When I pump the gun the tank doesn't pressurize at all. My first thought was that the check valve's busted, but given that I didn't plug the pump I can't see how that could have happened. The next option is that I screwed something up when I cut off the stock barrel and ripped out the air restrictor. Since the tank valve is all the way at the back near the trigger I don't know if that's possible either. It's one of those goofy back-pressure valves, not a normal pin valve like in at AT2k.
I know this is really vague, but if anybody else has had a similar problem and could shed some light on it I'd really appreciate it. I can take more pictures if needed. Thanks.
