The HiViz PMN301 LiteWave H3 CompSight is designed for shotgun owners who want a visible front sight in both daylight and low-light conditions. Combining HiViz fiber-optic LitePipe technology with fully encapsulated tritium, this sight provides 24-hour illumination without relying solely on available ambient light.
The green front sight is housed in a low-profile, all-steel base designed to replace the factory bead on most vent-ribbed shotguns with a removable front bead. Its rugged construction makes it suitable for hunting, competitive shooting, and other applications where a durable, easy-to-see front sight is important.
The PMN301 includes five mounting screws in different thread sizes to accommodate a wide range of compatible shotgun bead mounts. Before installation, identify your shotgun's existing bead thread and verify that the supplied hardware is compatible. This is a screw-attach sight, not a magnetic rib-mounted model.
