ABSTRACT:
An airgun comprising a valve intended to be in contact with a compressed air cartridge, a barrel, into which a bullet is insertable, and a passageway connecting the valve with the barrel. Moreover, the airgun has element with a plurality of through holes of different diameters, which element is arranged in the passageway so that a part of the element comprising at least one of said holes extends transversely of the passageway. The diameter of the hole or holes which is/are positioned in the passageway thus defines the effective cross-section of the passageway and, consequently, the flow through the passageway. This means that the invention offers a better possibility of controlling the air flow.
