unscrew the tank, this will vent any co2 that is in the marker out the asa
yeah
A paintball gun needs CO2 (or HPA) to fire at all.
You cant, the CO2 that is in the marker is vented out when you take the tank off.
No, you should only run the G4 on HPA.
A Co2 gun can go up to 300 fps. Sling shoots only get a paintball up to 240.
you need Co2 to fire any paintball gun, it is what physically moves the ball out of the barrel.
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.
It depends on the gun, but "both" is an acceptable answer.
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.
CO2, stored in the tank is highly pressurized. The paintball being shot is caused by it being pushed out by the rapidly expanding gas. CO2 also cycles and reloads the next paintball.
The very basics are: a certified paintball mask, a paintball gun, paintballs, and a propellant source (co2, HPA).
It depends on the KGS system, and the FPS of it the gun.
