I am in need of a rear sight to replace one that is missing from a Tingle rifle. It has two holes for mounting, approx. 0.73” apart and no dovetail. I’m thinking if I could find a sight like the one pictured but not pre-drilled, that would be the way to go, but the spacing is not correct on that one and the only other rear sights I’m finding are dovetailed. If anyone has other suggestions, I’d appreciate it!
