I have a JG Bar with a PDI hop up version 2 (this is version 1 that includes the spring) but I need this spring to keep the arms on my hop up down which pushes down on the nub as the two bands included do not do enough justice. Can someone tell me how I can get this part solo or something compareable

Can't help with tapering spring like that, even more so in a small dimension like that. But i would advice to try to put a smaller o-ring so it can contracts more than the rubber band provided, or put more o-rings.

I would recommend getting a spring from the hardware store and trying to bend it into shape. Sounds like a disaster though so you should just get the action army hopup chamber!!

take apart a mechanical ball pen and you can cut that spring to fit your needs
