It depends on the gun, but "both" is an acceptable answer.
It depends on the KGS system, and the FPS of it the gun.
No it can only use HPA because the CO2 will mess up the soleinoid and possibly damge your gun
No. Nerf guns always use springs to pressurize a small amount of air in a small plastic tube, where paintball guns have a highly compressed air or co2 tank in steel or carbon fiber tank.
No, It is strictly prohibited in the manual. It will cause the gun to jam up.
Yes. High pressure Air tanks (HPA) is compressed air, which is mostly Nitrogen. "Nitro" is not what HPA they are called, unless you are talking about Nitrous oxide, which is used in anesthetics and motor racing.
only if it is built to handle co2. weather or not a marker can use CO2 depends on how it is built not which firing modes it has.
If you meant "why do you need any gas tank for Paintball": the expanding c02 or hpa is what pushes the ball out of the barrel at high speeds and can be used in reseting the gun. If you meant "why you need a C02 tank specifically": you dont need a co2 tank to play paintball. their is compresed air tankes available. most electrical guns must run on air enless you want to be doing maintenance on the gun after every game and replace parts after 5 games. most non electrical guns also can be ran on air but is capable of runing on co2 but air would keep your gun in better condition. You need co2 or compressed air(nitrogen and compressed air are the same thing) so the paintball can fly out of the barrel and to re cock your gun automatically.
There is no such thing as a "CA" tank.
If your gun is meant to run on CO2, then it will function well. If it is not, then it will jam up when the liquid gets insides until the gun completely jams up.
No, only guns that are designed for propane should use it.
Yes. Paintball guns are definitely pneumatic. They run on compressed gas, Co2/Compressed air, and use the release of that gas to power the mechanics inside and propel the paintball forward toward a target.Information provided by Bullit Paintball teamcaptian: Nolan M.
no you will mess your gun up if you shoot it under water and the c02 is not cold enough
