The J.P. Sauer & Sohn Standard Replacement Barrel for the Sauer 404 is a premium factory-original modular barrel chambered in the flat-shooting and highly accurate 6.5 Creedmoor caliber. Cold hammer-forged at their advanced manufacturing facility in Germany, this 560mm (22") barrel features a standard 17mm contour taper designed to blend fast-handling portability with exceptional sub-MOA precision. Purpose-built for the Sauer 404 modular take-down chassis, it features an integrated six-lug locking recess that ensures the bolt locks directly inside the breech ring. This system delivers extreme repeatable consistency and a perfect return-to-zero whenever the barrel is detached or swapped using the onboard Sauer Universal Key (SUS) tool, making it an ideal choice for hunters optimizing their setup for long-range precision or medium game hunting. Equipped with high-contrast factory open sights for rapid target acquisition in thick cover, its fast 1:8" twist rate is beautifully optimized to stabilize long, high-BC hunting projectiles over extreme distances.
