Driving the power source and recoil engine, the gears and piston take the heaviest load in the gearbox and this is magnified when upgrading the Marui Next Gen series. The life span of these parts can be half or even one quarter of conventional electric guns. The Prometheus EG Hard Gears have been developed through extensive testing of different combinations of materials, processes and treatments for maximum durability.
The Standard Torque gear set will handle almost any spring upgrades but for builds with higher power spring the Double Torque set will help the motor spin up faster for a better trigger response at the cost of a lower rate of fire.
Compatible with: Next Gen Ver 1 / Next Gen Ver 2 / Next Gen SCAR
