Small and medium calibre hand firearm - has pivoting breech block dropping under gravity and locked by lever-operated sliding wedge

摘要

The hand firearm is for small-and medium-calibre ammunition, and includes a breech block. The block (12) drops under gravity, pivoting at a point (13) above the axis of the barrel (10), and is locked in place by a wedge (14), sliding in the lenghtwise direction of the firearm under the action of a pivoting release lever (15). The pivoting release lever can have an actuating lug (16) and the wedge can have a protrusion engaging under the block. The fore- and back-sights can be tilted about the lengthwise axis of the firearm by a micrometer screw.
