[0018] Numbers are placed on the pictures in order to better understand the combination of plastic receiver and carrier tube fixed by means of the fixing nut subject to the invention. Accordingly; [0019] 1. Carrier tube [0020] 2. Fixing nut [0021] 3. Resistance bush [0022] 4. Sling holder [0023] 5. Sling holder fixing nut [0024] 6. Thread [0025] 7. Plastic receiver [0026] 8. Mounting channel [0027] 9. Nut groove

[0028] As shown in FIG. 1, the subject of the invention, the carrier tube (1) is fixed to the plastic receiver (7) by means of the fixing nut (2). The fixing nut (2) allows the plastic receiver (7) and the carrier tube (1) to be detached from each other when required. The carrier tube (1) shown in FIG. 5 is produced from an aluminum and/or aluminum-derived material. There are threads (6) on at least one end of the carrier tube (1) shown in FIG. 5. Sling holder fixing nut (5) and sling holder (4) are positioned on the carrier tube (1), respectively.

[0029] During the production, firstly the sling holder fixing nut (5) is fully tightened to the threads (7) that are at one end of the carrier tube (1). Then the sling holder (4) is mounted. The sling holder (4) is tightened until it rests on the sling holder fixing nut (5). Then, the resistance bush (3) is passed through the carrier tube (1). However, the inner surface of the resistance bush (3) is smooth; that is, it cannot be fixed on the threads (7) since it is not grooved. The resistance bush (3) is produced from a metal and/or metal-derived material.

[0030] The plastic receiver (7) shown in FIG. 4 is produced by pressing plastic into a mold via injection or casting method. During production, the threads (6) of the carrier tube (7) are passed through the mounting channel (8) formed on the plastic receiver (7). The inner surface of the mounting channel (8) formed in the plastic receiver (7) is smooth; that is, it has a smooth structure. The resistance bush (3) on the threads (6) of the carrier tube (1) connected to the mounting channel (8) contacts with the mounting channel (8). This way, the resistance bush (3) increases the strength of the plastic receiver (7) it is in contact with. However, since the resistance bush (3) cannot be fixed to the threads (6), it cannot fix the plastic receiver (7) to the carrier tube (1).

[0031] In order to fix the carrier tube (1) to the plastic receiver (7), it is tightened by turning the fixing nut (2) on the carrier tube (1) and from the part of the carrier tube (1) which is inside the plastic receiver (7). The fixing nut (2) is positioned in the nut groove (9) that is inside the mounting channel (8). It is possible to form the nut groove (9) during the production of the plastic receiver (7). The nut groove (9) can optionally be formed after the plastic receiver (7) is produced.

[0032] The fixing nut (2) shown in FIG. 2 is optionally produced from metal and/or metal-derived material. The fixing nut (2) is fastened and mounted on the threads (6) by means of the grooved structure on its inner surface. In addition, a part of the upper surface of the fixing nut (2) is produced in rough form. The surface area of the fixing nut (2) increases thanks to its rough surface. Thus, the traction of the fixing nut (2) in the nut groove (9) increases. The grooved structure of the inner surface and the rough structure of the outer surface of the fixing nut (2) shown in FIG. 3 ensure the fixation of the plastic receiver (7) and the carrier tube (1). Depending on the use of the rifle, the fixing nut (2) can be disassembled as a result of the carrier tube (1) coming out of the plastic receiver (7) automatically. The technical problem is solved by replacing the removed fixing nut (2) with a new fixing nut (2).

[0033] After fixing the carrier tube (1) and the plastic receiver (7), at least two threads (6) remain free between the plastic receiver (7) and the sling holder (4). Then the sling holder fixing nut (5) is turned towards the plastic receiver (7). Thus, the sling holder (4) moves towards the plastic receiver (7). This motion continues until the sling holder (4) rests to the plastic receiver (7). There are no free threads (6) left between the plastic receiver (7) and the sling holder (4) which abut each other by means of the sling holder fixing nut (5).

[0034] The recoil spring is positioned on the inner surface of the carrier tube (1). This way, it becomes possible to attach different types of stocks on the same carrier tube (1).
