Benelli's Super Black Eagle II Semiautomatic Shotguns set the standard by which other semiautomatics are judged. Proven Inertia Driven® bolt mechanism shoots 2-3/4", 3" and 3-1/2" shells without adjustment. The ComforTech™ system reduces recoil up to 48% and muzzle climb by 15% without moving parts or extra weight. In fact, the SBE II weighs 13% to 15% less than similar shotguns.
