Evolution Gun Works Fiber Optic Front Sight Kimber .150 w/Green/Red Rod Steel. They are fully machined from tool steel and drilled for a fiber optic rod. Two unique factors of these sights are that they are not drilled through leaving a cleaner look in the front of the sight and they are supported in 3 different places. The Standard Dovetail depth is .070" and .330" wide. The Novak Dovetail depth is .075" and .330" wide. The Para Blank is machined to match Para?s front sight cut. The Kimber Blank fits both Kimber and Springfield sight cuts. NOTE: When installing the fiber optic rod use a small dab of crazy glue where the rod will touch the middle support of the sight. Do not put glue on the front support or the back support as it will be much more difficult to uninstall/reinstall the rod for future modifications. Each sight is supplied with 1 green and 1 red fiber optic rod.
