As with the S 404, the S 303’s ergonomically perfect and smooth metal cocking slide on the bolt shroud also allows the rifle to be cocked both comfortably and extremely silent. By pressing the button with the thumb, the cocking slide silently slides back into the uncocked position. In addition it is also possible to load and unload the rifle in the uncocked position: To do so, simply tap the cocking slide and safely open the S 303.

The SUM is available for all common mounting rails as well as for all ring diameters from 1 inch to 40 mm.
