The J.P. Sauer & Sohn Replacement Barrel for the Sauer 404 is a premium factory-original modular barrel built to bring hard-hitting .338 Winchester Magnum knockdown power to your switch-caliber rifle. Cold hammer-forged in Germany, this 620mm (24.4") barrel utilizes a standard 17mm contour taper to perfectly balance easy handling on arduous stalks with the structural integrity needed for magnum velocities. Designed for the S404 takedown chassis, its integrated six-lug breech lets you swap calibers or pack down the rifle using only the onboard Sauer Universal Key (SUS) tool, delivering a guaranteed return-to-zero upon reassembly. Finished with a weather-resistant nitrided coating and outfitted with high-visibility factory iron sights, its precise 1:12" twist rate is optimized to stabilize heavy hunting bullets, making it a supreme choice for large, dangerous game worldwide.
