The only control you have is the rate of loss, so you just need to minimize this the best you can. All CO2 powered guns (whether they are BB guns or pellet guns, it doesn’t matter) will leak CO2 over time. So, is it possible to create a seal that will prevent the release of any carbon dioxide? Well, in a word, no.

You may notice the leaking more if or when you switch to a new type of canister that has a very slight difference in its shape. You won’t be able to see the deformation visibly, but it’ll be there. This doesn’t happen overnight but over a long-time and typically only if you’re using the same type of canisters over and over again. That’s 0.0000000005 of a meter! My point here is if they have an opportunity to escape, they will.Īnother reason it can happen is that the shape of the top of the CO2 canisters that you use can de-form the seal slightly. Now, carbon dioxide molecules are small so they don’t need much space to escape. This gas is doing everything it can to get the hell out and the only escape route for it is the tiny hole made in the top of it when you initially screw it in.

The CO2 canister that you have inserted into your pistol or rifle contains pressurized gas.
