Green Gas Vs CO2 – Which Is Better For Airsoft Pistols

Green Gas Vs CO2 – Which Is Better For Airsoft Pistols? Among the many factors to consider when it comes to picking up new Airsoft Guns, such as which pistol feels better in your hand or which is more accurate, is which propellant should be used.

CO₂ or Green Gas? Both Green Gas and CO₂ operate in very similar, fundamental ways. These gases are frequently employed as propellants for pistols and, in some occasions, rifles, and are kept in the gun’s magazine. When you pull the trigger, some of the gas is pushed into the nozzle, blasting the BB with enough force to launch it out of the barrel and for the pistol to cycle.

Compressed gas is the most frequent way of shooting BBs out of the barrel in the realm of pistols. After all, we’re talking about airsoft guns here. When it comes to repeating and blowback pistols, shooters will encounter two basic propellants: CO₂ and green gas.

While both forms of propellant function quite similarly in the workings of the airsoft gun, there are a few variances in the gases themselves that need to be considered.

Green Gas 

Green Gas consists of a container containing a pressurised gas mixture of propane, silicone oil, and various fragrances. The silicone oil is intended to lubricate and clean green gas airsoft guns as they are shot. In addition to silicone oil, many green gas products contain other ingredients designed to mask the strong (and unpleasant) propane odour. However, it is this propane in Green Gas that is the key to the firing of the airsoft gun in the end.

In reality, regular propane can also be used to power green gas pistols. However, this is not suggested because the silicone oil in green gas plays a crucial role in keeping the gun functioning properly – mainly by keeping the different O-rings in the pistol well-lubricated.

Green gas is held under high pressure within the gun rather than in an external canister. Green Gas is actually kept liquid when stored. However, when you pull the trigger on a Green Gas gun, a small amount of gas is emitted and rapidly expands into a gaseous form. This generates the pressure required to launch a BB from the gun. While propane is a highly flammable material that is generally fired to provide energy by most propane-powered products, no ignition actually occurs here. Green Gas weapons are powered purely by the pressure released when green gas transforms from a liquid to a gas.

Green Gas Advantages: Affordable, Reliable, and Simple

There are numerous advantages to using both Green Gas and CO2. For Green Gas, this includes being easier on the barrel, more cost-effective, and frequently easier to maintain full magazines. Because Green Gas has a lower pressure than CO2, it will be less harsh on your gun. Furthermore, because it contains silicone oil, it will partially lubricate your pistol while you fire. However, just because there is silicone oil in the gas does not excuse you from cleaning your pistol correctly. You should continue to do so either way.

Green Gas is also less expensive. Green Gas costs upwards of £10 a can, and depending on your pistol, you can get more than 800 bullets out of each. Finally, because you can simply top off the magazine when using Green Gas, many people find it easier to ensure you have full capacity. As a result, Green Gas has several significant advantages, including weapon dependability, low cost, and ease of usage. However, CO₂ has several significant advantages that might fit some shooters better.

CO₂

The chemical shorthand for carbon dioxide is CO₂. CO₂ airsoft guns work in the same way that green gas airsoft guns do – when the trigger is pressed, a small amount of pressurised CO₂ is expelled from the gun’s CO₂ canister before rapidly expanding to create the pressure required to blast a BB out of the gun.

CO₂ fuels practically all BB pistols and several 6mm airsoft pistols. 12g CO₂ cartridges are widely available: almost any department shop and nearly all outdoor-centric retailers, such as your local airsoft dealer, will stock at least one brand of CO₂. This propellant has been used successfully in airguns for many years.

CO₂ Advantages: Harder Kick, Faster FPS

CO₂ has numerous advantages. While Green Gas is easier on the gun and less expensive, this does not mean that CO₂ is worthless. In cooler temperatures, CO₂ will kick harder, shoot faster, and work better. A CO₂-propelled handgun will kick harder than a green gas weapon due to its increased pressure, and so most CO₂ pistols have higher FPS than their Green Gas counterparts. Finally, due to the self-contained cartridge design, CO₂ will perform better at higher temperatures than Green Gas. CO₂ cartridges often cost less but only provide between 30 and 50 shots per cartridge.

Here’s a quick rundown of their advantages and disadvantages:

Advantages of CO₂

1. Better Cold Weather Performance.
2. Less Cool-Down.
3. More Consistent Power Curve Across Magazines.
4. Smaller, More Portable Bulbs.

Disadvantages Of CO₂

1. More expensive than green gas.
2. More corrosive to a gun’s rubber components.
3. Unable to top off the gun.

Advantages Of Green Gas

1. Ability to easily top-off a gun.
2. More affordable.
3. Widely available.
4. The ability to keep green gas in the gun between uses.

Disadvantages Of Green Gas

1. Larger and more difficult.
2. Lower muzzle speeds.
3. Poor cold weather performance results.
4. Faster cooling.
