Perfect addition for my mpx - Dead Air Armament KeyMicro Flash Hider

The only concern I had when purchasing my Mpx was the reviews I had seen saying that it was difficult to suppress, and that the thread pitch on the barrel made it difficult to find a muzzle device that could be used with a suppressor without spacers or throwing the bore alignment off. This muzzle break took all the worry out, as it threaded right on to my barrel. Now I can use my suppressor with no worries.
