Retro Arms CNC QSC Split Gearbox Shell V2 (8mm) #7066

CNC gearbox V2 designed for airsoft replicas AR15 (M4), M16 and other ones with V2 gearbox. This gearbox is manufactured from one solid block of aircraft aluminum (Dural) EN AW 7075 T651, which has higher strength (590MPa), than common construction steel (390MPa). Because of used material, our gearboxes have the best durability and resilience than common zinc-aluminum gearboxes. We are manufacturing these gearboxes on our precise CNC milling machines in our factory. Detail in bracket (8mm) means diameter for bushings/bearings. Package includes: CNC Split Gearbox V2 (8mm) – QSC in chosen color, set of screws and QSC spring guide. We made some useful improvements into our CNC gearboxes V2: Spring holders have grooves, so the springs for tapped plate and trigger switch will not jump off. Added groove for safety lever, so it will hold during installation. Added groove for trigger spring, for better fitting. AOE control hole. Sockets for bushings/bearings have smaller diameter about -0
