Yes, Co2 packs more of a punch than compressed air. They use Co2 for paint ball guns, and regular paint guns. It is also used for some BB or Air Soft guns.
Most all teams allows virtually all types of guns. The question is what fields are the CO2 guns allowed.
the gas powered air soft guns use CO2 or green gas
no
Air guns for you don't have to keep re-filling CO2 cartridges or buying new ones.
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.
The CO2 Guns are usually used for Paintball games or for Party effects. One can buy them at eBay, Air Gun Depot, Air Gun Buyer, Palco Sports, Pyramid Air and many more.
if u mean the tank that you put your shoulder against and what powers it. no u can get co2 or compressed air (compressed air is better for your gun)
No. Most airsoft guns that run off of CO2 use unthreaded, disposable 12 gram cartridges.
No you do not need to put air in an airsoft gun. These guns are either spring powered where you must cock the gun before you shoot it, electric powered which are automatic and require batteries, or CO2 powered which requires a CO2 cartridge. This CO2 is not expensive and a pack of 40 CO2 cartridges costs only 20-25 dollars. the guns that require CO2 are not as common as the other forms of airsoft guns, although they are more powerful. In general, if you buy an airsoft gun, you do not need to put any air into it.
it depends on their velocity. all three of them can have guns that hurt.
some of them are but most aren't, what kind of gun are you looking at?
