Individual sales also available below. Custom V3 Gearbox – GATE ASTER V3 – $125 Custom V3 gearbox originally built for a Mosquito 3D-printed airsoft project. Includes: GATE ASTER V3 ETU/MOSFET Ball-bearing bushings Shimmed gearset Polycarbonate piston with metal rack Upgraded piston head/O-ring Upgraded cylinder head Upgraded nozzle Custom ported cylinder Spring/spring guide Wiring and remaining internals pictured This gearbox was installed and live-fire tested in the Mosquito build and shot properly when last used.
