Hear you Mike, I am moving ahead on a slow bell. Todays examination of the screws shows the KROIL is doing its job. The front screw is moving in both directions about 1 turn. The rear adjustment screw moves about 1/2 turn in either direction. Now I am wondering just how loose should these adjusting screws move. Are they spring loaded (keeps tension on screw so as to not back off?) or will the close tolerance of the parts keep everything in place after sights are adjusted?
