I had to make a backsight leaf slide a few years ago, I had all the parts to the backsight except the slide with the studs. I took two attempts but I did complete the slide. I made the studs out of hardwood than cut the checkering. Each stud has a rectangular bar that engages the track on the leaf from the opposite side plus a small coil spring. I will take it apart sometime to show the home-made parts. In my photo the studs look too sharp and I have since sanded them down to look better.Attachment 98645
