TriStar 26114 Viper Gen3 20 Gauge Semi-Auto 3" 5+1 28" Matte Blue Vent Rib Barrel, Matte Blue Aluminum Receiver, Fixed Black Synthetic Stock The TriStar Viper Gen3 pairs 20 gauge chambering with a 28-inch barrel and black synthetic furniture. Its semi-automatic action is paired with a 3-inch chamber and a stated 5+1 capacity. The Matte Blue/Black appearance is a defining detail of the configuration. The vent-rib barrel provides a defined sighting plane along the top of the barrel, an important visual feature when evaluating a shotgun's sight arrangement. A fiber-optic sight supplies the front aiming reference, while the three supplied chokes give the package its stated choke selection. The matte blue barrel and aluminum receiver are paired with black synthetic furniture. This identifies the finish of the metal components separately from the stock material and color.
