Understanding the Intricacies of Red Gas in Airsoft

When it comes to airsoft, understanding the right type of gas to use can be a game changer. One such type of gas, dubbed ‘Red Gas,’ has unique properties that provide benefits under certain conditions, but also bring some drawbacks.

What is Red Gas?

Red gas is primarily used for firing high-end gas-powered airsoft guns. Contrary to its name, it is not red in color. It is propane stored at very high pressures, leading to higher velocity when fired. Suitable for colder temperatures, it can increase FPS (Feet Per Second) by 40%. However, it is not advisable to use in warmer conditions as it becomes excessively powerful. Although it is highly pressurized and can fire at higher velocities, it also carries risks such as wear and tear on the gun and can be dangerous if not handled with caution.

What is Green Gas?

Green gas is another popular choice for airsoft enthusiasts. It is essentially pressurized propane gas mixed with lubricating silicone oil and is odorless. Green gas is non-toxic and flammable but is considered safe when handled correctly. It is known for being a more common and affordable option as compared to red gas.

Is Red Gas More Powerful Than Green?

Yes, red gas is more powerful than green gas. The higher compression and pressure make it perform better, especially in colder temperatures, although it may cause more wear and tear over time.

Differences Between Red Gas and Green Gas

Red gas and green gas have several key differences, which are summarized in the table below:

Factors to Consider When Choosing Gases for Airsoft

  • Pressure, FPS vs. Limits, and Wear and Tear: Higher pressure leads to higher FPS but may cause more wear and tear.
  • Restrictions, Game Limits, and Other Players: Consider the FPS limits of the field and the perception of other players.
  • Weather: Temperature can affect gas performance, requiring appropriate selection.
  • Your Airsoft Gun: Consider the construction of your gun and its ability to handle different pressures.
  • Price and Availability: Consider the long-term cost and availability of gas in your area.


1. What is the composition of red gas airsoft?

Red gas for airsoft is primarily composed of Propylene (C3H6) mixed with silicone oil. The gas is highly pressurized, with a pressure of about 13 kg or 185 PSI. It’s the same thing as Map Pro cans, which are generally cheaper and readily available. The gas is recommended for airsoft bolt action sniper rifles and gas blowback pistols in temperatures ranging from 7ºC to 28ºC (45ºF to 82ºF).

2. What is green gas?

Green gas, also known as biomethane or biogas, is a lower-carbon version of natural gas. It is mostly composed of methane released when food or other natural waste biodegrades through a process called anaerobic digestion. The carbon dioxide is removed and the remaining green gas is sent to the national grid. From there, it is supplied to homes and businesses.

3. Which gas is best for airsoft?

Green Gas, specifically the Nuprol 2.0, is widely considered to be the best for airsoft. It is a versatile, all-year-round gas suitable for most airsoft guns. However, the “best” gas can vary depending on factors such as weather conditions, your airsoft gun’s build, and your game style.

4. Can I use red gas in any airsoft gun?

Red gas, due to its high pressure, should not be used in every airsoft gun. It is particularly recommended for airsoft bolt action sniper rifles and gas blowback pistols. Using red gas in a gun with a plastic slide, such as a Tokyo Marui pistol, could cause damage. Always make sure your airsoft gun can handle the pressure before using red gas.


Red gas and green gas are two types of propellants used in airsoft guns, each with its own unique characteristics and applications. Red gas, due to its high pressure, is typically used in colder weather and provides a higher FPS (feet per second), but can cause more wear and tear on your airsoft gun. On the other hand, green gas is a more commonly used propellant, providing reliable performance and less wear on your gun. It’s essential to consider factors such as weather conditions, the construction of your gun, game style, and maintenance requirements when choosing between these gases.
