In such an arrangement, the frame may include first and second longitudinal sides and front and rear sides, wherein the rear side includes a laterally open recess, and wherein the frame is laterally deferrable on a muzzle flash eliminator of an automatic firearm. The nozzle body may include a male thread on the outer periphery of the nozzle body and may be adapted to be screwed into the threaded bush and to extend into the muzzle flash eliminator. In one example, the nozzle body includes a longitudinal tapped blind hole extending a length within the nozzle body and a spray hole extending from a muzzle at an outer surface of the nozzle body to the longitudinal tapped blind hole and the longitudinal tapped blind hole includes an elongated portion extending beyond the spray hole and having a volume of at least one bullet discharged from the automatic firearm. The cover bushing is connected with the threaded bush, wherein the cover bushing is located over the nozzle body when the nozzle body is screwed into the threaded bush.
