Compact metal cartridges filled with liquefied CO2 power both replica pistols and large air rifles – CO2 cartridges determine the autonomy, reliability and overall shooting experience of your airgun. In this guide, you’ll find a detailed overview of 12g and 88/90g cartridges, maintenance capsules, usage tips, compatibility notes and frequently asked questions.
What are CO2 Cartridges?
CO2 cartridges are sealed metal containers filled with liquefied carbon dioxide under pressure. Once placed in the airgun’s chamber and pierced by the mechanism, they release controlled doses of gas that generate the pressure needed to propel the pellet or BB. This technology allows many CO2 air pistols to function semi-automatically – every trigger pull delivers a shot without manual cocking, offering a realistic and fun shooting experience.
Main Types of CO2 Cartridges
12g Cartridges
The most common size worldwide. Small, non-threaded and very easy to replace. Mostly used in replica pistols and some rifles. A 12g cartridge typically delivers 40–60 useful shots depending on gun model, temperature and shooting pace. Compact, portable and affordable.
88g / 90g Cartridges
Much larger cylinders with a threaded neck that screw directly into the gun. Designed for rifles that require extended autonomy and a steady gas flow. They usually provide 200–400+ shots per cartridge, making them ideal for long training sessions, continuous plinking or professional use.
Maintenance Cartridges
These are 12g cartridges pre-filled with a small amount of silicone oil in addition to CO2. They are not meant for everyday shooting but should be used periodically – one maintenance cartridge for every 10–15 regular ones. The silicone oil circulates through the valves and o-rings, lubricating and preserving them, extending the service life of your airgun.
Pros and Cons
- Pros: Easy handling, realistic semi-auto operation, quick change, portability, autonomy options (12g or 88/90g).
- Cons: Performance affected by ambient temperature, limited shot count in 12g, regular maintenance needed for seals.
Who Uses Them?
- Replica owners: Enthusiasts who want realistic handling with famous pistol copies (Glock, Beretta, 1911, etc.).
- Plinkers: Casual shooters who enjoy fun, fast shooting at cans or targets without complicated setups.
- Newcomers: Affordable, simple entry into the shooting hobby.
- Demanding shooters: Users who prefer 88/90g for longer, uninterrupted sessions.
Compatibility Tips
Always check your gun’s manual or manufacturer’s specs before purchase. Some airguns are designed exclusively for 12g, others require adapters for 88/90g. Make sure to know whether your gun needs threaded or non-threaded cartridges.
Safe Handling & Installation
- Ensure the gun is on safe before changing a cartridge.
- Open the chamber or compartment as per manufacturer’s instructions.
- Insert the cartridge and tighten until the seal is pierced correctly.
- Do not attempt to refill or modify cartridges.
- Never store cartridges in direct sunlight or extreme heat.
Storage & Transport
Keep cartridges in a cool, dry place away from direct sunlight. Temperature directly impacts internal pressure and performance – in cold weather, expect fewer shots per cartridge. For transport, use original packaging and avoid impacts that could damage the seal.
