The Winchester SX3 Carbon Fiber Sporting Shotgun is the ideal firearm for a competitive day at the range. It offers an extremely fast cycling speed for an instant response on your shots. The self-adjusting Active Valve ensures speed, recoil reduction, and durability in all conditions. The .742" back-bored technology provides optimum shot patterns that are dense and even. For extra durability, the SX3 Sporter's bolt, carrier, slide, and cocking handle are nickel plated and its bore and firing chamber are chrome plated. An Inflex Technology recoil pad effectively absorbs recoil, allowing you to stay on target with fluid follow-through shots all day. TruGlo Tru-Bead fiber-optic front sight with interchangeable light pipes. Includes five Invector-Plus choke tubes (skeet, improved cylinder, modified, improved modified, and light full), two length-of-pull stock spacers, and drop and cast adjustment spacers. Chambered for 2-3/4" shells only. Lightweight black carbon fiber composite stock. Four-round magazine.
