No.
Where the air tank or co2 tank normally attaches
The sizes 9 oz and all the way up to 20 oz can be used for paintball gun. Some of the paintball guns are supposed to be used by the larger tanks. So the size of tank depends on your paintball gun.
There is no paintball gun that runs on only 200 psi.
No paintball gun will work without a CO2 tank or other propellant tank. without Co2 there is nothing to push the ball out of the barrel.
A paintball gun, unlike airsoft or real firearms will have a hopper on top, and will have a co2 tank sticking out of the back.
There is no such thing as a "CA" tank.
No, any tank will work.
You shouldn't be playing paintball if you can't figure this out on your own. Alright?
Any gun with a High Pressure System (which is basically all of them) can use this tank.
You need an adapter (shown in link) then fill like a normal fill station.
