Experience shows that this won't be the case.
Otherwise you could also try preventing rotation with a groove and a pin.
Or make sure that it can rotate by having it concentric enough and a bit of space to make sure it can.

Valid points, I'll consider this mod for the next one which will inevitably follow
Where did you get that tank JSR, its looks like a Ninja paintball one... and i only know of one other company that makes it and thats (c)RAP4
It is a ninja tank, from ebay here
Found this info on the tank:
The regulator on the pump tank is adjustable between 450 and 850 PSI by adding or removing shims in the spring pack. It is very easy to adjust and is reliable.
This would be ideal at 450 psi, I prefer less stress on the components and more shots per fill, even if at the expense of some performance.
If I manage around 800 feet per second for BBs I'll be a very happy man. Anything more will mean wasted air and extra noise.
Not too expensive for what it is in my opinion. Just a question for the better versed in paintball paraphenalia, will the valve open regardless of what I screw it into, what does the head look like? Is it a standard thread?
