Abstract

The invention relates to a hand-held firearm comprising a muzzle silencer (9) and a barrel (11) which is provided with transverse bores and is surrounded by an expansion area (15) into which the transverse bores extend. The transverse bores (14) enable the muzzle velocity of the bullets to be less than Mach 1, in spite of the use of conventional ammunition, and there is consequently no supersonic boom of the bullet. To selectively eliminate the reduction in firing energy involved therein and be able to shoot with maximum firing force, the transverse bores (14) are selectively closable by a locking device (16) which is preferably in the form of a sleeve (16) which surrounds the barrel (11) and is mounted for rotation thereon and is furthermore provided with an actuating member (21) for setting the open or closed position. The actuating member may take the form of a tube section (21) surrounding the barrel (11) in spaced relationship thereto at least over part of its length and delimiting the expansion area (15), with its both ends connected with the barrel in sealed relationship and mounted on the barrel (11) for rotation. The tube section is connected with the sleeve (16) for rotation therewith (FIG. 2).

Description

Die Erfindung betrifft eine Handfeuerwaffe mit einem Mündungsschalldämpfer und einem quer durchbohrten Lauf, mit einer Verschliessvorrichtung zum wahlweisen Verschliessen des Weges von der Querbohrung nach aussen, wobei die Verschliessvorrichtung eine den Lauf umgebende und auf ihm drehbar gelagerte Hülse ist, die mit einem Betätigungsorgan zum Einstellen der Offenstellung bzw. der Schliessstellung versehen ist, wobei die Hülse einen mit der Querbohrung zur Deckung bringbaren Kanal aufweist.The invention relates to a handgun with a muffler and a cross-drilled barrel, with a locking device for optionally closing the path from the cross hole to the outside, the locking device being a sleeve surrounding the barrel and rotatably mounted on it, with an actuator for adjusting the The open position or the closed position is provided, the sleeve having a channel which can be brought into congruence with the transverse bore.

Bei einer derartigen aus der DE-A-2 542 758 bekannten Waffe ist eine Hülse vorgesehen, die infolge ihrer in Längsrichtung an der Innenseite eingearbeiteten Kanäle wahlweise mit voller Energie zu schiessen gestattet, oder mit verringerter Energie, weil ein Teil der Verbrennungsgase das Geschoss überholen kann. Die Hülse lässt sich bei der bekannten Waffe nicht ohne Entfernen des Laufs von der Waffe abnehmen, wie dies beispielsweise zur Reparatur erforderlich sein kann.In such a weapon known from DE-A-2 542 758, a sleeve is provided which, as a result of its channels incorporated in the longitudinal direction on the inside, allows it to be fired either at full energy or with reduced energy because part of the combustion gases overtake the projectile can. In the known weapon, the sleeve cannot be removed from the weapon without removing the barrel, as may be necessary for repair, for example.

Durch die US-A-2 451 514 ist eine den Schussknall vermindernde Mündungsbremse für Gewehre bekannt, die wahlweise eingeschaltet oder ausgeschaltet werden kann. Der Lauf weist hierzu Bohrungen auf, und auf dem Lauf ist eine Aussparungen aufweisende, vom Lauf abnehmbare Hülse drehbar montiert. Je nach Drehstellung der Hülse können Verbrennungsgase aus dem Lauf durch die Aussparungen der Hülse hindurch entweichen oder nicht. Bei abgenommener Hülse sind die den Lauf durchsetzenden Bohrungen offen.US-A-2 451 514 discloses a muzzle brake for rifles which reduces the shot bang and can be switched on or off as desired. For this purpose, the barrel has bores, and a sleeve which has cutouts and can be removed from the barrel is rotatably mounted on the barrel. Depending on the rotational position of the sleeve, combustion gases may or may not escape from the barrel through the recesses in the sleeve. When the sleeve is removed, the holes passing through the barrel are open.

