Sauer 404 Barrel .308 Win Heavy Contour 560mm 80105866

The J. P. Sauer & Sohn Heavy Contour Replacement Barrel for the Sauer 404 is a premium factory-original modular barrel engineered specifically for maximum thermal stability and match-grade precision. Cold hammer-forged in Isny, Germany, this 560mm (22") barrel features an expanded 19mm (0.75") heavy contour profile. The thicker steel wall slows down barrel heating and dampens parasitic harmonics, delivering highly uniform string consistency over extended firing sessions. Purpose-built for the Sauer 404 switch-barrel platform, it incorporates an integrated six-lug breech recess that locks the bolt directly into the barrel framework. This allows marksmen to easily detach the barrel or alternate calibers using only the forearm-housed Sauer Universal Key (SUS) tool while retaining a guaranteed return-to-zero. Treated with a highly durable, deep nitrided finish for absolute weather resistance, this heavy barrel features a precision-cut 1:11" twist rate optimized to stabilize heavy-grain projectiles, making it a supreme choice for blind hunting, long-range field observation, or precision competitive shooting.
