S&T TAR-21 With PolarStar Fusion Engine

S&T TAR-21 With PolarStar Fusion Engine:

Another nice custom job by Bingo Airsoftworks with coverting an airsoft Tavor AEG into a mean BB-spitting one with the PolarStar Fusion Engine... "The S&T TAR-21 comes with a plastic gearbox, which actually helps with the Fusion Engine conversion since the plastic is much easier to cut or mill than aluminum. The TAR-21 has some unique internal mechanisms, using push/pull rods for both the fire select and the trigger.