Der Erfindung liegt die Aufgabe zugrunde, eine Handfeuerwaffe der eingangs geschilderten Art so auszubilden, dass ein Expansionsraum mit gegenüber dem Volumen der Kanäle in der Hülse der bekannten Waffe grösserem Volumen vorgesehen werden kann, und bei dem der Mündungsschalldämpfer und der den Expansionsraum aussen begrenzende Teil der Schalldämpfvorrichtung leicht abgenommen werden können, ohne dass der Lauf entfernt werden muss. Da die Waffe in diesem Fall bei abgenommenem Schalldämpfer noch schussbereit ist, soll eine Gefährdung für den Schützen durch seitlich aus dem Lauf austretende Verbrennungsgase vermieden werden.The invention has for its object to design a handgun of the type described in such a way that an expansion space with a larger volume than the volume of the channels in the sleeve of the known weapon can be provided, and in which the muffler and the part of the expansion space delimiting the outside Muffler can be easily removed without having to remove the barrel. Since the weapon is still ready to fire in this case when the silencer is removed, a hazard to the shooter from combustion gases escaping from the side of the barrel should be avoided.

Diese Aufgabe wird dadurch gelöst, dass ein Expansionsraum vorgesehen ist, der durch einen den Lauf mindestens über einen Teil seiner Länge mit Abstand umgebenden, als Betätigungsorgan für die Hülse dienenden Rohrabschnitt begrenzt ist, dessen beide Enden mit dem Lauf abgedichtet verbunden sind, dass der Rohrabschnitt drehbar auf dem Lauf gelagert und mit der Hülse über eine formschlüssige Kupplung drehstarr verbunden ist, die durch axiales Verschieben ausser Eingriff bringbar ist, dass der Rohrabschnitt zusammen mit dem vor der Laufmündung anschliessenden Mündungsschalldämpfer aufsteckbar ist, dass der Rohrabschnitt und der Mündungsschalldämpfer mit einem gemeinsamen Anschlussstück versehen sind, das in Art eines Renkverschlusses mit dem Lauf im Bereich der Laufmündung verbindbar ist, und dass die Anordnung derart getroffen ist, dass beim Drehen des Rohrabschnitts in diejenige Stellung, in der der Mündungsschalldämpfer zusammen mit dem Rohrabschnitt axial vom Lauf abgezogen werden kann, die Querbohrung durch die Hülse abgedeckt ist und nicht in Verbindung mit dem Kanal steht. Ein Renkverschluss stellt eine Verbindung durch eine Kombination einer Schiebe- mit einer Drehbewegung her. Renkverbindungen sind als Bajonettverschlüsse in der Technik bekannte Bauelemente.This object is achieved in that an expansion space is provided which is delimited by a pipe section which surrounds the barrel at least over part of its length and serves as an actuating element for the sleeve, the two ends of which are connected to the barrel in a sealed manner such that the pipe section is rotatably mounted on the barrel and is connected in a torsionally rigid manner to the sleeve via a form-fitting coupling, which can be disengaged by axial displacement, that the pipe section can be plugged together with the muffler connecting before the barrel muzzle, and that the pipe section and the muffler with a common connecting piece are provided, which can be connected in the manner of a bayonet lock to the barrel in the area of the barrel muzzle, and that the arrangement is such that when the tube section is turned into the position in which the muffler can be axially removed from the barrel together with the tube section n, the cross hole is covered by the sleeve and is not connected to the channel. A bayonet lock creates a connection by a combination of a sliding and a rotating movement. Bayonet connectors are components known in the art as bayonet catches.

