The Sauer 404 Synchro XT Heavy Barrel Rifle delivers ultimate ergonomics, shooting comfort, and match-grade precision by pairing a 20-inch cold hammer-forged heavy barrel with an ultra-rugged polymer thumbhole stock. Chambered in the globally trusted .30-06 Springfield caliber, the expanded 19mm heavy contour slows barrel heating and dampens parasitic harmonics to maintain exceptional sub-MOA uniformity over extended strings of fire. The nearly indestructible, weather-resistant stock features a premium Soft Touch coating, non-slip elastomeric grip panels, and an infinitely adjustable comb that can be perfectly tailored to your posture using the forearm-housed Sauer Universal Key (SUS) tool. Engineered with an integrated six-lug breech recess that locks the bolt directly into the barrel framework, this foundational assembly features the J.P. Sauer & Sohn proprietary Sauer Universal Mount (SUM) interface and an adjustable four-stage DX2 trigger module, allowing marksmen to swap calibers seamlessly while maintaining a guaranteed return-to-zero.
