The TriStar Arms Viper G3 20 gauge walnut semi-auto shotgun (brand part no. 26102) pairs a 28-inch barrel with a gas-operated action and a wood stock. At an average 5.9 lbs it is a light gun to carry, and the 20 gauge chambering keeps recoil moderate for upland hunting, dove fields and sporting clays. The stock is high-grade Turkish walnut with cut checkering and a semi-gloss finish, and the receiver is Cerakote-finished. It is the wood-stocked 20 gauge in the Viper G3 line, built for shooters who want a lighter autoloader without giving up a traditional look.

Key Specifications

• Gauge is 20 gauge, a lighter-recoiling gauge that suits youth, smaller-framed shooters and long days in the field.
• Barrel length is 28 inches, a long barrel that smooths the swing on doves, quail and clays.
• The action is gas-operated semi-automatic, and the bolt stays open after the last round is fired.
• The tubular, bottom-loading magazine holds five rounds, with a shot plug installed that unscrews with the magazine cap.
• Three Beretta/Benelli Mobil-style choke tubes (improved cylinder, modified and full) come with a choke box and wrench.
• The front sight is a fiber optic bead on a vent rib with a matted sight plane, which cuts glare and picks up the bird quickly.
• The primary safety is a crossbolt safety on the back of the trigger guard, where it blocks the trigger and hammer.
• Average weight is 5.9 lbs, which you will notice in how the gun carries and swings.
• The barrel and chamber are chrome-lined, which resists corrosion and wipes clean after a wet day afield.
• The stock is Turkish walnut with cut checkering and a semi-gloss finish, finished with a rubber recoil pad and shim kits for fit.
