I have an upgraded Cyma pp19 bizon with 2mags, one hi cap and one midcap, and an 11.1v lipo stick battery, it’s upgraded with SHS 16:1 gears, a new wiring harness, shimming, maple leaf bucking, new spring, POM piston head, full metal rack piston and the gearbox has been cleaned and re-greased, this gun is full metal, the only things that are plastic are the magazine and the pistol grip, I’m looking to trade this for something else, arp9s and stock TM hi capas will take priority but I will look at all trades, local to SoCal ( Tac City, Extreme Tronics, Evike, Airsoft Gateway, Project N1 are places I can meet at), if you have any questions or offers feel free to hit me up, thanks for your time guys
