Things You'll Need
Instructions
Point the rifle in a safe direction, then use the lever to open the chamber and confirm that you rifle isn't loaded.
Locate the retention screw on top of the rear sight. This is the same screw you loosen when making sight adjustments. Use your small flat-head screwdriver to remove this screw and lift the rear sight and the rear sight leaf off of the barrel.
Position your replacement sight onto the barrel then screw the retention screw back into position, securing your new sight to the rifle.
