Sauer 404 Barrel .300 Win Mag 620mm 80106824

The J. P. Sauer & Sohn Replacement Barrel for the Sauer 404 is a premium factory-original modular barrel chambered in the flat-shooting and hard-hitting .300 Winchester Magnum caliber. Cold hammer-forged in Isny, Germany, this 620mm (24.4") magnum-length barrel features a standard 17mm contour taper, engineered to maximize powder burn efficiency and muzzle velocity while maintaining a balanced, fast-handling profile. Purpose-built for the Sauer 404 switch-caliber platform, it features integrated six-lug locking recesses that lock the bolt directly into the breech. This system allows hunters to break down their rifle or swap calibers using only the forearm-housed Sauer Universal Key (SUS) tool, guaranteeing an absolute return-to-zero upon reassembly. Outfitted with high-contrast factory open sights for rapid target acquisition in thick brush, this durable nitrided barrel features a factory-specified 1:11" twist rate, providing exceptional long-range accuracy and knockdown power for large big game downrange.
