CNC Gearbox V3 AK (8mm) - QSC

Retro ARMS reworked and upgraded CNC gearbox, codenamed "7075 series".

The V3 version of the gearbox is fully machined on a CNC machining center. Unlike other aluminum gearboxes, ours is made from a solid block of AW EN7075 T651 aluminum.
The original block weighs 1550g, and only 143g of material remains. This isn't a mold like the Chinese ones!
Our gearbox has been tested with an M160 spring, showing no signs of long-term wear or breakage. The gearbox surface is decoratively anodized.

The gearbox is equipped with a Quick Spring Change (QSC) system. It includes a CNC spring guide.

The kit includes CNC gearbox housing, CNC spring guide and a set of screws.
