The Hi-Viz S400 Wide Magnetic Shotgun Sight (brand part number S400G) is a snap-on front sight that clamps to a shotgun rib with a magnetic base instead of drilling or gluing. Four interchangeable high-intensity LitePipes ship with every M-Series sight so a shooter can match the fiber to changing light conditions, though this S-Series model comes set up with a single green LitePipe at a more economical price. The magnetic base is sized for ribs from .328 to .437 inch (21/64 to 7/16 inch, 8.3 to 11.1mm), covering post-1964 Winchester pumps and autoloaders, most Mossberg shotguns except ported models, Browning Citori target grades other than super-wide ribs, and the Beretta S682 Comp trap gun. It is not compatible with fiber or aluminum ribs.
