I bought an old J.C. Higgins model 45 levergun in 35 Remington. This gun has a non-folding rear sight. It is already drilled and tapped on the top and side of the receiver. I wanted to put a Williams peep sight on it, but I'm worried that, even with the ramp removed, the rear sight will be in the line of sight. Also, I'm not sure if the height of the current front bead will work with a rear peep. I could avoid this whole mess by scoping the gun, but I'd like to try the peep sights first. Any thoughts?
