Trade or Sell Licensed Taurus PT99

Looking to trade a fully auto CO2 GBB pistol, the selector switch on it only shoots safe and auto, but im sure this can be fixed, it has two 38 round magazines, shoots about 1 and a half mags to a canester of gas, 385 fps, one of the clips, the hex screw on the bottom is stripped, but this gun will fit a M9 clip... Looking to trade it for a GBB pistol or sell it for 120... its a basically new gun, the only thing that isnt metal is the grip, and its ABS. Willing to negotiate the price...
