Oxygen for GBB

Thank you Bean. I was avoiding posting that prior to getting to a PC to pull up info on liquid propane vs. liquid oxygen but here I go without. (still on my iPhone so excuse me if I ramble and possibly make mistakes)

When GBB mags are filled, you invert the propane tank to transfer it as a liquid. If you think you are getting mostly gas, try filling your mag with the tank upright and not the power and number of shots taken.

Now if you use liquid oxygen, it's going to be quite cold. It's boiling point is like -180C. As it vaporizes during a shot, it will likely freeze your pistols internals and destroy itself mid cycle if it can get that far. With compressed oxygen, if you could get it into your mag, it is possible that it will react with any lubricant or rubber and burn. Add the fact you have an abundant source of oxygen, it will go boom!

The amount of psi required to store compressed O2 is ridiculously high. The volume in your mag to store O2 as a gas would be so little that it wouldn't be worth it. The discussion of using CO2 is also constantly brought up and it just can't be done. You will blow a seal or have a nice explosion.

Liquid propane simply requires lower psi to maintain it in liquid form. While in liquid form it takes up less space and ultimately will provide you with more volume as it vaporizes.

I will edit this if required.
