Prometheus Spring Guide Versions 2 & 8

The Prometheus spring guide for ver. 2 gearboxes is a necessary upgrade for those looking to upgrade their version 3 AEG. The spring guide features hardened steel ball bearings at it's base that allows the spring to rotate more freely inside the gearbox, this releases tension that may build up in the spring, reduces the risk of spring breakage, and allows the motor to run more efficiently.
