Depends on what your gametype or preference is. If you like the look of a co2 revolver for target practice then buy it. If your using a automatic pistol for cqb or a sidearm then get that.
Usually, the only non electric rifle this is also automatic will be CO2 powered.
this depends on a few things: if you want a gas airsoft revolver you can get a crossman or an HFC revolver. If you want a spring revolver the only one is the UHC revolver. the most realistic of the three is the UHC because it only fires six shots before you need to reload (the others fire 10 shots) the UHC is also the cheapest. But the more practical revolvers are the gas ones because you get more shots without having to reload (which is a use full feature when playing in an airsoft war). So take your pick. But if you want the best of the best revolvers in airsoft you should get a WG 700 series revolver or a Dan Wesson revolver. They are co2 revolvers that shoot extremely hard. They are somewhere in the 100-125$ range
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.
no
Depends on what type of revolver you're looking for. You can buy a spring revolver for £24.99. On the other hand, if you are looking for something a bit more substantial and for serious use you can always buy a gas or co2 version one for £55 or £60 (see related links). It may not be in stock currently however.
yes
Most all teams allows virtually all types of guns. The question is what fields are the CO2 guns allowed.
CO2 cartridges are used for tasks such as refilling flat tires and to carbonate soft drinks such as Soda. CO2 Cartridges are also used to power certain Airsoft and paintball guns.
Airsoft CO2 cartridges typically last for about 50-100 shots before needing to be replaced.
No. co2 airsoft pistols in general are plauged with leakage issues, especially a cheap crosman. Besides that, airsoft pistols are not a good investment unless you already have a good primairy rifle.
No it won't fire, Co2 is the power source that power the gun.
No. even though some spring guns have great range, co2 allows you to fire more then once before reloading.
