My '70s Win 94 wears a Weaver side mount on the left side and a Williams 5D on the right.
My Marlin XS7 just got drilled and tapped for a Williams FP ( front sight is .850"

My BLR takedown has an XS Low Weaver Backup ( again, very tall front sight, Skinner patridge). I removed the lower recoil pad screw and added a pin to the stock. I can now just lift the lower edge of the recoil pad and twist the pad to retrieve the sight from the hollow already in the stock for the stock bolt.
My AK has a TWS Dogleg Rail rear cover we just drilled and tapped 8-40 for a Skinner Lo-Pro
My Ruger 10/22 also wears a Skinner Lo-Pro we just drilled and tapped into the rear wall of the receiver and a flat milled for the lock screw.
What do you do on your scoped guns?
