Benelli knows that hunting can take you to some very unforgiving environments that wreak havoc on metals, so they developed BE.S.T. technology to protect your shotgun with a rugged coating to put an end to corrosion and rust. BE.S.T. is applied in an environmentally friendly, high-vacuum, radio-frequency plasma technology that bonds the diamond-derived Benelli BE.S.T. surface treatment to the metal components. In fact, it's so effective, Benelli warranties treated parts against corrosion and rust for 25 years. The ETHOS shotgun line from Benelli is the elegant, reliable series that culminates Benelli's latest innovations, refinements, and design superiority. All this is center around its core Inertia Driven System. ETHOS shotguns feature a beautifully figured AA-grade walnut stock, improved ergonomics, and a two-part carrier latch for quick and easy loading. ETHOS shotguns are the perfect combination of the latest technologies and the traditional style you've come to expect from Benelli.
