Well, after both the front sight and the rear sight arrived, I installed a vise on my workbench, and replaced the sights. Front was no problem, rear was messy, and had to be cut out with a dremel. The Lyman 16A drove in right to left, the opposite of the factory. Changing the sights was frustrating, to say the least. However, I got them changed out. Got out to the range today, ammunition was Hornaday SST 150 gr. Distance was approx 50 yards, my backup sight distance (I will twin zero with a marble tang). The first few I was really trying, the rest, well, I was so thrilled to see it work I was just pumping the lever away and having fun with Arthur's rifle. The first picture is the Lyman rear installed, the second is the front that was on and my new sight in the right, (old, 0.361", 0.461") and the third is the group from today. http://i36.photobucket.com/albums/e1/1950OP/IMG_1181_zps8pvuc7wa.jpg

A very big thanks to the forum for all the help, I could not have done it without you!!!!
