S 404 Silence XTC
Sauer 303 / Sauer 404 Universal Mount
The S 404’s and 303's specially designed Sauer Universal Mount (SUM) combines an extremely low and elegant profile with absolute shooting stability and return to zero. This ensures that the shooter can focus on the target at lightning-fast speed and does not need to lift his head in order to use the full potential of accuracy. The SUM is available for all common mounting rails as well as for all ring diameters from 1 inch to 40 mm.
