The HiViz S300-G Narrow Magnetic Shotgun Sight provides a bright green front-sight reference for shotguns with compatible ventilated ribs. Part of the HiViz S-Series, this model fits ribs measuring .218" to .328" wide (5.5–8.3mm), making it suitable for shotguns that require a narrow magnetic sight rather than an ultra-narrow or wide model.
The green fiber-optic LitePipe gathers available light to help make the front sight easier to see against the target and surrounding background. The S-Series is designed for shooters who already know their preferred sight color and want a straightforward sight without interchangeable LitePipes. The green LitePipe is fixed and cannot be replaced with another color.
The magnetic snap-on base allows the sight to attach to a compatible shotgun rib without replacing the factory front bead. Before ordering, measure your rib carefully to confirm the width falls within the S300-G's specified range. Choosing the correct rib-width model is important for proper fit and retention.
