I have one of those soda club carbonating machines at home, there is an adaptor for the bottels on ebay and i could even fill them my self. They have a very high pressure and i think i could do alot of stuff with them(power my new rifle!). Any opinions or ideas appriciated, i feel a bit bad and so if i did not supply eanoth detail please tell me.

Care to go into some more detail in regards to your club soda machine? Are you talking about using the pressure from the carbonation tanks?

well yes, i want to either screw an adapter dictly to the tank and use it full on, or to attach a pipe to the end of the nozzel of the carbonater and to attach the other end to my chambers fill valve...

I by no means am trying to double post but i really need an answer to my little question...I am trying to build this gun as strong as possible and i have five main ways to power it, maybe some one could help me out!:

1. Soda clud tank with regulator to fill the chamber
2.CO2 cylinders gor bikes
3.N2O cylinders used for wipped cream
4.A tank with pressurized air
5.A hand pump

I need power, cheepness and safty, what of the above meathods should i choose? I am anxious to see all the responses i will get!
