I just recently got a spyder VS2 off of action village. I decided to go with the package deal on the right for 75 dollars cause it looked like a lot better equipment than the other package. Of course I didn't check to see exactly what kind of air tank it was, and when it finally got here I saw it was a CO2 tank. Of course stupid me didn't know that the VS2 only takes air. I went and got the CO2 tank filled and tried to hook it up but of course I couldn't get any pressure. I'm assuming since It was CO2 and filled up that the pin could not pierce the tank, since the pressure was too high, letting no CO2 get into my gun. I did try to force it a little but to no avail. Now that I know that I need a O2 tank I was wondering since their was no pressure ever released is their a chance my gun could have been damaged at all?

Also, will any 20oz air tank do the job? or are their any differences I should know about which air tank to buy? or is their a recommended air tank that a lot of people with VS2 use?
