Giss system is such a great mechanism,
I did film some footage of a cutaway of the Giss system in action at 1:20 in:

I’d love to get my hands on a 220, sounds like quite an important rifle. Apparently 11,000 were made but they come up on egun every now and then.

Cheers,

Thank you Matt. Your video is great too .

If ever you get a Mod 220, it is unique and very well put together.
All you need to strip it down is a flat turn-screw to undo the screws and remove the modular trigger, followed by unscrewing the lightly preloaded end-cap and you're done. The high quality of the internal components has to be seen to be appreciated.
An unusual thing is that the trigger sear does not hold the piston in the cocked position against spring tension, which means that the trigger can be set up with just the right amount of sensitivity.
Unfortunately parts are scarce.
