CNC Full Gearbox BLUE EDITION V2 (8mm), QSC

Uncompromising complete CNC gearbox V2 individually assembled and tested by RetroArms.

The CNC gearbox is assembled from the best parts on the market and designed for those who want a finely tuned gearbox for their M4.

CNC shell is manufactured from one solid block of aircraft aluminum (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-aluminum gearboxes.

The gears are fully CNC machined PandoRA 16:1 gears made of high quality hardened steel.

The gears are machined on RetroArms quality CNC machines from one piece of high quality hardened steel. Thanks to the material used and honest pre-production testing, RetroArms brings uncompromising quality and durability to the market. The gears were tested on an M210 spring in a CNC RetroArms gearbox with a RetroArms piston and other RA parts from thousands of shots.

The electronics is a high quality and proven Leviathan V2 processor unit with wireless setup via phone (free Android and iOS apps).

Likewise, the other parts have been selected with the highest quality and reliability in mind.

Gearbox is builded for 130 m/s (430 FPS / 1.7 J). Tested on DELTA ARMORY FREYA R15 with RetroArms hop-up chamber and WARHEAD 31k motor.
