I just bought an ion off of eBay. I put in the air and tried shooting but it wouldn't shoot and I could hear air leaking. I took it apart and it seams that inside it, one of the two tubes that is like screwed into the barrel is broken. The tube isn't broken just the screw that holds it in, it is cut in half. I can't secure the tube to the barrel thing because it won't screw in due to the screw being broken. This Is Why air is not getting to the barrel to propel the paintball. I'm 16 and this is my first paintball gun so I have no idea what to do. Any advice is greatly appreciated.
