AGM MP44 with PolarStar Fusion Engine

AGM MP44 with PolarStar Fusion Engine:

Another conversion work by Bingo Airsoftworks, with the AGM MP44 AEG being the base gun with which they installed the PolarStar Fusion Engine, making the rifle ready to take in HPA tanks and a good performing airsoft gun which will be a welcome thing for those who prefer using HPA as power source when playing airsoft.
