pressure in C02 tank

[sk8erkid530]

Can u put a pressure gauge on a C02 tank?........or is there another way to see how much C02 you have left?

you dont need it, theres no point, you can see when it becomes less heavy that it needs air.

co2 is cheap, so i do recommend switching to HPA

no there is no way to mount a guage on a co2 tank. it wouldnt help anyway because co2 puts out a constant pressure (~850 psi) until the tank is empty. the best way is to just keep track of how much you shoot and fiill accordingly. theres a chart on http://www.ottersccustoms.com/air.html that tells you how many hsots to expect form each size tank

it's not that hard to tell how much Co2 is left in your tank
even if you dont fill tans up at a field like i do.
