Fully upgraded. I don’t believe there is a stock part left. This gun was built by Airsoft Barracks in Florida. This gun was built to be an over reliable tank. I don’t have a parts list and I won’t take the gearbox apart. I’ll try and list out what I can see. Parts list: Gaurder 6.04 barrel Silver full cylinder New spring New piston, looks like shs or xhightec Stock old gen indestructible KWA gears New G&P devil jet 170 motor New 16 gauge wiring to the rear with deans Strike industries trigger guard Comes as shown, with what is shown. I’m asking $250 plus shipping. NO AIRSOFT RELATED TRADES, PROBABLY NO TRADES AT ALL. I also have batteries and mags to sell with the guns
