Ah, I see. Largely similar to how one would go about building a Semi-Auto gun from a parts kit here, albeit without the "once a machine gun, always a machine gun" rule employed in the United States.
It's interesting that in the US there is a stigma that European gun ownership is practically non-existent, because the laws are particularly strict. However, as this example shows that is not always the case and sometimes the reverse is true.
Anyway, Good luck and happy shooting with your rifle. It looks like a fantastic machine.
