Can anyone help me to ID this shotgun barrel? It is a 12 guage semi-auto, vented rib barrel with the Heckler & Koch Inc-Arlington 22201 markings. On the left side of the barrel it says; CANONNERIE MANUFRANCE CAL 12,
and under that is; SAINT-ETIENNE Check the pics.......

It looks like the rotating bolt head of the Benelli.Have you taken apart the bolt ? I don't know if Benelli ever licensed anyone to make them.
