There are plenty of reasons why gas airsoft guns are gaining in popularity across the United States, such as accuracy, functionality, cost of operation, and realism. One of the most important factors about the maintenance and operation of these guns is the propellant, some of the most common being 134A, green gas, and CO2.

Most gas guns have been designed to use just one kind of gas, but this is not the only factor by which one should determine the best gas to use. Other factors like the temperature can seriously affect the performance of the gun because of the way the gas reacts. For instance, a gas that works well at room temperature may be too powerful in high heat, which can cause significant damage to your airsoft gun.

Cold climates can also influence the type of propellant you require for your gas airsoft gun. If you live in a consistently cold area, the gas that the manufacturer suggests you use may not work because the pressure inside the gun has gone too low to support the firing action. A case of reduced pressure can also cause the valve to stay open following fire, resulting in the loss of all the gas in the gun.

Using a propellant in a temperature that is too hot or too cold can cause damage to your airsoft gun so be wary of the temperature. Also, avoid using a gas that is more powerful than the gas the manufacturer originally intended for that design.

134A is usually used in Japanese made gas guns, but there are some brands of other origins that use this gas as well. It can be used in temperatures anywhere above 40 degrees Fahrenheit, though a general rule of thumb is to upgrade to green gas when the gun begins to misfire.

Just about every other non-Japanese airsoft gun on the market is made for (or at least can use) green gas, the most popular airsoft gun propellant. Green gas is more powerful than 134A, so you need to be cautious in hotter weather to avoid causing damage to your gun.

There is no specific temperature at which one should use a less powerful propellant than green gas. Instead, the general rule is not to use green gas in temperatures exceeding 100 degrees Fahrenheit or to expose it to direct sunlight for extended periods of time. If you are shooting continuously in hot weather, the gas pressure doesn’t get too high because of the constant release; therefore you can probably get away with green gas in this case.

Another type of gas propellant is CO2, though the airsoft guns that are made to work with CO2 are generally frowned upon by airsoft enthusiasts because of their intricacies which make them difficult to operate and maintain. CO2 still has a small but loyal following since this gas has the widest temperature range over the other options.
