CNC Split Gearbox V2 with internal Hop Up Chamber 8mm - QSC Retroarms 6576 black anodized color

CNC split 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.
