HIVIZ Magnetic Base Fiber Optic Front Sight for Shotguns with .328" to .437" Vent Rib

The Hi-Viz Magnetic Base Fiber Optic Front Sight brings visibility and quick-change flexibility to your shotgun's vent rib. This sight uses a snap-on/off magnetic mounting system that grips securely without altering your barrel, making it ideal for shooters who want a reliable sighting solution that won't interfere with your gun's profile or require permanent modification. The magnetic base accommodates vent ribs from .328" to .437" wide, fitting a solid range of popular pump and semi-auto shotguns from Winchester, Mossberg, Browning, and Beretta.

What sets this sight apart is the interchangeable LitePipe system. The M-Series includes four high-intensity fiber optic LitePipes, letting you dial in the brightness that works best for your hunting or sport shooting conditions—from low-light cover to open-field daylight. The S-Series offers a more economical single LitePipe option, available in green or red. Either way, you're swapping fiber optics without tools or fuss, adapting to whatever light you're hunting in without changing your sight body.

Fiber optic sights cut through the noise in your peripheral vision and concentrate your sight picture where it matters. On a shotgun, where quick target acquisition is the name of the game, that advantage pays dividends over traditional metal beads. The compact design keeps your gun balanced and doesn't crowd your rib line, and the magnetic attachment won't rattle or loosen as you move through brush or across uneven terrain.

Note: This sight will not fit fiber or aluminum ribs—stick to standard steel vent ribs within the .328" to .437" window for guaranteed compatibility.

Frequently Asked Questions

Will this sight fit my shotgun's vent rib?

The Hi-Viz magnetic base is designed for ribs between .328" and .437" wide. It's compatible with most Winchester post-1964 pumps and autoloaders, all Mossberg models (except ported variants), Browning Citori target grades (except super wide ribs), and Beretta S682 Comp trap guns. It will not fit fiber or aluminum ribs—only standard steel. If your rib width is outside that range or made of aluminum or fiber, this sight won't work for your gun.

What's the difference between the M-Series and S-Series versions?

The M-Series includes four interchangeable high-intensity LitePipes so you can adjust brightness to different light conditions. The S-Series is more economical and includes a single LitePipe in your choice of green or red, giving you one fiber color optimized for your typical hunting or shooting scenario.

Does the magnetic base require permanent modification or tools to install?

No. The sight uses a snap-on/off magnetic mounting system that grips your vent rib without tools, drilling, or permanent changes to your shotgun. You can remove it as easily as you attach it.

Can I swap LitePipes between different light conditions?

Yes—if you choose the M-Series. Four interchangeable LitePipes let you change fiber color and brightness as conditions shift. The S-Series comes with a single LitePipe in green or red, so you get one option without the flexibility to swap.
