Carlson's high quality accessory shotgun barrels are made for Benelli SuperNova and Nova models. All barrels are constructed from certified ordinance grade 4140 steel with chrome lined bores. Vent rib models have a satin matte blue finish with red fluorescent front sight and brass center bead. Barrels come with a Carlson choke tube, manufactured from 17-4 stainless steel except for the rifled choke tube models which are made from 304 high stress stainless steel, installed. All of our Benelli replacement barrels are threaded for the Benelli Mobil choke style system. *Note- For Benelli Nova & Super Nova, 12 gauge only, right hand only.
