Does anyone know anything about a "maintenance" CO2 bottle for a CO2 airgun? I have a Walther PPK blowback CO2 airgun but did not know these things existed until a friend told me about them. Anyone know if you need to use these things regularly or where you can get them?

there actually is a maintainance bottle for C=2 guns, I've got a couple back in storage and I use them every five or so regular bottles. They are supposed to lubricate the valves and the gas counduits as the CO2 makes them brittle. You should be able to find them easily, they are marked Walther.
