Lyman 57 Receiver Peep Sights

• Receiver-mounted peep design: Placing the aperture close to the shooter’s eye gives a longer sight radius and a naturally centered sight picture, helping improve practical accuracy over many barrel-mounted rear sights.
• Adjustable steel construction: The all-steel body and adjustable mechanism suit regular field use while allowing the sight to be tuned for different loads, distances, or shooting styles.
• Model-specific fit options: The Lyman 57 series is offered in variants for rifles such as Rem. 700, Win. 70, Sav. 110 or Mauser, Springfield, and White Systems, making it a practical upgrade for classic bolt-action platforms.
• Target-style sight picture: A peep sight promotes fast alignment of front sight and target without the bulk of an optic, which appeals to shooters who want a clean, traditional setup for hunting or range work.
• Made in the USA: Domestic manufacture supports the series’ long-established design approach and gives shooters a familiar option for restoring or upgrading traditional rifle sight systems.

About the 57 Series

The Lyman 57 Series is a long-running family of receiver peep sights built for shooters who prefer a precise iron-sight setup on traditional rifles. In Lyman’s sight lineup, the 57 series sits as a receiver-mounted option for bolt-action and similar platforms, offering a more refined aiming system than many basic open rear sights. Its design follows the classic peep-sight principle that has remained popular for hunting rifles, target rifles, and restoration projects where a scope is unnecessary or undesirable.

What distinguishes the series is its focus on practical adjustability and a clean, repeatable sight picture. By moving the rear aperture back to the receiver, the 57 series helps the eye center the front sight more naturally, which can make precise shot placement easier in real use. The series is also known for its steel construction and model-specific fitments for different rifle actions. For shooters working with older sporting rifles or military-pattern actions, the 57 line remains a relevant choice because it combines traditional handling with the finer control expected from a receiver-mounted rear sight.

About the Lyman 57 Receiver Peep Sights

Lyman 57 Receiver Peep Sights are intended for shooters who want the advantages of a receiver-mounted aperture sight on rifles that are still used with iron sights, whether for hunting, target shooting, or period-correct rifle builds. Compared with a barrel-mounted rear sight, the receiver position gives a longer effective sight radius and places the aperture close to the eye, which helps the front sight appear easier to center. In practice, that means a sight picture that feels cleaner and more deliberate, especially when careful shot placement matters.

This sight uses an adjustable rear assembly, allowing windage and elevation changes to be dialed in for a chosen load or distance. That matters on rifles chambered for different cartridges or used across varying ranges, because the shooter can tune the point of impact instead of accepting a fixed compromise. The steel construction adds rigidity and durability, which suits a part that may see repeated adjustment and regular field handling. Its black finish keeps the appearance subdued and appropriate for both sporting and classic rifle setups.

The 57 family is also practical because it is offered in several fitments. Variants include the 57WJS for Rem. 700, Win. 70, and Sav. 110, the 57SME for Mauser, Springfield, and White Systems, and the 57SMET version for the same platforms with target knobs. That makes the line useful both for restoring older rifles and for upgrading familiar bolt-action actions with a more precise iron-sight arrangement.

About Lyman

Lyman began as the Lyman Gun Sight Company in 1878 in Middlefield, Connecticut. The company built its reputation around shooting equipment and remains closely associated with gun sights and reloading tools. Its catalog extends across reloading dies, presses, bullet-casting equipment, and gun sights, reflecting a long-standing focus on practical tools for shooters and reloaders rather than a single narrow product niche.

The brand’s receiver and tang sights still reflect the principles behind William Lyman’s original sight design, which is especially relevant for products such as the 57 series. Over time, Lyman also expanded through related shooting brands and product lines, while keeping its core connection to traditional sighting systems and reloading equipment. Today, Lyman Products is headquartered in Middletown, Connecticut, and the company remains a familiar name for shooters looking for established iron-sight and workshop equipment.
