The J.P. Sauer & Sohn Replacement Barrel for the Sauer 404 is a premium factory-original modular component chambered in the versatile .270 Winchester caliber. Cold hammer-forged at their facility in Isny, Germany, this 560mm (22") barrel features a standard 17mm contour taper that offers a perfect balance of fast maneuverability and sub-MOA thermal stability. Engineered specifically for the S404 split-receiver takedown system, it features precision locking recesses that allow shooters to swap calibers or pack down their rifle using only the Sauer Universal Key (SUS) tool, consistently returning to absolute zero upon reassembly. Outfitted with high-contrast factory open sights for fast target acquisition, this nitrided barrel delivers exceptional corrosion resistance and a optimized 1:10" twist rate, making it an excellent choice for hunting medium to large game across varied field terrain.
