Adapter for HPA guns to 9V batteries with JTS connector

P6 9V reduction to JTS adapter for FCU HPA systems Now you don't have to worry about whether you have a small Li-Po battery or Li-On battery charged for your HPA. With this reduction, all you need is a commonly available 9V battery. One battery will last you several events. You don't have to worry about a charger. You can buy batteries at any electronics store, hobby store, or gas station before an event. :)  The P6 9V battery fits comfortably into the M4's grip, for example. If you have the FCU connected to the gun's tube, you need to have the grip slightly extended.
