"The Benelli ETHOS Sport Semi-Auto Shotgun is an elegant shotgun that blends traditional good looks with Benelli's time-proven technologies. The heart and soul of the ETHOS is the Inertia Driven System that's capable of cycling everything from the lightest target loads to the heaviest 3"" magnums quickly and without modification. The nickel-plated receiver and gloss blued barrel look great with the AA-grade satin walnut stock and forend. The Progressive Comfort recoil reduction system inside the stock features flexible buffers that flex to take the sting out of heavy magnum loads. Red fiber-optic front sight.
