This is the most innovative sight to come along in quite a long time. Throw away those old notch and aperture sights and use the most advanced and simplest sight around. You will be amazed how easy it is to line up the front dot over the bar. Just like dotting the letter "i". It will give you the clearest sight picture with the simple rear post. It's almost as easy as pointing your finger. You will be able to see more of the target and come back down to alignment for faster followup shots.
