Part 1 of Wolf Airsoft Gaming's PolarStar Airsoft MG42 build, giving us an overview on how they will go about with their custom HPA airsoft project... "The start of an absolute beast, the polarstar conversion of the Matrix/S&T/A&K/AGM MG42 airsoft replica. One of my long time planned projects, and as the opportunity for savings presented itself I took it. This series is planned to explain the conversion to HPA, upgrades and improvements, and overall external reinforcement."
