Dead Air Armament flash hiders excel at keeping flash to a minimum, but sometimes you just want a flatter shooting rifle and don't care about the visual signature. That's where the Pyro 2.0 Enhanced Muzzle Brake comes in. Install it over your flash hider and just like that, your flash hider is a fully functional brake. Extremely effective, installs in seconds, and Keymo compatible. The all-new Pyro 2.0 muzzle brake utilizes their existing KeyMo adapter and the all-new Pyro vented shroud. Each part is available for purchase separately for those that already have a KeyMo flash hider. *Ships with a .30 cal front cap and is interchangeable with Sandman / R-Series front Mfg: Dead Air Armament
