A gearbox frame made of aluminum 7075 using CNC processing, dedicated for cooperation with replicas equipped with gearboxes V3. It is one of the most durable constructions available on the airsoft market.
The set contains, apart from the frame itself, a kit of 8 mm ball bearings, which allow for the installation of more powerful springs and a decreased rolling resistance, which increases the replica’s reliability.
This frame version features a Quick Spring Change System that allows to change it without having to open the gearbox.
