reduce the noise and pressure associated with a muzzle brake. Designed to redirect gases downrange, this insert is ideal for confined spaces like indoor ranges or shoot-houses. When paired with the KeyMo Adapter and KeyMo Flash Hider or Brake, the Pyro Blast Cap transforms your setup into a high-performance linear compensator and blast diverter. Please note, this insert is not compatible with KeyMicro or Xeno muzzle devices.
