This gearbox is manufactured from a solid block of Dural EN AW 7075 T651 aluminum, which has higher strength (590MPa) than common construction steel (390MPa). Retro Arms gearboxes have better durability and resilience than common zinc-aluminum gearboxes as found in most Airsoft guns.
This gearbox also features a quick change spring system QSC, which allows you to change the spring without opening the gearbox.
