I honestly have no clue but that is one odd looking shotgun..cant make up my mind if I like it or not lol. Good luck on the research hmm maybey they can help you here if you post the question.I was poking around at shotguns and ran across one with a pistol grip. Loved it, but can it take the sights from a Benelli M4? Anyone wanna school me on it? Not snagging one for quite a while, but just like to research.
