This is a vintage sight block for the front sight position on heavy barreled model 70 rifles which do not have a front sight dovetail. These blocks are designed to accommodate globe-style removable target sights such as the Lyman 77. They will not accommodate sights such as the Lyman 17 that require a dovetail slot in the barrel. Blocks are vintage used parts in very good to excellent condition. No screws are included.
