Lyman 66 receiver peep sights are built for flat-receiver firearms and are known for crisp, repeatable adjustments. The system uses audible 1/4 minute click micrometer controls for elevation and windage, plus a quick-release slide for faster on/off use. Two interchangeable aperture discs let you switch between a larger hunting opening and a smaller target opening for different lighting and aiming needs.