Vorteile der Erfindung liegen in der einfachen Konstruktion, denn es muss nicht unbedingt eine Verbindung vom Expansionsraum zum Mündungsschalldämpfer bestehen. Auch weist der Expansionsraum ein ausreichendes Volumen auf und wirkt an der Waffe nicht störend. Die Waffe, bei der die Schalldämpfvorrichtung eingeschaltet oder ausgeschaltet werden kann, kann somit wahlweise mit voller Geschossenergie oder mit reduzierter Geschossenergie arbeiten. Wenn der Mündungsschalldämpfer zusammen mit dem Rohrabschnitt ohne Demontieren des Laufs von der Waffe abgenommen wird, was wegen des Renkverschlusses einfach möglich ist, so ist die Waffe noch schussbereit, eine Gefährdung des Schützen wird aber deshalb vermieden, weil das Abnehmen des Mündungsschalldämpfers und des Rohrabschnitts nur in derjenigen Drehstellung der Hülse möglich ist, in der die Hülse die Querbohrung des Laufs verschliesst, so dass keine Verbrennungsgase aus dem Lauf seitlich austreten können. Die Kupplung besteht aus einem Aussenzahnkranz der Hülse und einem dazu passenden Innenzahnkranz des Rohrabschnitts. Eine derartige Kupplung überträgt die auftretenden Kräfte zuverlässig und ist leicht zerlegbar und wieder zusammensteckbar. Die Tatsache, dass der Rohrabschnitt zusammen mit dem vor der Laufmündung anschliessenden Mündungsschalldämpfer abnehmbar ist, der Rohrabschnitt also mit dem Mündungsdämpfer zu einer Einheit zusammenmontiert ist, hat handhabungstechnische Vorteile, weil der Mündungsschalldämpfer, der Rohrabschnitt und die Hülse ohnehin überwiegend gemeinsam verwendet werden. Von Vorteil ist, dass einerseits wegen des ausreichenden Durchmessers des Rohrabschnittes eine ausreichende Verstellkraft auf die Hülse aufgebracht werden kann und dass andererseits für die Betätigung der Hülse keine vorstehenden und möglicherweise zu Störungen oder Behinderungen Anlass gebenden Hebel oder Armaturen erforderlich sind.Advantages of the invention lie in the simple construction, since there is not necessarily a connection from the expansion space to the muffler. The expansion space also has a sufficient volume and does not interfere with the weapon. The weapon with which the silencing device can be switched on or off can thus either work with full projectile energy or with reduced projectile energy. If the muzzle silencer is removed from the weapon together with the pipe section without disassembling the barrel, which is simply possible because of the bayonet lock, the weapon is still ready to fire, but a danger to the shooter is avoided because the muzzle silencer and the pipe section are only removed is possible in the rotational position of the sleeve in which the sleeve closes the transverse bore of the barrel, so that no combustion gases can escape laterally from the barrel. The coupling consists of an outer ring gear of the sleeve and a matching inner ring gear of the pipe section. Such a coupling reliably transmits the occurring forces and is easy to dismantle and put back together. The fact that the pipe section together with the muffler connected in front of the barrel muzzle can be removed, i.e. the pipe section with the muffler is assembled into one unit, has technical handling advantages because the muffler, the pipe section and the sleeve are mostly used together anyway. It is advantageous that, on the one hand, because of the sufficient diameter of the pipe section, a sufficient adjusting force can be applied to the sleeve and, on the other hand, that no protruding levers or fittings, possibly giving rise to faults or disabilities, are required for the actuation of the sleeve.

Die erfindungsgemässe Waffe eignet sich für Spezialeinsätze, beispielsweise bei Kommandounternehmen, bei denen in manchen Fällen schallgedämpft und mit verminderter Geschossenergie geschossen werden muss, in anderen Fällen jedoch die volle Geschossenergie der Munition zur Verfügung stehen soll.The weapon according to the invention is suitable for special missions, for example in command companies, in which in some cases soundproofing and firing with reduced projectile energy is required, but in other cases the full projectile energy of the ammunition is to be available.

Bei einer Ausführungsform der Erfindung, bei der die Hülse an ihrer Innenoberfläche mit eingearbeiteten Längskanälen versehen ist, deren eines Ende bis in den Bereich der in den Lauf eingearbeiteten Querbohrungen reicht, ist vorgesehen, dass die Längskanäle am anderen Ende der Hülse in die Hülsenwand durchdringende Querbohrungen münden. Die Querbohrungen bilden also zusammen mit den Längskanälen ein Verbindungssystem, das vom Lauf über dessen Querbohrungen zum Expansionsraum führt.In one embodiment of the invention, in which the sleeve is provided on its inner surface with incorporated longitudinal channels, the egg nes end extends into the area of the transverse bores machined into the barrel, it is provided that the longitudinal channels open at the other end of the sleeve into the sleeve wall penetrating transverse bores. The cross bores, together with the longitudinal channels, form a connection system that leads from the barrel through its cross bores to the expansion space.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in vereinfachter und schematisierter Darstellung gezeigt, das anschliessend erläutertwird. Es zeigen in vereinfachter und schematisierter Darstellung unter Weglassung für das Verständnis der Erfindung nicht erforderlicher Einzelheiten:

