Abstract

The application relates to a blank firing adaptor (100) for a firearm according to an embodiment, which comprises a body (102) for stopping a projectile and a booster (214) for restricting an outflow of propellant gas (R). The body and the booster (102, 214) comprise flow openings (110, 222) for the outflow of propellant gas. The booster is configured to be attached against the body so that a projectile channel (320) of the booster is aligned with a barrel of the firearm when the blank firing adaptor is attached to the firearm. The booster further comprises an attachment member (128) configured to attach the blank firing adaptor to an end of the barrel of the firearm so that the booster is positioned between the attachment member and the body when the blank firing adaptor is assembled.

Abstract

A firearm suppressor with a simple, light, easy-to-manufacture and easy-to clean is provided. In the device and solution provided, the propellant gas is not stopped inside the suppressor but directed to flow in a controlled manner through the suppressor and out of the suppressor. This significantly reduces the heating of the suppressor, the fouling of the firearm by propellant gases and gunpowder firing residues. Moreover, the solution reduces contact of the propellant gases with the shooter's face.

Abstract

The application relates to a firearm suppressor (102) according to an embodiment, having a first end (106) comprising a bullet entry opening (108), an outer casing (104), a baffle element (224) comprising a bullet passageway (226), a bullet channel (328) for a the propagation of a bullet, expansion chambers (320, 322) for a cooling of gas, a second end (114) comprising a bullet exit opening (116) and at least one gas exhaust opening (118). The suppressor is adapted to direct a propellant gas discharged from the firearm out of the suppressor through at least one gas exhaust opening at at least the second end. The first end, the outer casing, and the second end define the expansion chambers so that a first expansion chamber (320) is formed between the first end and the baffle element, and the bullet channel and a second expansion chamber (322) are formed between the baffle element and the second end. The baffle element is adapted to direct a portion of the propellant gas discharged from the firearm in the second expansion chamber onto an inner surface (342) of the outer casing to cool it so that the cooled propellant gas can flow out of the suppressor via at least one exhaust opening and a bullet channel in connection with the exit opening.
