No.
Where the air tank or co2 tank normally attaches
A paintball gun is several magnitudes stronger then a Nerf gun. A paintball travels at around 200 mph, where a Nerf gun is around 10.
yes
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.
size is all personal preference, you can get something as small as a 9oz or up to a 24oz co2 tank, the larger the tank is the more shots you will get off of it but the heavier and larger it will be
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.
