CNC Split Gearbox V2 QSC (8 mm)

RetroArms CNC Split Gearbox V2 QSC
RetroArms CNC gearbox is designed for building and upgrading airsoft AEG guns using a V2 gearbox. Both halves are CNC-machined from a solid block of EN AW 7075 T651 aircraft-grade aluminium, rather than being made from a conventional aluminium casting. The construction has been extensively tested with an M160 spring without signs of wear or damage. The gearbox features a QSC (Quick Spring Change) system for quick spring replacement and includes a universal CNC spring guide. The two halves are secured with stainless steel screws. Bearings are not included and can be selected separately from the RetroArms range. The gearbox uses standard V2 gearbox internal parts. Precise CNC machining ensures proper alignment of both halves, including the coaxial bearing holes. The construction also includes several details designed to simplify assembly and ensure reliable operation. The precisely machined hole for the anti-reversal latch prevents it from falling out, while the trigger hole keeps the trigger in place even when using a stronger spring. Micro-grooves on the pins for the trigger and tappet plate springs help prevent the springs from popping out. This is a Split model, meaning a split gearbox divided into a lower section with the gears and trigger and an upper section with the air compression system and spring. This design simplifies servicing and tuning, allowing you to adjust the optimal nozzle length, AoE and air compression system separately after properly shimming the gears. Installation of the CNC gearbox requires advanced technical knowledge and precise alignment of the entire assembly in the gun body. It is therefore not a universal Plug a Play replacement.
