I made an up grade to the sights on both of my MK85's. I have been using them like I use the Lyman sight. I take a range finder get the range and set the sight for the shot. No hold over or under.
Well the FP sight had a screw to set the sight to keep it from being sloppy.
This is what the original set up looked like.



I added new screws with knobs that will allow me to loosen them set the sight and re tighten. I like the idea I don't have a loose screw in the sight to get lost, or an unknown amount of slop.
