A carbine, essentially characterized by the arrangement of the barrel inside an envelope tube with axial sliding ability thereof, guided by a stop in a longitudinal groove of said wrapping tube preventing rotation on its axis of said barrel, which is susceptible to drive a plunger on its back that slides inside said tube and that receives the action of a powerful rear helical spring, overcoming to which said piston is retained in the back of the enclosing tube, with the possibility of compressing the gas that at atmospheric pressure is contained in the chamber between said piston and the rear part of the barrel, producing an increase in pressure capable of projecting the pellet along the barrel at the moment when the trigger is pressed.
