here are c two pics both inexpensive sights. I just can't do $500 for s good sight for now. The elevation may only get changed couple times a year if tgat, for fun. Which one? I think the Marbles would be nice.
Figure on changing out front sight with a taller one. I get rid of the rear/mid barrel buckhorns or what ever you name them. 3 have peeps on receiver and on a 1892 has a tang. All lever rifles with peeps needed a taller front sight. As I recall so did the tang sighted 1892. The peeps and or tang sights will improve accuracy and easier on your eyes.
