In an automatic rifle which has been converted for non-military purposes to be semi-automatic by the removal of parts that allow its automatic function, additional suppressing elements are provided to ensure that the interrupter remains depressed until the bolt carrier fully passes the striker catch before the striker catch is engaged by the interrupter. This prevents premature connection of the striker catch and the interrupter, which could prevent sufficient striker spring pressure so that the next round can be fired. In one embodiment the trigger mechanism is fitted with an additional suppressing element (10) formed as a side push plate 7 on the bridge (6) of bolt carrier (5). In a second embodiment the interrupter is provided with a pin (8) protruding to the left, in a direction of fire, while the receiver side wall has a cavity (11), over which a thin metal sheet (9) with a beveled corner is placed such that between the lower edge of metal sheet (9) and the lower edge of cavity (11), as well as between rear edge of metal sheet (9) and rear edge of cavity (11) a gap (12) is provided to receive the pin. The additional suppressing element is particularly applicable to a Czech model SA vz .58 semi-automatic rifle which has been converted for non-military purposes.
In an automatic rifle which has been modified for non-military purposes by removing one of two striker catches, a release lever and one arm of a trigger mechanism feather, leaving a trigger connected to an interrupter which moves forwardly in a direction of fire and vertically, and in its rear upward position engages a striker catch, a bolt carrier including a lower downwardly extending bridge, which during its rearward movement within the receiver of the rifle is adapted to engage and depress the interrupter, the improvement comprising:
A semi-automatic rifle comprising:
A bolt carrier for a firearm, the bolt carrier extending longitudinally in the fire direction and including a downwardly extending bridge on its rear lower surface, and
A firearm having a receiver and an interrupter within the receiver, the interrupter being actuated for forward movement by a trigger and and capable of upward movement to cooperate with a striker catch;
A method of converting an automatic rifle which has been modified for non-military purposes by removing one of two striker catches, a release lever and one arm of a trigger mechanism feather, leaving a trigger connected to an interrupter which moves forwardly in the direction of fire and vertically, and in its rear upward position engages a striker catch, a bolt carrier including a lower downwardly extending bridge, which during its rearward movement within the receiver of the rifle may engage and depress the interrupter, and wherein the conversion includes;
