I sold my benelli Nova pump 20 ga. with a green mountain slug bbl to a friend. I checked with he and he would sell it if your interested. I used it one season in Iowa, he lived in Northern NY at that time and was in a slug area. He was transferred before he ever shot it. It shot extremely good for me. It is scoped I am not sure if he would want to part with the glass, but the rings I am sure would stay.
FYI
