The Williams Fire Sight Set (brand part no. 66370) is built to upgrade the factory sights on most Mossberg 500 and 835 shotguns that already have a factory-installed Williams rear sight. Constructed from metal, this fire sight set drops in as a direct sight upgrade, giving shotgun owners a brighter, faster sight picture for turkey hunting, slug shooting, or home defense use without a full sight-system swap.
