The Lyman 66 Receiver Peep Sights bring a classic precision upgrade to lever action rifles like the Marlin 336. Built around a rugged black aluminum frame with a finely marked elevation scale, this receiver-mounted peep sight offers repeatable adjustments and a clean, uncluttered sight picture that helps shooters get the most out of their rifle’s inherent accuracy.

Designed specifically for flat-top receivers, this model features 0.25 MOA micrometer adjustments for both windage and elevation, allowing careful zeroing for hunting or range work. Two interchangeable aperture discs let you tailor the sight to changing light and target conditions, making it equally at home on the bench or in the field. Lyman’s long-standing reputation for dependable, shooter-focused designs is evident in every click and line of this sight.
