A few days ago I purchased a used Lyman 57 peep sight for my .54 GPR. Due to vision problems (old eyes) the buckhorn sight was simply not going to cut it. A wedge and screw came with the sight. Made a trip to town this morning and picked up a drill and a tap. Back home I first marked the proper location for the one hole I had to drill and tap. Then it was disassemble time, pulled the tang, took one more measurement and placed on X over the center of the hole location. Everything went well. I did have to add one shim to get it level.
The sight came with what I believe was a .40" aperture. Well, that wasn't going to cut it either. I do not know the exact size of the aperture in my TC peep but its pretty big, and it flat out works awesome in the darker woods. Didn't have a drill bit that size so I had to drop down some to drill out the .40 thousands aperture in my Lyman sight to 107 thousands. Walked out back and took aim at a stump down the hill in the darker woods. I would reckon its about 80 yards down there. Its going to work out great. Clear sight picture and I can still easily center the front bead in the aperture.
I also reinstalled the TC peep on my New Englander.
I plan on making a trip to the range tomorrow where I can get some farther distances and get them both zeroed in.
