I have a model 67 that I would like to put a rear aperture sight on. I looked at Lyman 90 MJT
and Williams FS models, but don't know if they will fit. As the barrel and receiver are one piece
the sight has to mount ahead of the bolt. It's only .800 - .820 inch up there and the mounts I've seen are for 15/16 and 1 inch. I have a 17A front to put on, but won't until I get a rear to
work. This is for a mini - palma (200yd) and old eyes need help. Any ideas?
