The Ethos is an elegant new semi-automatic 12-gauge shotgun that is the culmination of Benelli's latest innovations, refinements, and design superiority, all centered around the core Inertia Driven System. The Ethos is built on a new platform that combines form and function for improved ergonomics, the ability to cycle the lightest loads (even 7/8 ounce), and a patented Progressive Comfort recoil reduction system that self-adjusts to any size load to provide less felt recoil. Ethos stocks are cut from beautifully figured AA-Grade European walnut and are designed specifically to incorporate the recoil reduction system. Every Ethos features a replaceable carbon fiber rib that reduces overall weight. The interchangeable front sight enables shooters to quickly switch between red, green, or yellow fiber-optics, which come standard. A newly patented anti-seize magazine cap incorporates a synthetic bushing in the magazine cap, preventing it from binding in foul weather or dusty conditions. Five Crio choke tubes are included (F/M/IM/C/IC).
