The J.P. Sauer & Sohn Fluted 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 utilizes clean longitudinal fluting lines to significantly reduce overall weight, increase structural rigidity, and rapidly maximize cooling surface area during long courses of fire. Purpose-built for the Sauer 404 modular take-down chassis, it features an integrated six-lug locking recess that locks directly inside the breech ring for extreme repeatable consistency and an absolute return-to-zero when swapped with the onboard Sauer Universal Key (SUS) tool. This high-end configuration features a metric M15x1 muzzle thread pre-outfitted with a factory-tuned muzzle brake to noticeably diminish recoil push, maximizing downrange precision over extreme distances.
