About a year ago I purchased a paintball fitting co2 regulator from Kegconnection.com. Awesome product and well worth the investment. But as time has gone on, I've realized that it is time to get a bigger tank! rather than replacing the fully functioning regulator, I want to just buy the co2 gas fitting from tank to regulator. I figure it is only 10 bucks instead of 50 bucks. I am running in the issue of finding said fitting. So my question is this: Has anyone done this and if so, how did you do it?
