ForgetClassC Reviewed by ForgetClassC on . Co2 tank guage? I just started buying co2 and was wondering how to gauge how much co2 is actually in the bottle. I bought 2 bottles and one was lighter. Does that mean there is less gas? Is there a specific weight or psi I should look out for on full tank? Just dint want to be ripped off. Rating: 5
