Green Gas v CO2 – Which is better for Airsoft Guns?

Green Gas v CO2 – Which is better for Airsoft Guns?

We have been asked many times, which is better for Airsoft Guns, CO2 or Gas.

In this post, we will break down the differences between the two types of propellant for your Airsoft Gun.

Often used as a propellant for pistols, and sometimes for rifles, these gasses are stored in the magazine of the gun. When the trigger is pulled some of the gas is released into the nozzle causing the bb to shoot, and the gun to cycle.

Differences Between Green Gas and CO2

Whilst both Green Gas and CO2 operate very similarly, there are some notable differences between the two. 

Green Gas is essentially propane, with some silicone oil added in, and the smell removed. Most of the time Green Gas is purchased in prefilled Airsoft Green Gas cans. Green Gas is stored in bottles, generally pressurised to about 300 psi, and you can fill up magazines by charging them through the fill valve. Depending on your gun, you will get differing shots per fill up, as well as different shots per can.

CO2 on the other hand is just straight air. It is pressurised Carbon Dioxide, and contained in a small metal cylinder. There are several sizes of Co2 Cartridges available, the ones commonly used in airsoft guns are 12g Cartridges which are about the same size as your thumb. CO2 will have a pressure of about 12,000 psi. Just like green gas, the CO2 will go in the magazine. However, unlike green gas, the whole canister will go into the mag, you won’t fill up the magazine itself.  

Benefits of Green Gas – Reliable, Affordable, Easy

There are many benefits of using both Green Gas and CO2. 

Beginning with Green Gas, some of the benefits of using green gas are that it is easier on the gun, more cost efficient, and is often easier to keep magazines full. 

Because Green Gas has a relatively low pressure compared to CO2, it will not be so stressful on your gun. Also, because it has silicone oil in it, it will partially lubricate your gun as you are firing. However,  despite the oil in it, there is still regular cleaning maintenance required for Green Gas fired guns.

Green Gas is also more cost efficient. Green Gas costs anywhere from £8-£20 for a can, and depending on your gun, you could expect around 800 shots out of a can. Finally, because you can just top off the mag, many people find it easier to ensure you have a full mag when using Green Gas. So, Green Gas has some great advantages such as reliability of the weapon, being cost efficient, and ease of use. 

CO2 however is considered to have a much harder kick due to the considerably higher pressure it is stored at which causes BB’s to fly out faster and thus generating a higher FPS.

CO2 also tends to work better in colder temperatures due to it being contained in highly pressurised self-contained cartridges.

CO2 cartridges is a slightly dearer option with cartridges usually costing approximately a £1 each and usually you will get anywhere from 30-50 shots per cartridge.

The Ultimate Question – Which is a Better System?

Ultimately, if you’re reading this it’s probably because you want an answer however our view is you cannot go wrong with either and it will truly come down to personal preference.

Perhaps you can summarise as follows:

Green Gas = reliable, affordable and easy to use but requires regular maintenance and cleaning.

CO2 = harder kick, generates higher FPS, but slightly dearer option.
