Best Airsoft Gas
Gas airsoft guns run on special propellants which are mixed with silicone oil. It makes shooting airsoft guns realistic compare to spring guns. The most common type of propellants is green gas, Co2, and 134A which are all gases. In the rest of this article, we will go into details about each of the gasses and give our expert opinion on which brands of gas are the best.
Types of Airsoft Gas
Green gas, CO2, and 134A are the most common propellant for airsoft guns. Out of the three, green gas is famous for its reliability and ease of use. Every airsoft gun depends on the design and manufacturer’s intent, and the temperature of the environment used. Using green gas on a steel airsoft pistol won't be able to cycle. CO2 on a plastic pistol will do serious damage to the slide and internals as it's not designed to withstand such pressure.
Always follow the manufacturer’s recommendations about which gas is best for your airsoft gun to deliver the best performance. Consider the weather conditions and temperature where you’re playing to find the next best answer.
- 134A: Popular choice for Japanese airsoft guns as they work better in weather conditions not too cold. With temperatures below 40 degrees, there is a difference in performance. Pressure from this gas is not intense enough to damage your airsoft gun. It's the safest gas making it a good choice for plastic airsoft guns. We do not recommend using this on metal guns as it may not cycle properly. It's the most expensive propellant of the three.
- Green gas: Propane is known as Green Gas, except that Green Gas has silicone oil mixed in to help lubricate moving parts and o-ring seals. The most common gas used and works better in weather conditions not too hot. As well as being a budget-friendly propellant, it's softer on your airsoft gun. What's great about this gas is it can be used on plastic and light metal airsoft guns. It can run steel airsoft guns but depends on the build and design. Some steel airsoft guns may not cycle.
- CO2: Best for performance as it provides the highest pressure of the three. Co2 can adapt to a colder environment but deteriorates your airsoft gun at a higher rate. That's why an airsoft gun designed to use CO2 will really only work with CO2. The higher pressure makes it easier to cycle steel airsoft guns. This does not work with plastic airsoft guns as the pressure will break them.

TOKYO MARUI HFC134A GAS
| Specifications | |
|---|---|
| Color | Blue |
| Brand | Tokyo Marui |
| Model | FITS MANY MODELS |
| Platform | GAS |
| Replica Type | FITS ALL TYPES |
| Net Weight (kg) | 0.51 |
| Length (mm) | 200.0 |
| Content Included | Tokyo Marui HFC 134a Gas (400g) |
| Material | Gas |
Ideal for shooting on lower power levels, HFC134A gas is clean and provides enough stable gas pressure to cycle plastic airsoft gas guns without damaging them. These types of lower gas pressures are best for Japanese spec gas airsoft guns that are legally prohibited from having metal components and firing at power levels beyond 0.98 Joules. The only downside to this nominally safe, clean and consistent gas is that it can be very temperature dependent and performance can vary significantly if it is too hot or cold.
Pros
- Least powerful of all airsoft gases
- Safe for use with plastic slide airsoft guns
- Clean And Integrated
- No Influences On An Ozone Layer
Cons
- Not suitable for metal airsoft guns
- Unstable in cold or hot environments

- Higher pressure stronger than Green Gas but weaker than Black Gas or CO2
- Consistent pressure
- Afforable
Cons
- Not suitable for plastic airsoft guns
- Muzzle velocity might be too high for most sites unless in winter
