CO2 Cartridges

CO2 capsules, also known as CO2 cartridges, are disposable pressurized cartridges used in many CO2-powered airsoft guns and airguns. The cartridge is typically inserted into the magazine or a dedicated capsule housing where it is pierced, releasing carbon dioxide that powers the gun.

CO2 provides a consistent and powerful pressure source, which makes it a popular choice especially for CO2 pistols, revolvers and certain rifles. Compared to many propellant gases, CO2 often performs more consistently in cooler temperatures, making it a practical option for outdoor use.

Our selection includes several sizes of CO2 capsules and cartridges, including the most common 12 g CO2 capsules, as well as 8 g and 88 g CO2 cartridges for different applications. We offer both single capsules and larger multi-packs, which are often a more convenient and cost-effective option for frequent use.
