Magazine with a plurality of cylinders in series, in particular for compressed-air guns

A shot magazine for repeating guns, especially compressed-air guns, in which shots are housed in respective chambers provided in the magazine around an axis of rotation of same, and in which the gun comprises:

• a trigger;
• a mechanism for rotating the magazine around its own axis, which can be controlled by said trigger for placing a chamber housing a shot in correspondence with a barrel of the gun;
• and
• a firing mechanism, which can likewise be controlled by said trigger for acting on a valve for controlling a flow of a firing gas coming from a source of pneumatic energy and to induce firing of the shot, which is aligned with said barrel of the gun, wherein it comprises at least two cylinders in series, front and rear, respectively, said front cylinder being provided with N identical chambers for housing the shots and with a crown of N teeth intended to be engaged by said mechanism of rotation, said rear cylinder being provided with N−1 chambers for housing shots and with an aperture of smaller diameter than said chambers for housing shots, for passage of said firing gas from said valve to a said chamber of said front cylinder, from time to time aligned with the barrel, and complementary coupling means, which are shaped to interact with one another for a contemporary rotation of two cylinders only after the first N shots have been fired by said front cylinder.
