Green Gas Airsoft What Is It

Table of Contents [Hide]


If you are into airsoft, you may already have heard of green gas, but do you know what it actually is? When it comes to gas airsoft guns, the propellant used is green gas. Green gas is a combination of propane, silicone oil, and a lubricant formulated specifically for the airsoft sport. This special mix is ultimately what helps your powered airsoft gun shoot smoothly and accurately.

In this article, we will look at 8-12 relevant topics that will serve as an introduction to green gas airsoft and provide you with a deeper understanding of what it is and why it is important to the airsoft community.

Definition of Green Gas

The first key topic to understand is what is green gas? Green gas is a special mixture of propane, silicone oil, and frictional lubricant formulated for use in gas-powered airsoft guns. This mixture helps to power up the airsoft gun and gives it the smooth action and accurate shooting that players have grown to love. It also helps to protect the internals of the gun from extreme wear.

Benefits of Green Gas

The next important topic to discuss is the advantages of using green gas in airsoft guns. In comparison to other propellants, green gas offers several benefits. Firstly, it has increased power in comparison to Co2. Secondly, it is sealed in heavy duty containers which eliminates the loss of vapours. Lastly, it is less corrosive than other gases, reducing the amount of maintenance needed. This makes it an attractive option for airsofters who value performance over the cost of the gas.

Drawbacks of Green Gas

While green gas has its own advantages, there are some potential drawbacks to consider. One of the major disadvantages of green gas is that it requires more maintenance than Co2 gas. As the gas is cold, it may cause internal wear on the airsoft gun which can be costly in the long run. Additionally, due to the high power of green gas, it may cause over-hopping of heavy BBs.

Types of Green Gas

There are several different types of green gas available in the market. As many airsoft guns vary in their designs and internals, there are specific mixes of gases to accommodate this variety. Depending on the airsoft gun, some of the most popular green gas types include Bio-Green Gas, Pro-Tech PR-200 Standard Power, Pro-Tech PR-300 High Power, and more.

Filling a Airsoft Gun with Green Gas

The next key topic to consider is how to properly fill an airsoft gun with green gas. This process is fairly simple and requires only basic tools. Firstly, place the bottle of green gas in an upright position on the ground. Secondly, use an adapter and gas extension tube to connect the bottle to the airsoft gun. Lastly, press down on the top of the bottle to fill the gun with gas.

Using Silicone Oil with Green Gas

In some cases, you may need to use silicone oil with green gas. This is because airsoft guns are usually powered by pressurised green gas which in turn pressurises the lubricant inside the gun. As the lubricant is exposed to high pressure, you may need to add an extra drop of silicone oil to the reservoir in order to keep it functioning properly.

Storing Your Green Gas Bottle

Another topic to consider is how to store your green gas bottle. This is important as the gas must be kept in a secure and cool place in order to prevent leakage or avoid accidents. It is recommended to store your bottle out of direct sunlight and in an upright position. You should also ensure the bottle is stored in a well-ventilated area to prevent any build-up of gas.

Understanding Green Gas Pressure

Finally, understanding green gas pressure is an important topic for airsofters to learn. Generally, the pressure of the green gas in the reservoir should be between 900-1200 PSI. This is the optimal pressure which will allow the gas to be used without affecting the internals of the airsoft gun.


In conclusion, understanding green gas airsoft is an important part of understanding the airsoft sport. This article discussed 8-12 relevant topics that served as an introduction to green gas airsoft, providing a deeper understanding of what it is and why it is so important to the airsoft community. We discussed the definition of green gas, the benefits and drawbacks of it, the different types of green gas, how to properly fill an airsoft gun with it, the use of silicone oil with green gas, the correct way of storing your green gas bottle, and understanding green gas pressure. We hope you now have a better insight into this important part of airsoft and enjoy your games with greater ease.
