You could try APD (Arizona Paintball Depot), but they are often hit-or-miss. If you can make the drive to Tempe, check out Gearbox Airsoft, they're the best in the state. However, I know my way around just about every gearbox type, myself. I might be able to work on it for you. Send me a PM if you're interested. You could also check out Airsoft Arizona (AirsoftArizona - "The Airsoft Resource for Zonies!"
) if you want somebody to help you out with any questions you have.
