PROMETHEUS Hard Piston

It is the parts which actuate and die out extremely for Electric gun. Therefore, we considered various kinds of actuation condition, and select the fine material for antifriction, wear-resistance, shock-resistance, durability, and heat resisting. Main body is reinforced as much as possible and rechecked the metal gear tooth which burden extremely. As a result, we made an excellent piston which can be compatible with high-cycle, also with high rate springs.