  • Fig. 2 einen Teil-Längsschnitt durch den Lauf und die angrenzenden, der Schalldämpfung dienenden Teile der Waffe nach Fig. 1,
  • Fig. 3, 4 und 5 Querschnitte entsprechend den Linien 111-111, IV-IV und V-V in Fig. 2.
In the drawing, an embodiment of the invention is shown in a simplified and schematic representation, which is subsequently explained. In a simplified and schematic representation, omitting details that are not necessary for understanding the invention:
  • 1 is a weapon with attached muffler,
  • 2 shows a partial longitudinal section through the barrel and the adjacent parts of the weapon according to FIG.
  • 3, 4 and 5 cross sections corresponding to lines 111-111, IV-IV and VV in Fig. 2nd

Die in Fig. 1 dargestellte Maschinenpistole umfasst ein Gehäuse 1 mit einem den Lauf abdeckenden Handschutz 10, einer Visierung 2 und einer Ladevorrichtung 3. Die Waffe umfasst ferner einen Pistolengriff 4 mit einem Abzugskasten 5 und einem Abzug 6, sowie eine Schulterstütze 7, ein Stangenmagazin 8 und einen Mündungsschalldämpfer 9, der an die Laufmündung angesetzt ist. Die Waffe gemäss der Darstellung von Fig. 1 ist bekannt (MP 5 SD 3 der Firma Heckler & Koch GmbH).The submachine gun shown in FIG. 1 comprises a housing 1 with a handguard 10 covering the barrel, a sight 2 and a loading device 3. The weapon also comprises a pistol grip 4 with a trigger box 5 and a trigger 6, as well as a shoulder rest 7, a rod magazine 8 and a muzzle muffler 9 which is attached to the barrel muzzle. The weapon according to the illustration in FIG. 1 is known (MP 5 SD 3 from Heckler & Koch GmbH).

Gemäss Fig. 2 ist ein Lauf 11, der an seinem rückwärtigen Ende ein Patronenlager 12 aufweist, durch einen in der Zeichnung nur angedeuteten Verschluss 13 abgeschlossen. In den Lauf sind im geringen Abstand vor dem Patronenlager 12 die Laufwandung durchdringende Querbohrungen 14 eingearbeitet. Durch diese Querbohrungen 14 dringt nach dem Abschuss Treibgas in einen Expansionsraum 15, wodurch die dem Geschoss erteilte Energie auch bei Verwendung üblicher Munition so stark reduziert wird, dass die Mündungsgeschwindigkeit des Geschosses unter der Schallgeschwindigkeit liegt, wodurch der Geschossknall (Überschall-Knall) vermieden wird.According to FIG. 2, a barrel 11, which has a cartridge chamber 12 at its rear end, is closed by a breech 13, which is only indicated in the drawing. Cross bores 14 penetrating the barrel wall are machined into the barrel at a short distance in front of the cartridge chamber 12. Through these cross bores 14, propellant gas penetrates into an expansion space 15 after the shot, whereby the energy imparted to the projectile is reduced so much, even when using conventional ammunition, that the muzzle velocity of the projectile is below the speed of sound, thereby avoiding the bullet bang (supersonic bang) .

