The Sauer 80117170 505 barrel in .300 Winchester Magnum is a factory replacement barrel engineered for shooters who want to extend the life of their Sauer 505 rifle or swap to a fresh tube without the gunsmith work. Built to Sauer's exacting standards, this barrel arrives with a 9/16" x 24 thread pattern, ready to drop into your existing action. Whether you're a long-range hunter pushing the limits of .300 Win Mag ballistics or a precision shooter ready to start fresh after heavy use, a quality factory barrel is the straightforward path to accuracy and reliability.
The .300 Winchester Magnum is proven medicine for big-game hunting and extended-range shooting across North America. This barrel maintains the chamber and thread specifications that make it a true Sauer part—no guesswork, no fitment surprises. If you're rebuilding a rifle, transitioning between caliber preferences, or simply want factory-fresh performance, having an OEM barrel on hand means you can make that change without delays or compatibility headaches.
Sauer's reputation in precision rifle manufacturing carries through to their replacement barrels. This is genuine factory hardware, not an aftermarket approximation. Pair it with a competent gunsmith for installation, or keep it as a backup should you ever need to return your rifle to service. For Sauer 505 owners, it's peace of mind in steel.
