Hi Jepho

I had to read this thread a couple of times to get my head round it and now I understand that you already have the charging gear, but not the correct adaptor for your new Feinwerkbau to connect direct to the cylinder, so you had two options - 1. Is the option you chose for a quick release adapter so you can use it with your existing kit, or 2. Which is the cheap spacer that would allow you to use the Feinwerkbau filling adaptor that came with the gun?

This is also true on the HW100 with the two brass fittings it comes with, but no spacer!

I've read a couple of you posts now, so welcome to the forum, you seem quite a switched on guy

Enjoy.

James
