Here's the advantage and disadvantage.
Spring airguns (Not airsoft) usually have more power than C02. Spring airguns and rifles can reach speeds up to 1650 FPS (Feet per second0 but they are single shot guns and rifles so you have to reload between shots.
C02 guns and rifles attain a speed up to 650 FPS but will give you multiple shots between loads. You can usually get about 60 to 80 shots from a 12 gram C02 cylinder. However you should never leave a C02 charged cylinder in an air gun because the constant pressure may eventually damage the seal. Or someone else may puck up the gun later and fire it not knowing it's charged and possibly loaded.
Never leave a spring air gun cocked it's will eventually damage the spring.
An air-soft gun that is powered by CO2 or green or red gas instead of a spring or a battery.
You can buy any gun in green gas, CO2, or electric. You just have to look for them....
Well no a Co2 cun justs uses compresed Co2 intead of a spring or a batery Co2 if fairly cheap and are easy to use
No. even though some spring guns have great range, co2 allows you to fire more then once before reloading.
Neither
All pellet guns use compressed air or gas. 1. Spring piston: Cocking the barrel of the rifle compresses the spring and piston inside the rifle or gun that is located in an air cylinder. When you pull the trigger it releases the spring and as the spring shoots forward, it pushes compressed air ahead if it that forces the pellet out the barrel. 2. Co2: A Co2 bottle it inserted into the gun or rifle, and it is full of compressed Co2. When you pull the trigger a burst of Co2 gas is released and the gas pushes the pellet out the barrel. This same idea is used for the larger PCP rifles only they use a much higher pressure bottle. 3. Pump: When you pump the forearm of the rifle it stores air in an air chamber. When you pull the trigger all the air is released behind the pellet forcing it out the barrel. BB guns work the same way.
No. The base of the guns are different and it is impossible to change it into a quality CO2.
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 the gun, but "both" is an acceptable answer.
Co2 comes out of a bb gun because of the compressed co2 cartridges that are used to propel the bb itself. Additionally, the bb gun that does not use co2 cartridges just doesnt shoot out co2, but air in general.
No compressed air would be better for accuracy as well as your gun. Its like co2 but at a higher pressure with cleaner air and no liquid that can damage your paintball marker.
If it is a gas gun, no. However, some are spring guns, and some are electric.
