I put the Williams peep on my 45-70 Handi. Only shot it once, but more is planned. You may need a higher front sight (available from NEF) to zero it (about $7.00 -needs bluing too). I initially set the peep by sighting through the peep and on through the original sights. The rear open sight will have to be removed after this. Using a fine punch (or a piece of thin music wire) take out the cross pin and catch the elevation spring. The mounting screw is now easy to remove. Save the parts for later.
By the way, the FP will be great for hunting, but the aperature is large for accurate paper punching.
