Sour exchange barrel 505/404 Heavy fluted

Cannelured 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 canneluring of the S404 exchange barrel significantly increases the barrel surface area. This allows the barrel to dissipate the heat generated during high shot sequences much more effectively. This prevents the annoying mirage over the barrel. The elegant aesthetics of the cannelured barrel is convincing, as it visually integrates well into the overall appearance of the noble Sauer hunting rifles.
Sauer also offers a wide selection of calibers for the S404 even with the heavy barrels, depending on the caliber group, up to three barrel lengths with and without sights and M 17x1 threads are available.
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, there remains a soft steel core. 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.
