Prometheus Hard Piston

£32.00
Write a Review

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 Hard Pistons have been developed through extensive testing of different combinations of materials, processes and treatments for maximum durability.
