The J.P. Sauer & Sohn Replacement Barrel for the Sauer 404 is a premium factory-original modular barrel chambered in the highly versatile .308 Winchester caliber. Cold hammer-forged in Isny, Germany, this 560mm (22") barrel features a standard 17mm contour taper designed to blend fast-handling portability with exceptional thermal stability and sub-MOA precision. Purpose-built for the Sauer 404 modular take-down rifle system, it incorporates precision locking recesses that allow you to swap calibers or pack your rifle down into a compact case using only the Sauer Universal Key (SUS). The system delivers extreme repeatable consistency and a perfect return-to-zero upon reassembly. Equipped with high-contrast factory open sights for rapid target acquisition in dense cover, this durable, nitrided barrel provides an optimized 1:11" twist rate, making it an excellent all-around choice for big game hunting across any terrain.
