for me just will not work. I have an astigmatism that prevents me from seeing the front sight. I have to wear corrective lens to be able to see through the peep sight. I have learned to find the front sight (the new fiber sights are great for me) and then the notch in the buckhorn sight. I have three marlins but have put optics on all of them due to the before mentioned astigmatism. WB, the optics of the aperture sight is caused by light diffracting from the edge of the ring of the round aperture. If you are up to getting a good nights sleep, start with looking up Joseph B. Keller's published paper from 1961 on the Geometric Theory of Diffraction and then his paper on the Uniform Theory of Diffraction. LOTS of math etc. and guaranteed to put you to sleep, unless you like to read these papers. BTW, the F117 was based on the the GTD as well as other parts derived from Maxwell's equations. Sleep well and may the farce be with you......
