Great tool - Dead Air Armament Pyro 2.0 Enhanced Muzzle Brake

Absolutely a must have for all suppressor owners and those who are on the fence or waiting for their form to be approved. Comes with the DA Keymo Adapter ($200), which is a necessary purchase. Overall performance is nothing spectacular but very adequate and does what it says it will do. Plus it wlll get you accustomed to the additional weight. Definitely recommend.
