The RetroArms CNC Gearbox V2 8mm for VFC QSC is a precision-engineered upgrade designed specifically for VFC-spec Airsoft AEGs using Version 2 gearboxes. CNC-machined from 7075-T6 aircraft-grade aluminum, this gearbox shell offers extreme durability and rigidity, making it ideal for high-performance, high-speed, or high-torque builds.
Equipped with 8mm bushing or bearing slots and a Quick Spring Change (QSC) system, this gearbox shell enables faster tuning and easier spring swaps without full disassembly. It is designed to fit VFC body specs more precisely than standard V2 shells, ensuring better fitment and alignment in compatible builds.
