[0032] An adjustable base rubber (1) for the inventive bullpup rifles, there is a view of the same in FIG. 1 in which it is engaged to the butt (10) and it is one of the main elements of the invention.

[0033] There are two pins (2) on the surface where the base rubber (1) and the butt (10) are connected. Said each pin (2) is engaged with the base rubber (1) with a right angle. The base rubber (1) gains movement feature with the pin (2).

[0034] Another main element of the invention is pin (2), its details can be seen in FIG. 3. There is a node (6) on the pin (2) with cylindrical form which is engaged with the base rubber (1) with a right angle. There are five nodes (6) on the pin (2) included in the Figures. However, the number of nodes (6) can be increased and/or decreased during production.

[0035] Another main element of the invention is the pin housing (9), it can be seen in FIG. 4. Said pin housing (9) is located on the surface where the butt (10) is combined with the base rubber (1). The pin housing (9) is in circular form and its diameter is as big as such that the pin (2) can pass and/or as small as holding said pin (2). Moreover, the depth of the pin housing (9) increases according to the length of the pin (2).

[0036] Another main element of the invention is the lock housing (8), it can be seen in FIG. 4. The lock housing (8) is opened from the side portion of said butt (10) such that it can pass through both pin housings (9) opened on the butt (10) with a right angle. In other words, both pin housings (9) opened on the butt (10) pass through the lock housing (8) opened on the side portion of the butt (10) with a right angle.

[0037] Another main element of the invention is the lock (3), it can be seen in FIG. 5. As well as the lock (3) is in cylindrical form, there is a pin hole (4) thereon through which each pin (2) can pass. The diameter of each pin hole (4) is as big as such that the pin (2) can pass and/or as small as holding said pin (2). Also, there is a notch (5) on the lock (3). The spring (7) which is passed through one end of the lock (3) sits on the notch (5) and/or rests on the same. Therefore, the structure of the spring (7) is in the form to wrap the lock (3) and to rest on the notch (5) and/or sit on the same.

[0038] When we consider the engagement and/or functional relationship of the abovementioned parts with each other; the spring (7) is passed through one end of the lock (3) and/or said lock (3) is passed through said spring (7), thus said spring (7) leans on the notch (5) and/or sits on the same. Then the lock (3) on which the spring (7) is located is seated within the lock housing (8) opened on the butt (10) seen in FIG. 2. When the lock (3) is seated in the lock housing (8), each pin hole (4) which is opened on said lock (3) sits such that they face the pin housing (9), however, the spring (7) prevents the complete alignment of said pin housings (9) and the pin holes (4). However, when a pressure is applied to the portion of the lock (3) outside the butt by the user, the spring (7) is compressed and each pin hole (4) forms a tunnel by aligning with a pin housing (9). The tunnel structure is disrupted and becomes zigzag after the pin holes (4) and the pin housings (9) separate from each other when the pressure applied by the user is ended.

[0039] In order to engage the baser rubber (1) with the butt (10), each pin (2) located on said base rubber (1) is fitted in the pin housing (9) corresponding the same and on the other hand, pressure is applied to the lock (3) and pin holes (4) are enabled to be aligned with said pin housings (9). Therefore, a tunnel through which the pin (2) will pass is formed by means of fully aligning the pin holes (4) and pin housing (9). Afterwards, when the base rubber (1) is engaged with the butt (10) with a desired distance and/or adjustment, the pressure applied to the lock (3) is terminated. The spring (7) pushes said lock (3) and disrupts the alignment of each pin hole (4) when the pressure applied to the lock (3) is stopped. Accordingly, each pin hole (4) leans on the node (6) that is located on the pin (2) and/or it retains said pin (2) from said node (6).

[0040] The use can rest the base rubber (1) completely on the butt (10) but also he/she can be able to make the required adjustment by pulling and/or pushing said base rubber (1) by means of pressing the lock (3), then he/she locks said base rubber (1) to said butt (10) by means of terminating the pressure applied on said lock (3).
