Claim 9:
10. The assault rifle conversion kit as in claim 9, wherein said folding mechanism with lock (C1) comprises a butt base button (26) having a prominent projection and a no prominent projection, the prominent projection includes a knurling to operate without slipping and the no prominent projection generates geometric interference between the cylinder head base block (20) and the butt base button (26) due to the pivoting of the union block (25) and is kept in said position by the spring cylinder head button (31); an elastic coil pin (24) that prevents the butt base button (26) from being ejected and fixed to the union block (25); wherein the pressure of the butt base button (26) compresses the button spring button head (31), releases the union block (25) of said interference and permits and brings down the cylinder head.
