Ah yes, sorry I keep thinking they're like fire extinguisher and have female threads.

its hard to get a seal on the pb tank very little treads make sure the tank is empty if u mod it or else your hand will have no skin

Your method chokes flow greatly.
What I did was champ the tank in a vice and used a big pipe wrench to remove the valve.

I'd suggest buying a regular airsoft gun. This seems way outta your league, twizi.
