CO2 airguns

I decided to write this post so I can collect some general information about CO2 airguns in one place, rather than spreading it across several reviews.

The advantages of a CO2 mechanism are that it takes little space, it operates with few moving parts, and provides enough power for several dozen shots. The main drawback is that once you load a CO2 powerlet, you need to expend it, because storing the pistol with it will damage the seal; also, CO2 airguns are noisier than spring piston or pneumatic airguns.

The small size of the CO2 mechanism makes it the best solution for powering firearm pistol replicas, as the 12g powerlet can easily fit inside the grip of a pistol.

When it comes to maintenance, the most important thing is to oil the tip of the powerlet with a special oil like the Crosman Pellgunoil - this will protect the seal from the cold CO2. Other moving parts need to be oiled sparingly, as needed. This makes CO2 airguns very easy to maintain and very robust as well.
