I am looking for a bulk fill adapter for charging the small co2 cylinder from a fire extinguisher for one of the Tau/Drulov type pistols. The one I am currently using is a brass lash-up soldered together by me, and each time I need to do a re-charge, I am wincing and waiting for a very unwelcome BANG!

This will be in the wanted section too, but I thought I might get more relevant traffic in this section.
