    Walter air pistol CPM mod

    A mod if you cannot get new CO2 cylinders.CPM-1 CO2 adapter.pdf

    Please note amendments for step 5.

    Your steel adapter should now have an external thread at one end and an internal thread at the other end with a hole drilled through the middle. The black holder body has its own adapter with the yellow O ring on it and that screws into the steel adapter you have just manufactured. See figure 5 (not 6).

    FWIW and as its rarely mentioned, most such Co2 cartridges keeps around 60bar worth. No matter if a 12 or an 88.
    Thought it might be wise to toss into the total equation.
