There is no such thing as a "CA" tank.
No, paintball co2 is much higher pressure.
It depends on the gun, but "both" is an acceptable answer.
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.
You probably could fill it, but not to pressures needed for paintball gun operation, CO2 tanks should not be filled with any gas or liquid besides CO2. edit: you could use Argon in a HPA tank but not a CO2 tank
There is no paintball gun that runs on only 200 psi.
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
Yes, the largest CO2 tank, the 24 oz can fit on the Brass eagle Raptor or any marker for with standard ASA threads. However not every marker can use Co2.
No, It is strictly prohibited in the manual. It will cause the gun to jam up.
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
Co2. Buying a Hpa tank for a cybrid is money that should be spent on a better gun.
