Hiviz S400R S-Series Shotgun Front Sight Magnetic Rib .328-.437" Red LitePipe

The Hiviz S400R is a magnetic shotgun front sight from Hiviz's S-Series, designed to snap securely onto the rib of a shotgun using powerful rare-earth magnets. No bolting or gunsmithing is required; the sight holds firmly in place on the rib while giving the shooter a bright, fast-pickup aiming point.

This Wide Model fits shotgun ribs from .328" to .437" (21/64" to 7/16", or 8.3mm to 11.1mm), making it compatible with most sporting and tactical shotguns with that rib width, including Winchester post-1964 pumps and autoloaders. The sight body is molded from lightweight polymer for durability without adding noticeable weight to the barrel.

At the core of the sight is a bright red fiber-optic LitePipe that gathers ambient light to deliver a clear, high-visibility aiming reference in daylight. The LitePipe is field-replaceable, so the sight can be refreshed or swapped without replacing the entire unit. Hiviz backs this sight with a Limited Lifetime Warranty.
