The TriStar Viper G3 20 Gauge 3-Inch Semi-Auto Shotgun with a 26-inch barrel and synthetic stock (TriStar part no. 26115) is the lightweight option in the Viper line. At a published 6.1 pounds average, it gives upland hunters and smaller-framed shooters a gas-operated gun that carries easily and tames recoil. TriStar fits it with a chrome-lined vent-rib barrel, a fiber optic front sight, and a soft-touch synthetic stock with a shim kit. It is a good fit for pheasant, quail and doves, as well as for clay shooters who prefer a lighter gun.
