Where can i refill my CO2 tank?
sure, gennerally there are 30lb co2 tanks and 50lb tanks that
you can fill from, you will also need a fill station and
instruction from a air smith on how to use it, so it is fairly
expensive to own, but what a lot of people do it buy a fill station
and then rent a co2 tank for the day from a welding shop or another
place that will do it (scuba shops sometimes, propane stations, you
just have to do a little searching) for a 50lb tank i think it was
around $30-$40 so have everyone pitch in a few bucks and you are
covered for the day
