Lyman 17AHB Target Front Sight .404" Height

This precision front sight is machined from a solid steel piece for rifles requiring a .404 inch sight height. It mounts securely into standard 3/8 inch dovetail slots. The unit includes eight interchangeable inserts locked by a threaded cap. It suits target shooters and gunsmiths building or repairing competition rifles.

Dovetail mounting frees up sight-radius options

Installation requires a compatible 3/8 inch dovetail cut on the barrel or rib; no other mounting interface is supported. The threaded cap secures inserts without additional tools once the sight body is fitted. Builders needing a different sight height or a clamp-on base cannot use this model. Export outside the United States is prohibited by State Department regulations.
