Series 17a Insert Set

The Lyman Series 17a Insert Set is a precision sight accessory designed for shooters who demand flexibility and accuracy across multiple shooting disciplines. This eight-piece insert system transforms the Lyman 17 globe sight into a versatile tool capable of handling benchrest, target, and field shooting scenarios. Whether you're zeroing a new rifle, competing in precision matches, or fine-tuning your sight picture for hunting, this insert set provides the optical options needed to optimize your sight performance in any lighting condition.

The Series 17a Insert Set includes eight carefully selected inserts engineered to deliver distinct aiming reference points: two post-type inserts in .050" and .100" widths for varied sight-picture preferences, one precision bead insert (.062" diameter) for close-range shooting, and five aperture-type inserts comprising one plastic aperture with a .120" hole for general use and four steel apertures with smaller openings for maximum precision at distance. The combination of post, bead, and aperture designs allows shooters to select the optimal sight geometry for their specific application, lighting conditions, and target distance. Steel inserts provide durability and precise optical performance, while the plastic option offers versatility for transitional shooting scenarios.

Competitive shooters, hunters, and precision rifle enthusiasts benefit most from this modular approach to sight tuning. The insert system's lightweight design (0.06 lbs) makes it practical for both range work and field carry, while the interchangeable format eliminates the need for multiple sight assemblies. Direct compatibility with the Lyman 17 globe sight platform ensures tool-free installation and immediate functionality. This set is ideal for shooters seeking to maximize their existing globe sight investment or those building a dedicated precision rifle setup that demands professional-grade aiming optics.
