HiViz M400 Magnetic Shotgun Front Sight
The HiViz M400 represents a practical solution for shooters who demand flexibility in their shotgun setup. This magnetic front sight system delivers quick installation and removal without permanent modifications to your firearm.
Key Features
- Magnetic snap-on/off design for tool-free installation and removal
- Wide rib compatibility fits .328" to .437" rib widths (8.3mm to 11.1mm)
- Interchangeable fiber optic LitePipes in red and green for varying light conditions
- High-visibility two-toned fiber design for rapid target acquisition
- No permanent modifications required to your shotgun
Compatibility
The M400 is engineered to fit:
- Winchester: all post-1964 pumps and autoloaders
- Mossberg: all non-ported models
- Browning: Citori target grades (except super-wide ribs)
- Beretta: S682 Comp trap guns
What's Included
Each M400 sight comes with four interchangeable LitePipes—two red and two green—allowing you to optimize visibility for morning fog, bright sunlight, or overcast conditions. The two-toned fiber design enhances contrast and speeds up sight picture acquisition when it matters most.
Design Considerations
The magnetic base system is not compatible with fiber or aluminum ribs. The M400 is specifically designed for standard steel ribs within the specified width range. This straightforward approach ensures reliable performance without the complexity of universal systems that compromise on fit or function.
