Airsoft Parts & Custom Gearboxes – GATE ASTER V3 / Kestrel V2 / Prometheus / BCA Cleaning out some leftover airsoft parts and two custom-built gearboxes from previous projects. Prices in CAD. Detailed photos of gearbox internals available. Custom V3 Gearbox – GATE ASTER V3 – $175 Custom-built V3 gearbox originally used in 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 and O-ring Upgraded cylinder head Upgraded nozzle Custom ported cylinder Spring and spring guide Wiring and remaining internals as pictured Estimated equivalent new parts value: $300+ This gearbox was installed and tested in the Mosquito build and shot perfectly. It is not being sold as a standard drop-in V3 gearbox. It was built/configured for the custom Mosquito project and is better suited to an airsoft tech or someone comfortable working on gearboxes. Gearbox is in somewhat rough cosmetic condition and the bushings were secured in place with adhesive. They can be removed if desired. Some internal brands/specifications are unknown, so I’m not going to guess at them. $175 CYMA V2 Gearbox – Eshooter Kestrel V2 ETU – $150 Clean custom V2 gearbox built on a CYMA shell. Includes: Eshooter Kestrel V2 programmable ETU/MOSFET CYMA V2 gearbox shell Polycarbonate piston with metal tooth rack Upgraded piston head and O-ring Upgraded cylinder head Upgraded nozzle Ported cylinder Black anodized skeletonized trigger Gearset Spring and spring guide Spring guide spacers Remaining internals as pictured Estimated equivalent new parts value: $250+ I no longer have a complete gun to live-fire this gearbox. I have bench tested it: trigger activates the drive system, piston cycles and the tappet plate moves correctly. V2 is in very good overall condition. Some internal brands/specifications are unknown. $150 Prometheus 6.03 mm EG Tight Bore Inner Barrel – 141 mm – $45 Genuine Prometheus stainless tight-bore barrel 6.03 mm bore 141 mm length Clean internally Good condition New/reference value: approx. $85 CAD $45 BlackBlitz / BCA 18TPA Neo Magnet Motor – $30 18TPA Neodymium magnets Used Good general-purpose AEG upgrade motor New/reference value: approx. $55 CAD $30 Feyachi Red Dot Sight + Mount – $25 Compact tube-style red dot Picatinny mount Rubber lens covers Used New/reference value: approx. $45–55 CAD $25 Metal AK Hop-Up Unit + Bucking/Nub – $15 Generic metal AK AEG hop-up chamber Includes standard soft bucking and nub Used New/reference value: approx. $20–30 CAD $15 Pinty Compact Red Laser Sight – $15 Compact rail-mounted red laser 20 mm Picatinny mount Adjustable Used New/reference value: approx. $20–25 CAD $15 Misc.
