I purchased what I think is a Benelli Nova Rifled Slug Barrel with Cantilever the model number on the box is 81055. The question that I have is that there is really no information on the barrel except for 12 Ga. 3 inch Made in USA. Does anyone know what should be on the barrel? I want a true Benelli barrel, not one from another manufacturer made for a Benelli Nova shotgun. Any help would be greatly appreciated.
