The Airsoft Masterpiece EDGE blowback housing is an aftermarket upgraded aluminum housing for the TM Hi-Capa or 1911 platform pistols. Not only is this blowback housing a nicely colored internal piece, but also allows the pistol to perform better by having a more durable upgrade part that is less likely to break, or wear out with use. This piece houses the nozzle and works best with an upgraded nozzle from Airsoft Masterpiece.
