The Lyman 57 WJS receiver sight is designed to fit without contacting the stock or requiring a notch. These sights are equipped with "hunter" adjustable knobs.
The sights range in condition from NRA very good to NRA excellent. This means they may have minor bluing wear, but will have no damage or functional problems. The sights shown here are an accurate representation of the sight you will receive. 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
