Its more like $3-5 to fill a 20oz CO2tank
Really for me at a paintball store it costs a dollar.
Well you're lucky then

I work at a paintball field and I still pay $2.... Well actually I could fill it myself for free and they wouldn't care, but it's not like $2 is much
I normally use a $200 HPA system though... I have a 68ci 4500 psi tank with a max-flo regulator.... I can regulate 4500 psi from ~300 to .05 with my secondary regulator and air fills are practically free... At the field it's $5 for all-day [compressed] air...(They don't charge you to breathe

)... and at home I just fill a large scuba tank at the fire station, so it just cost gas money.

:tongue3:
Actually there's not much liquid CO2 in the tank if it is filled correctly. Liquid CO2 damages most guns (even some non-electropneumatic guns), so we are taught to keep it to a minimum in the tanks...
Some CO2 tanks are installed with anti-siphon lines, and some guns are fitted with "X-Chambers" (expansion chambers) so the liquid CO2 doesn't reach the internals of the gun, so there is
some in the tank... It varies per fill normally...
