Selling tokyo marui gearbox from an AK. No spring included. It's a standard 6mm version 3 gearbox, included is a standard eg 700 tokyo marui motor with the motor housing. The piston, piston head, gears, and nozzle are all upgraded and ready to handle 400 fps+ springs. It also has a brass guide rod. I believe the piston is deepfire. I'll take it apart tonight to verify every component, and photograph it. This gearbox is NOT shimmed.
This is a gearbox for someone experienced in working with gearboxes and would make a great addition to any AK based platform. Will also include a used prometheus barrel for a mere $50 extra (plus any extra shipping and handling, if need be).
Of course, feel free to purchase any components in person as I live right here in Ann Arbor.
