Authentic Kensight Sights - The Professional's Choice This is an authentic Kensight sight and not to be confused with other brands. When it comes to durability and features the Kensight sights far exceed our competitors. Our sights are Wire-EDM machined from a single billet of 4140 chrome-moly steel. The result is a precision sight built with better materials and the Wire-EDM construction ensures the tightest tolerances possible. This translates to ultra-smooth adjustments audible clicks for both windage and elevation and consistent dovetail dimensions in which the "industry standard" CNC construction cannot compete.
