Things You'll Need
Instructions
Use your small flat screwdriver to remove the plug screws located in the mounting screw holes. The function of the screws is to prevent moisture from getting into the screw-holes when they're not being used for mounting a scope.
Position your rail mount on the top of your shotgun and align the holes in the mount with the screw-holes in the shotgun.
Use the supplied screws to secure your rail mount to your shotgun. Your shotgun is now ready to accept weaver style scope rings.
