The most effective and usable solution for mounting offset sights. Stop mounting your back-up sight underneath of your primary optic! What is the point of back-up sights that you cannot use unless you unscrew and remove your primary optic? Removing your primary optic is completely impractical for any tactical situation you find yourself in.
This adapter was designed specifically for rifles with mounted optics preventing the back-up sights from being useable, and it is perfect when your primary optic has a short eye relief and is best mounted at the rear most portion of your rail. That’s because this mount doesn’t require a rail slot! You can even use it to mount a smaller secondary sight like a red dot sight offset to your primary sight for close quarters conditions.
