Built this a few weeks ago, recently bought a car so i need to recoup my funds. Gate titan RA gearbox Ceramic bearings 10:1s seigteke gears Sp120 spring SHS or lonex cylinder head (cant remember) SHS air nozzle SHS piston New ASG 22k torque motor Magpul pistol grip Built it for single shot, might need a stronger spring to run full auto without some sort of pre engagement. NO TRADES. Will ship same day if bought before 3pm. Thanks
