if that's the case and you got the nut off already, just contact the benelli distributor, which I believe is called stoeger canada and buy the tube.
also I meant this specific model which already comes with the longer tube for the wood furniture. it seems to be out of stock everywhere at this time, but it used to be available all the time since everybody wanted the telescoping stock one... it should come back in stock around July-August.
