CO2 Cartridges for Airsoft and Air Pistols

Many airsoft guns and air pistols are powered by 12g CO2 cartridges, which provide a higher muzzle velocity than traditional gases like green gas and also work well in colder temperatures.

What to Consider When Using CO2 Cartridges

Capacity: A 12g CO2 cartridge typically lasts for 30–80 shots, depending on the efficiency and muzzle velocity of the weapon.
Compatibility: Make sure your weapon or tool is designed for CO2 operation; you cannot use CO2 cartridges in green gas guns.
Temperature Impact: CO2 performs better than traditional gases in cold temperatures but can still lose pressure in extreme cold.
Leak Prevention and Maintenance: Apply a drop of silicone oil to the valve threads before use to extend the lifespan of seals and reduce the risk of leaks. Since CO2 dries out seals, you should also maintain your weapon with silicone spray after use.
