The TrijiDot Fiber Optic Shotgun Sight is made specifically to fit a .210-.280 inch wide barrel rib shotgun. Conveniently, this sight fits on some of the most popular shotgun brands, like Benelli and Winchester. This sight is designed to use ambient light to give the shooter a clear and bright point of light to aim at, even in low lighting conditions. The green fiber optic shotgun sight is topped with a sapphire jewel for protection and to evenly distribute the light that it is using. While this sight can be used in tactical and defense situations, it is also perfect for hunting applications as well.
