HiViz PM1002 CompSight Bead Replacement Front Sight - Black | Green/Red/White Fiber Optic

The HiViz PM1002 CompSight is a fiber optic front sight replacement that trades the factory bead for a glowing dot visible in dim light and bright sun alike. Built on a steel base that screws directly onto your shotgun's rib, it uses light-gathering polymer rods to create that classic HiViz glow—no batteries, no button pushing, just optics doing what they do best. If you shoot shotgun competitions, law enforcement courses, or hunt in varied light, this upgrade is one of the easiest ways to improve your sight picture without changing your gun's profile or your shooting style.

What makes the CompSight genuinely useful is the flexibility. HiViz includes eight interchangeable light pipes in three colors (red, green, and white) across four different diameters, so you can dial in the brightness and size that works best for your eyes and your shooting conditions. The steel mounting base and included screws handle nearly all modern shotgun ribs, and everything stores in a rotary carrying case that keeps your spare pipes organized and the spring release key handy when you need to swap them.

Setup is straightforward: the sight screws onto your existing rib in minutes. Once it's mounted, you can experiment with different light pipe combinations to find what gives you the fastest target acquisition and clearest sight picture for your shooting. No gunsmithing, no permanent modifications—just an effective upgrade that you can adapt to your shotgun and your conditions.

Frequently Asked Questions

What shotgun ribs does the CompSight fit?

The HiViz PM1002 is designed to work with most modern shotgun ribs using the four mounting screws provided. However, shotgun rib designs vary—verify compatibility with your specific gun before ordering, or contact our team if you're unsure about your rib type.

How do I choose which light pipe diameter to use?

The four diameters (.090", .110", .120", .135") let you adjust the brightness and size of the aiming dot. Smaller pipes appear dimmer and tighter; larger pipes glow brighter and cover more of your sight picture. Try different sizes during practice to see which gives you the fastest sight acquisition for your shooting style and conditions.

Do I need batteries or electricity for the fiber optic sight to work?

No. The HiViz CompSight uses passive fiber optic technology that gathers ambient light naturally—no batteries, no charging, no electronics to fail. The light pipes glow based on the available light around you, so they work in any lighting condition without extra gear.

What's included in the box?

The PM1002 comes with the steel sight base with mounting hardware, eight interchangeable light pipes (red, green, and white in multiple sizes), four mounting screws to fit most shotgun ribs, and a rotary carrying case for storing and transporting your spare light pipes and the spring release key.
