It makes the front sight clear and takes the place of the rear sight although you can still look through the rear sight. Since the front sight being in focus is what is important it makes a huge difference in being able to shoot with confidence. It does the same thing as an installed peep sight and that is making your focus clear when looking through a small hole, you really should not be focusing on your rear sight anyway, it is just to line you up with your front sight. Rear sight blurry, front sight clear. Just a suggestion to save you money and keep your flintlock traditional.
