FIELD: military equipment, in particular, anti-infantry subbarrel grenade launchers. ^ SUBSTANCE: the retainer of the shot retaining mechanism is made in the form of a single-arm lever with a retaining member made on the end of the lever arm and installed in the hole of the barrel wall with a structural clearance for engagement with the shot. The retainer pin is so positioned that the force of extraction exceeds the feed force. Besides, the retainer pin is positioned between the hole in the barrel wall and the barrel muzzle part on s straight line passing through the point of intersection of the normals to the surfaces of feeding and extraction, having slopes and respectively, at angle to the horizon expressed by a mathematical dependence. ^ EFFECT: provided safety of use and enhanced efficiency of the shot retaining mechanism. ^ 2 cl, 4 dwg |
