ASG Ultrair CO2 Cartridges

These are standard 12g CO2 cartridges, which are the industry standard for the vast majority of CO2-powered airsoft pistols and rifles. However, always check your specific airsoft gun's manual to confirm it requires a 12g cartridge before purchasing.

It is strongly recommended that you remove the cartridge after use. Leaving a pierced cartridge in your airsoft gun for extended periods can damage the internal seals and O-rings, leading to gas leaks over time.

No, these are pure CO2 cartridges. While some specialized cartridges include a small amount of silicone oil to lubricate internal components, these are designed for clean, consistent propellant flow without additives.

Shot count varies significantly based on your specific airsoft model, the ambient temperature, and your rate of fire. Generally, you can expect between 40 to 80 shots per cartridge, but efficiency will drop in colder weather.

Store them in a cool, dry place away from direct sunlight or extreme heat sources. Because they are pressurized steel cylinders, avoiding high temperatures is essential to maintain their integrity and safety.
