The Lyman 57 WJS receiver sight is designed to fit without contacting the stock or requiring a notch. These sights are equipped with "hunter" or "target" adjustable knobs.
The sights range in condition from NRA Good to NRA New, Old Stock, and are sold based on condition. An aperture is included but style may vary. Mounting screws are included.
We use the NRA Modern Gun Condition Standards Grading System for grading part conditions. You can read about it HERE
