If I add a Dlask 9" barrel to my GSG 16 but decide to use a working HK MP5 collapsible stock instead of a fixed stock the length could be made less than 660mm (26") and therefore restricted.
What would I have to do to get it registered as such and now that it would be restricted would there be a restriction on capacity?
