Bingo Airsoftworks went to work on something big for their latest PolarStar Fusion Engine Conversion project and they chose the Viva Arms M1919 Browning... "The Browning M1919 is classic machine gun widely used throughout the early to mid 20th century, but it’s not so common as an airsoft gun. Although there are several airsoft models available, you don’t typically see these on the field, generally due to their size and weight. The Viva Arms M1919 is designed as an airsoft gun utilizing a V7 gearbox. McCenzie Mento sent his Viva Arms M1919 out to be converted to use a PolarStar Fusion Engine as the V7 gearbox had broken apart. Machine guns are particularly well suited for HPA conversions like the Fusion Engine since they can handle a tremendous amount of rounds with little maintenance and no worries about the gearbox or piston breaking down."
