Urgent Tank Help!!

[ThUnDeR1080]

Guys, is it alright to fill a 12 0z tank (1800 PSI) with N2O??? (Nitrous Oxide)? I dont see why not, N2O doesnt go up to 1800 psi but i dont know if the tank can hold it, or the gun

and why cant i just put compressed air into my tank..on it is writtin "1800 PSI" and "12 oz co2"
so why cant i just fill the tank up to 1800 psi with air or n2o? please help quick

C02 fills will give you 800-900 psi, not 1800. Anyways, you can put compressed air into it, but it won't give you that many shots at 900 psi, and if you fill it to 1800 psi with air it will screw your internals because it doesn't have a reg on the tank, just a pin valve. Please tell me you aren't going to try using a paintgun with nitrous oxide...

Please tell us you mean N2 (Nitrogen).
