The TriStar Viper G3 20 Gauge Semi-Auto, TrueTimber Atera, 26-Inch is a gas-operated 20 gauge semi-auto shotgun in TrueTimber Atera camo, built for upland birds, small game and the dove field (TriStar part no. 26135). It carries a 26-inch barrel with a vent rib and a fiber optic front sight, and it cycles light target loads through heavy 3-inch loads without any adjustment. The Viper G3 platform was tested to 5,000 rounds for endurance, and the receiver, chrome-lined chamber and barrel are built for a field gun that gets used hard. TriStar Arms makes the Viper G3 as a value-priced workhorse, and the camo finish means the gun arrives ready for the blind or the bird field.

Key Specifications

• The gauge is 20 gauge, a lighter-recoiling bore that suits upland birds and shooters who want less kick over a long day.
• The barrel is 26 inches long with a vent rib and matted sight plane, which keeps the sight picture clean on a moving bird.
• The action is gas-operated semi-automatic, which tames recoil and lets one gun shoot light target loads and heavy 3-inch loads interchangeably.
• The chamber is 3 inches, so the gun takes everything from light field loads to 3-inch magnum shells.
• Capacity is a 5-round magazine plus one in the chamber, with a shot plug included and installed for a bottom-loading tubular design.
• Three Mobil-style choke tubes (improved cylinder, modified and full) come with a choke box and wrench, so patterns are easy to tune to the game.
• The front sight is a fiber optic bead, quick to pick up against the rib in low light.
• The safety is a crossbolt safety at the rear of the trigger guard, which blocks the trigger, hammer lever and hammer when engaged.
• The finish is TrueTimber Atera camo, a field pattern that breaks up the gun against cover.
• Average weight is 6.1 pounds, light enough to carry all day and to swing smoothly.
