I have a RT Pro with a PMI PureEneryg HPA tank. 3000psi, 48ci. Everytime I try to put it on my Pro, the o-ring shreads, and the air leaks (or vise-versa). I can put the tank on my remote and it works great. So I am wondering if this is problemw with one of the pins being too long, either on the tank or the Pro. My buddy has the same problem, same tank and gun. What would be the fix for this?
