So I put a new scope on my AR-15 today, and was really surprised to find that the front site post, which is sticking up half way in front of the objective, is completely absent from the sight picture. I've been searching around for a basic scientific explanation of how this works, but I haven't been able to find anything. Does anyone have any links to good resources, or a good explanation of what makes this giant black steel obstruction disappear at magnification over 3x?
