Yes, every few games, you will have to refill the tank, depending on the size. Without it, there is nothing to propel the paintball.
A paintball gun needs CO2 (or HPA) to fire at all.
you need Co2 to fire any paintball gun, it is what physically moves the ball out of the barrel.
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 CO2 tank is the propellant for the marker. It is very high pressure and is what physically shoots the paintballs out of the barrel, it is also what moves all of the internal parts, allowing the marker to fire and reload.
They need the small sealed CO2 cartridges, not the screw on tanks. but yes they need Co2 to function.
No, paintball co2 is much higher pressure.
Yes, it is what physically moves the ball out of the barrel.
On a paintball gun C02, or High pressure air is necessary. It is compressed air that, when the trigger is pulled and the marker fires, propels the paintball out of the barrel.
No, any tank will work.
A Co2 gun can go up to 300 fps. Sling shoots only get a paintball up to 240.
No there is no licence required to purchase/operate a paintball marker. In order to play you must be at least ten (at most places) and 18 to purchase a marker, balls, or CO2.
Yes. unless you use HPA.
