what king of regulator are you using.
I have a ninja 4500psi paintball tank, but at first I didn't know the regulator was set @ 700psi. so I bought a 3000 psi output one, this is the pressure I can fill my Airforce Condor. now I was wondering if they will agree to fill it at the paintball shop . the regulator is gold instead of black and you can read "not for paintball"
thanks
