Retro Arms Airsoft VFC V2 8mm AEG Gearbox Shell

CNC Gearbox V2 Umarex / VFC AEG (8mm) – QSC

CNC V2 gearbox shell designed for VFC AEG airsoft replicas with V2 gearbox. This gearbox is manufactured from one solid block of aircraft aluminium (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-aluminium gearboxes. We are manufacturing these gearboxes on our precise CNC milling machines in our factory.

Package includes a CNC V2 VFC Gearbox Shell, QSC Spring Guide, set of screws.

This CNC gearbox can be installed only in airsoft replicas made by Umarex. That means even the inner parts. Do not use too much force during installation. Use only 1Nm tightening torque on screws, otherwise the screws will overturn in heads. There is no need of tightening screws with too much force, if you want to be sure that screws will not loosen, use thread locker.

Retro Arms gearboxes have a quick spring change system QSC, where you can remove the spring guide with hex key and change the spring without need of opening the gearbox.

Please be aware due to the QSC system you need to make sure the stock screw is installed before operating the gearbox as this centres the spring guide. Failure to do so could damage your internal parts.

You can use in our CNC gearbox any spring of your choice but be aware that stronger springs will result in lower durability.

!! do not use MAXX cylinder head !!

Installation of the inner parts and gearbox requires professional knowledge, experience, and skills. There are a lot of airsoft manufacturers on the market and every one of them create their own sizes, there are no standards like engineering ISO in airsoft. This is the main problem with a lot of inner and outer parts from different manufacturers which can be same product, but with different dimensions.
