Krytac Kriss Vector Upgraded

Hi. I want to sell my krytac Vector because i dont use it anymore. It has an upgraded gearbox. Perun mosfet, new gears 13:1 ratio, new shimmings, steel teeth fps airsoft piston and piston head, new spring. New hop rubber (maple leaf). Speed trigger. Shoots 342 fps. Nimrod tactical 27K super high torque motor inside with the 13:1 gears is fast enough for anybody (really good rate of fire :D ). It has 4 mags, some external accesories and a tracer unit (180€). Also comes with an m4 stock adapter if you dont like the original vector style and with a battery extender cap (11.1V with 1300mah fits inside easily) and i changed the connector to deans already. I asking 600 for the whole pack. If you have any question dont hesitate to write me a message. I'm interested in change for HPA M4 or AK. Thanks for watching.
