    I have had one of Shooting Sights reduced apertures for a long time, life and procrastination aside this one part sort of morphed into a collection of parts then into a complete rifle build….. You know how that goes… Anyway it got installed into my new build and at 49yo I’ve been blessed good vision for the most part but time waits for no man. This reduced hooded aperture has increased my depth of field and the front sight is super clean and crisp, I will not make the claim of having young 18yo eyes again but having the vision of a 22yo again feels very good and isn’t a far stretch. So “Yes” it works that good!

    Thanks, Shooting Sight for the new spec’s!
