These sight slot blanks fill the rear sight dovetail when the sight is removed. This was done in the Winchester factory for rifles fitted with a receiver sight and is also helpful for creating additional objective clearance when installing a scope.
These blanks are vintage parts of unknown brand, in functional condition. May have finish wear and tooling marks.
