wherein the stock assembly (C) further comprises a folding mechanism with a lock (C1) that allows folding the stock and a retractable telescopic button mechanism (C2) that allows graduation to users of different heights;
wherein the folding mechanism with lock (C1) comprises:
a base adapter stock (19) that is attached to a rear of the assault rifle and allows the stock to be folded up either to the right or to the left;
a stock bolt (18) that secures the stock base adapter (19) to the weapon;
a cylinder head base block (20) attached to the cylinder head base adapter (19) by a screw (21) that rotates at angles of up to 180°;
a joint block (25), which houses a cylinder head base shaft (22) that allows the locking mechanism of the cylinder head to be released and deployed, the joint block (25) includes a slot where a cylinder head guide (28) and a guide core (52) are housed, the cylinder head guide (28) and the guide core (52) are permanently attached to each other and made of different materials;
wherein the cylinder head base shaft (22) is cylindrical with section changes;
wherein the section change secures the shaft (22) by the cylinder head fixing ring (51), which prevents the shaft from being expelled by a cylinder head base spring (23) and allows the shaft (22) to return to an original position; and
wherein the cylinder head base shaft (22) allows the vertical movement of the union block (25) provided by the cylinder head base spring (23).
