Lyman Series 17A Target Front Sights

• Interchangeable insert system: The Series 17A uses eight interchangeable inserts, letting the sight picture be tailored to different targets, lighting conditions and shooting disciplines without changing the whole front sight.
• Solid steel construction: A steel body gives the sight the rigidity needed for repeatable alignment and dependable service on rifles used for regular target work.
• Fixed front-sight design: With a fixed, non-illuminated front sight, the setup stays simple and consistent, which helps shooters focus on sight picture and hold rather than extra adjustments.
• Dovetail mounting format: The sight is built for 3/8" dovetail slots, while the 17AEU version uses a .360" metric European dovetail, making it suitable for rifles that need this specific fit.
• Target-height options: The 17A series is offered in several heights, and this family includes the 17AEU .464 high version, helping match the front sight to the rifle and rear sight combination for a correct zero.

About the 17A Series

The Lyman 17A Series is a line of target front sights made for shooters who prefer a traditional aperture-based iron-sight setup on rifles used for target shooting, small-bore competition and other precision applications. Within Lyman’s sight lineup, the 17A sits as a practical companion to the company’s receiver sights, giving the shooter a front sight that can be tuned to the target rather than locked into a single blade or bead format.

A defining feature of the series is its interchangeable insert system. Instead of forcing one sight picture to suit every job, the 17A accepts multiple insert styles so the shooter can choose a post, bead or aperture arrangement that best matches the target size and background. The inserts are held in place by a threaded cap, which keeps the system secure while still making changes straightforward at the bench or on the range.

The series also follows a durable mechanical approach. Each sight is machined from a solid piece of steel, and the design is intended for dovetail mounting on the barrel. Different height options across the range allow the sight to be matched to various rifles and rear sights, which is important for obtaining a usable zero without compromising the clean, repeatable sight picture target shooters want.

About the Lyman Series 17A Target Front Sights

The Lyman Series 17A Target Front Sights are built for shooters who want a precise, adaptable front sight for a rifle fitted with a receiver sight. Rather than using a simple hunting-style bead, this design gives the shooter a more refined aiming reference that is better suited to deliberate fire on paper targets and other accuracy-focused work. The sight body is machined from solid steel, which helps maintain alignment and gives the assembly the sturdiness expected from a barrel-mounted iron sight.

What makes this model especially useful in practice is the eight-insert configuration. Different insert shapes allow the sight picture to be tuned to the target and the shooter’s preference. Aperture inserts can help frame a bull cleanly for precise centering, while post or bead options can be useful when a different visual reference is preferred. Because the inserts are secured by a threaded retaining cap, the system remains stable once installed.

This product family is designed for 3/8" dovetail slots, while the 17AEU variant uses a .360" metric European dovetail. The series also comes in several heights, including .404, .494, .584 and .464 depending on version, measured from the bottom of the dovetail to the center of the aperture. That range of heights matters because it lets the front sight be matched correctly to the rifle and rear sight, which is essential for proper elevation adjustment and a balanced sight picture.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, and the brand remains closely associated with traditional sighting systems and practical shooting equipment. Today, Lyman Products is headquartered in Middletown, Connecticut and focuses on equipment and accessories for shooting and reloading.

Its catalog extends well beyond sights, covering reloading dies, presses, bullet-casting equipment and gun sights. That broad specialization helps explain why Lyman has remained a familiar name among shooters who value mechanical simplicity and proven designs. In the sight category, Lyman’s tang and receiver sights continue to use principles from William Lyman’s original sight design, linking current products to the company’s early work in precision iron sights. The company also expanded over time through acquisitions, including the Ideal reloading-tool business in 1925, which reinforced its long-standing role in the reloading and shooting market.
