A toy-arm imitating a portable fire-arm, operating by compressed air for the pneumatic launch of a light bullet, made up of two reciprocally movable carriers, one first of which comprises a cylinder lined up and communicating with the barrel and a reaction bearing for a spring acting on a piston to urge it into such a direction as to compress the air in the cylinder for the pneumatic launch of the bullet; the second carrier comprises an elastic tooth which hooks up the piston to drag it along while loading the spring, and the first carrier has a profile capable of gradually acting on the elastic tooth at the end of the relative stroke between the two carriers, until causing the release of the piston and its trip thanks to the loaded spring.
