DETAILED DESCRIPTION OF THE INVENTION

[0034] In this detailed description, preferred embodiments of the dual system bullpup rifle of the present invention are described so as to provide a better understanding of the subject and have no limiting effect.

[0035] The dual system bullpup rifle (A) according to the invention is related to the gas system (5), which can be used in all tactical magazine-fed weapons, especially of the bullpup type, known in the art as pump-action, semi-automatic and automatic, and allow the weapon to be used in pump-action and/or semi-automatic system according to demand. Said gas system (5) is directly connected to the barrel (3) (FIG. 2).

[0036] In the dual system bullpup rifle (A) according to the invention, the embodiments of the invention are located on the front body (1). The ammunition/cartridge is fired in the barrel (3), wherein there is a barrel housing (4) located on the barrel (3) in order to be affected by the heat resulting from firing and for the grip ergonomics of the rifle. On said barrel housing (4), there is a latch guide (4.1) formed for connecting the selection latch (5.1) to the gas chamber (5.3). In the lower part of the barrel (3), there is a hand stock (2), which is connected to the mechanism by means of a lever and sets the rifle by fore-back movement by the user in the pump-action/manual use of the rifle. There is a stock lock (2.1) on the said hand stock (2), which locks and releases the hand stock (2) by the user (FIG. 1).

[0037] The gas system (5) according to the invention contains basically four main parts. Among these, there is the gas chamber (5.3), which has a gas passage into it from the gas generated within the barrel (3) through the opening-closing of the gas discharge holes (3.1) on the barrel (3) according to the system (semi-automatic or pump-action) on which the rifle (A) will operate. A lock nut (5.2), which enables the firm connection to the barrel (3), is located on one side of the gas chamber (5.3), and a piston (5.4), which transmits the gas contained in it into the gas chamber (5.3) when the rifle operates on semi-automatic system and allows the rifle to be set again, on the other side. The gas passage to the gas chamber (5.3) is provided by at least one gas discharge hole (3.1) formed on the barrel (3). Opening-closing the gas discharge hole (3.1) by rotating said gas chamber (5.3) clockwise and/or counterclockwise over the barrel (3) by means of the selection latch (5.1) connected to a latch slot (5.1.1) formed on the gas chamber (5.3) provides the rifle to be operated in pump-action or semi-automatic system.

[0038] Operation in the semi-automatic system: Firstly, hand stock (2) is locked to prevent it from moving by pressing the stock lock (2.1) located on it. By turning the gas chamber (5.3) over the barrel by means of the selection latch (5.1), a gas passage is provided through the discharge hole (3.1). Shooting is done; after each shot, piston (5.4) mechanism is set again with the gas coming into the gas chamber (5.3).

[0039] Operation in the pump-action system: Firstly, hand stock (2) is unlocked to enable it to move by pressing the stock lock (2.1) located on it . By turning the gas chamber (5.3) over the barrel by means of the selection latch (5.1), the discharge hole (3.1) is closed and the gas passage to the gas chamber (5.3) is prevented. Shooting is done; after each shot, mechanism is set again by pulling the hand stock (2) back (to the trigger) and releasing it.
