$300 takes the complete lot. Cleaning out the remaining airsoft parts from previous builds. Two custom gearboxes plus upgrade parts, optics and miscellaneous hardware. Individual sales are also available at the prices below. Custom V3 Gearbox – GATE ASTER V3 – $160 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. Important: this is a custom build and is not being represented as a standard drop-in V3 gearbox. Best suited to someone comfortable working on AEG gearboxes. Cosmetic condition is rougher than the V2. Bushings were secured with adhesive and can be removed if required. $160 CYMA V2 Gearbox – Eshooter Kestrel V2 – $140 Custom V2 gearbox built around a CYMA shell.
