The Novak Mega Dot Fiber Optic Dovetail Front Sight fits a .330" x 65 degree x .075" Novak front sight dovetail cut. The fiber optic rod is larger for superior light gathering and added strength. The front of the sight is recessed and the sides are shielded to prevent damage to the fiber. The edges are beveled to be snag free and the brightness of the fiber gives a fast daytime sight picture for use with concealed carry. Works extremely well with the Novak Super wide notch rear sight. Installation instructions included. Available in green or red.
