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.
A paintball gun needs CO2 (or HPA) to fire at all.
Yes, The Tippmann Response trigger runs on the guns excess CO2, and allows automatic fire. Otherwise, there are not current (there were old ones) that can go fully automatic without batteries.
A Co2 gun can go up to 300 fps. Sling shoots only get a paintball up to 240.
No, it is semi-automatic only.
It has a switch that you can choose between four settings. One is semi-automatic another is 3 round burst shot and the last one is fully-automatic.
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.
yeah
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).
