The Sauer S404 Bolt Head Magnum Right Hand is a factory replacement bolt head designed for the modular Sauer 404 rifle system. Crafted to handle high-pressure Magnum calibers (such as .7mm Rem. Mag., .300 Win. Mag., and .375 H & H), this right-handed component allows shooters to easily swap calibers or maintain their existing rifle platform. It features a robust, quick-release mechanism for toolless field stripping and caliber conversion, ensuring lockup strength and reliable extraction.
