"The Stoeger M3020 Walnut-Stock Semi-Auto Shotgun uses the reliable Inertia Driven action to cycle either 2-3/4"" or 3"" 20 gauge shotgun shells without adjustment. The satin walnut stock gives the gun a classically styled look, while the barrel and receiver's durable Cerakote burnt-bronze finish does not glare to spook wary game. A ventilated, stepped rib and fiber-optic front sight allow for quick target acquisition, even in low light. Standard features include a shim kit to provide shooters with optimum fit, and 3 screw-in choke tubes and wrench. Choke tubes included: IC, XFT, and M. Sling swivel studs on the stock and forend cap offer an attachment point for a carry sling. The Stoeger M3020 is an ideal semi-automatic shotgun for a wide range of applications, from extreme-weather duck hunting, to spring turkey hunting, to shooting pheasants over corn stubble. 20-gauge semi-auto shotgun Reliable Inertia Driven action Cycles 2-3/4"" or 3"" Satin walnut stock and forend Cerakote burnt-bronze finished barrel and receiver Stepped rib and fiber-optic front sight"
