Maybe I should start offering some rear sight "kits". I usually start by milling a piece of low carbon steel, 12L14, and make a strip which looks like an upside-down "T", with the base being about 1/2" long and the sight portion about 1/4"
high. The base is usually about .100 thick, the upright portion is about the same. I then saw off a portion wide enough
for the sight I want, then clean up the sides with a file. I then put the sight back in the mill and, using about a 3/8" end
mill, will then mill out that little radius in front of the blade, where the sight slot goes. I then turn the sight over and hold
the sight blade in the vise and using a dovetail cutter, will cut the angles on both ends. After I install the sight on the
barrel I will round off the front and rear portion of the base, file a few neat notches in the front part, and it's ready to be
browned or blued, whatever..............Don
