Benelli 12621 Ethos SuperSport A.I. 20ga 28" Carbon Fiber 4+1 Semi-Auto Shotgun

The Benelli ETHOS SuperSport A.I. 20-Gauge Shotgun 12621 is a high-performance semi-automatic shotgun designed for sporting and competitive use. It features a 28-inch carbon fiber barrel, offering both lightweight handling and durability. With a 4+1 capacity, this Benelli 12621 shotgun incorporates Benelli’s Advanced Impact (A.I.) technology for improved shot performance and precision. It utilizes the Inertia Driven System for reliable cycling and cleaner operation. Stylish and functional, the ETHOS SuperSport A.I. is built for shooters who demand speed, balance, and cutting-edge technology in a premium sporting shotgun.

The Benelli ETHOS Performance Shop Sport seamlessly blends refined aesthetics with cutting-edge performance. At its core is Benelli’s Advanced Impact barrel and choke system, engineered with precisely contoured ballistics to maximize energy transfer, velocity, and penetration, resulting in tighter shot patterns and greater downrange effectiveness. This barrel is further enhanced with Benelli’s Cryogenic Treatment, a process that relieves stress from hammer forging, creates a smoother internal surface, and helps the barrel stay cleaner longer.

Designed with the shooter in mind, the Benelli ETHOS Performance Shop Sport Shotgun features enlarged controls for easy manipulation and a custom, 6-ounce weighted forend cap to optimize balance and handling, making it ideal for competitive and high-volume shooting.

At the heart of the ETHOS is Benelli’s legendary Inertia Driven System. Consisting of only three main components—the bolt body, inertia spring, and rotating bolt head—this ultra-reliable mechanism uses the force of recoil to cycle the next round. Its simplicity means no adjustments are needed, and it handles everything from light field loads to heavy magnums with ease. Unlike gas systems, the Inertia Driven System keeps gas, smoke, and burnt powder out of the action, running significantly cleaner and more efficiently.
