850 Air Magnum is drill and tap the 88 or 90 gram (bottle?) for a Foster fitting.

On the 850 the whole thing is still short enough that the front of the plastic stock still fits on it, I checked but I don't usually put it on. I wrapped the cyl in black tape to hide the shine.

I used the Walther brand cylinder because, when I checked it, they are about 1/4inch thick at the base.

I used the smallest drill bit that I could for that tap size and also used an undersized tap so it would be a tight fit.

I bulk fill from a 20oz bottle that I have from my paintball era and it works just fine.

I realize that not everyone can or will want to do this, or will like the idea at all, c'est la vie...
