Crosman 111 bulk filling CO2

[Benelli B76]

Baz, do you invert the extinguisher so you get liquid CO2 not just gas in the pistol, as the ones I have do not have siphon tubes. ?
I experimented with CO2 filling a while ago as I wanted to adapt an extinguisher to fill my CO2 Webley Senior. I bought a CO2 regulator and valve from an aquarium supplies company, and, with Laurie's help, have now got both Sodastream and Extinguisher filling adaptors.
I knew I had some old style full Sodastream bottles, but couldn't find them so got hold of a discarded new style Sodastream machine, and removed the valve assembly and lever which is perfect for filling pistols, as the inverted bottle just needs to be slightly pressed against a hard surface for the valve to operate.
I have since found the old style bottles, so can still use the adaptor Laurie made for me to do a similar job, but the bottle has to be screwed into the adaptor to release the CO2.

You do not have to invert the fire extinguisher it has a tube that runs down into the liquid CO2 and up to the valve , you are dispensing liquid that's why they need a diffuser cone fitted.(see Google pics). I don't see the need to bother with all this complicated equipment that people use. I filled my mates FWB model 2 last year and it is still shooting, just coming up to a refill. The only time I use something different is when I fill my Drulov Eagle and Condor as they have their own design connection. I fill their bottle from the fire extinguisher and then transfer from the bottle.
