what is the difference between green gas and co2?

[DI Sessa]

I know they are both gas but I have no idea what each of them do that the other can't do.

Green Gas is propane (usually with some silicone lubricant pre-added and a different odorant).

Co2 is Co2 and also rarely also referred to as Black Gas.

Propane is cheaper (you can use those Coleman camping tanks) and is the defecto gas used in gas guns.

Co2 is usually in the form of those 12gr disposable cartridges and will cost more to operate: it does provide more power in a lot of guns (which can be a good or a bad thing, as sometimes it will push muzzle velocity over field limits) and will function in slightly colder weather.

I think that the two main (functionality-based) reasons that people will use one over the other in different situations are:

* CO2 doesn't lose as much pressure when it's cold out. So if you're playing outdoors in the winter, you'll have less pressure (sometimes not enough pressure to even cycle the gun) with green gas. CO2 doesn't have this problem. Similarly, if you fire a gas gun fast enough, the green gas "cools down" and again, will cause problems with not having enough pressure (the cool down effect).

* CO2 magazines only require that you replace the CO2 canister. This means that when you head out on the field, you can just toss a bunch of CO2 canisters in a pouch, or put them in a shotgun card, etc, and "re-gas" your mags on the field. Green gas would require you to carry around a propane tank, or something that's usually more bulky than little CO2 canisters.

Green gas is usually the cheaper, easier way to go. Green gas is just propane, really, so you can buy those little coleman propane tanks for $3, and get a LOT of mags out of it.
I also prefer to stick the green gas nozzle into my mag and press, rather than open the mag and screw in a new CO2 canister, but that's just laziness. =P

Not entirely true. Propane just exhibits the cool down effect more prominently then that of CO2.

You will see a drop in FPS with a CO2 mag in cold weather.

propane smells like shit

Would love that but then I'd have to buy a fill station...

[DI Sessa]

is one more powerful than the other?

you can tap gas mags and attach an HPA line to it .. people have done it to gas sniper rifles and pistols

I came here to say that.
