Sour exchange barrel 505/404 Heavy fluted

Fluted S404 exchange barrel with heavy contour. The heavy version of the Sauer 404 exchange barrel is equipped with a 19 mm barrel profile at the muzzle.
Sauer exchange barrels with heavy contour are approximately 300 g heavier than the standard barrels, making the repeater more front-heavy and providing better oscillation behavior of the weapon. Additionally, the inherent precision of the barrel increases, and the recoil of the repeater rifle is reduced.The fluting of the S404 exchange barrel significantly increases the surface area of the barrel. This allows the barrel to dissipate the heat generated during high shot sequences much more effectively. This prevents the annoying mirage above the barrel. The elegant aesthetics of the fluted barrel is convincing, as it visually integrates well into the overall appearance of the fine Sauer hunting rifles.Sauer also offers a wide selection of calibers for the S404 even with the heavy barrels, with up to three barrel lengths available with and without sights and M 17x1 threads, depending on the caliber group.The cold-hammered exchange barrels are manufactured at the Sauer location in Isny in the Allgäu, thus they are "Made in Germany"The barrels, made from a specially developed steel, are plasma-nitrided and have a hardened coating of 0.1 mm thickness. Inside, a soft steel core remains. This results in each barrel oscillating optimally and shooting very precisely. Therefore, Sauer guarantees a precision of under one MOA.To protect against corrosion, the Sauer exchange barrels are additionally blued.Sauer divides into four caliber groups with the following available calibers and barrel lengths:Mini: .222Rem, .223RemBarrel length: 56 cm (optional short barrel length: 51 cm or in caliber .223Rem: 65 cm)Medium: .243Win, 6.5x55SE, 6.5mmCreedmoor, .270Win, 7x64, .308Win, .30-06Spring, 8x57JS, 9.3x62Barrel length: 56 cm (optional short barrel length: 51 cm)Magnum: 7mmRemMag, .300WinMag, 8x68SBarrel length: 62 cm (optional short barrel length: 56 cm)
