Prometheus EG Torque Hard Gear Set for Tokyo Marui Shock & Recoil New Ver.1/2

For recoil shock series AEG gearboxes, high torque gear sets are a must-have when modifying such weapons to take stronger springs. These gears are for the new shock recoil gearbox versions 1 and 2 (AK74, M4, 36K). This set comes with a sector gear, bevel gear and spur gear; this set does not come with bushings, a piston or a cylinder.
