About the Sauer S404 Synchro XTC

The Sauer S404 Synchro XTC is an ultra-lightweight German precision rifle featuring a carbon fiber-reinforced polymer stock and the renowned Sauer Quattro adjustable trigger. Weighing just 2.7 kg empty, it is one of the lightest modular bolt-action precision platforms available, making it exceptionally well-suited for mountain hunting and mobile tactical applications. The S404 platform features the SUS (Sauer Universal Key) system for rapid barrel and stock changes, allowing caliber conversion in minutes. Cold hammer forged barrels are guaranteed to deliver sub-MOA accuracy, and the adjustable comb provides a consistent cheek weld for precision optics use.

J.P. Sauer & Sohn is one of the oldest firearms manufacturers in the world, founded in 1751 in Suhl, Germany. The S404 Synchro XTC represents the pinnacle of their engineering philosophy -- achieving maximum precision with minimum weight. The carbon fiber stock technology borrowed from the aerospace industry helps achieve a rifle weight that seems almost impossibly light for its capability.
