All paintball tanks are the same threads as far as I know.
Not to bust your balls but just in case anyone else is reading this and wants to do the same thing, you can buy an adapter to adapt a paintball tank to a standard regulator. A standard reg is like $40 and the adapter is like $15 I think. So $55 instead of $85 for the fancy reg.
