This is for the southpaw (Lefty). Is's an original and new Benelli Part.
Benelli is the premiere provider of left handed waterfowling shotguns and the Benelli Super Black Eagle II is made to withstand the harshest conditions. But if you are changing your barrel it's because you had an accident and blew a whole into it.
This Benelli SBE 2 barrel is 28 inches for a 12 gauge chambered: 2-3/4", 3", 3-1/2"