Um diese Verbindung nach Belieben auch unterbrechen zu können, wodurch ein Schuss mit voller Geschossenergie abgefeuert werden kann, ist eine Hülse 16 auf dem Lauf 11 begrenzt drehbar gelagert, wobei sie axial durch einen Querstift 17 fixiert ist, der in eine Aussenumfangsringnut 18 eingreift. In die Hülse 16 sind drei Längskanäle 19 gleichmässig um den Umfang verteilt in die Innenoberfläche eingearbeitet, die an ihrem der Laufmündung zugewandten Ende in je eine Querbohrung 20 übergehen, die die Hülsenwandung durchsetzt und die in den Expansionsraum 15 mündet. Bei entsprechender Winkellage der Hülse 16 zum Lauf 11 überdecken die Kanäle 19 mit ihrem dem Verschluss 13 benachbarten Ende je eine der Querbohrungen 14. Wird dagegen die Hülse 16 aus dieser Stellung um beispielsweise 30° verschwenkt, wie dies in Fig. 4 dargestellt ist, dann sind die Längskanäle 19 tangential zu den Querbohrungen 14 versetzt und diese dadurch verschlossen. Um eine Abdichtung zwischen Hülse und Lauf zu erzielen, können die einander gegenüberliegenden Flächen in Art einer Labyrinthdichtung gestaltet sein.In order to be able to interrupt this connection at will, as a result of which a shot can be fired with full projectile energy, a sleeve 16 is rotatably supported to a limited extent on the barrel 11, being axially fixed by a cross pin 17 which engages in an outer circumferential annular groove 18. In the sleeve 16, three longitudinal channels 19 are incorporated evenly distributed around the circumference into the inner surface, each of which merges into a transverse bore 20 at its end facing the barrel mouth, which penetrates the sleeve wall and which opens into the expansion space 15. With the corresponding angular position of the sleeve 16 relative to the barrel 11, the channels 19 each cover one of the transverse bores 14 with their end adjacent to the closure 13 the longitudinal channels 19 are offset tangentially to the transverse bores 14 and thereby closed. In order to achieve a seal between the sleeve and the barrel, the opposing surfaces can be designed in the manner of a labyrinth seal.

Der Expansionsraum 15 ist nach aussen hin durch einen Rohrabschnitt 21 begrenzt, der in seinem dem Verschluss 13 benachbarten Bereich auf die Hülse 16 passend aufschiebbar ist, wobei in eine Ringnut ein Dichtring 22 eingelegt ist. Der Rohrabschnitt 21 ist mit einer Innenverzahnung 23 und die Hülse 16 ist mit einer Aussenverzahnung 24 versehen, die miteinander in Eingriff sind, wenn der Rohrabschnitt 21 aufgesteckt ist. Durch Drehen des Rohrabschnittes 21 lässt sich somit auch die Hülse 16 verdrehen. Das andere, der Mündung des Laufes 11 benachbarte Ende des Rohrabschnittes 21 ist durch einen Ring 25 abgeschlossen, an dem auch der Mündungsschalldämpfer 9 mit seinem dem Verschluss 13 zugewandten Ende befestigt ist. Der Ring 25 ist auf den Mündungsbereich des Laufes 11 axial aufschiebbar und, durch einen Stift 26 begrenzt, um einen vorgegebenen Winkel verschwenkbar. Innerhalb des Expansionsraumes 15 ist an dem Lauf ein Stützring 27 befestigt, an dem eine Schraubendruckfeder 28 anliegt, die sich andererseits an der ihr zugewandten Stirnfläche des Ringes 25 abstützt. In den Ring 25 und den Lauf 11 ist ein Renkverschluss 32/33 eingearbeitet, dessen Schwenkwinkel durch den Stift 26 begrenzt ist. Wenn der Renkverschluss gelöst wird, drückt die Feder 28 den Ring 25 und damit den Rohrabschnitt 21 in Schussrichtung.The expansion space 15 is bounded on the outside by a tube section 21, which can be slid onto the sleeve 16 in its area adjacent to the closure 13, a sealing ring 22 being inserted into an annular groove. The pipe section 21 is provided with an internal toothing 23 and the sleeve 16 is provided with an external toothing 24 which are in engagement with one another when the pipe section 21 is attached. By rotating the pipe section 21, the sleeve 16 can thus also be rotated. The other end of the tube section 21, which is adjacent to the mouth of the barrel 11, is closed by a ring 25, to which the muffler muffler 9 is also fastened with its end facing the closure 13. The ring 25 can be slid axially onto the mouth region of the barrel 11 and, limited by a pin 26, can be pivoted through a predetermined angle. Within the expansion space 15, a support ring 27 is fastened to the barrel, on which a helical compression spring 28 rests, which is supported on the other hand on the end face of the ring 25 facing it. In the ring 25 and the barrel 11, a bayonet lock 32/33 is incorporated, the pivot angle of which is limited by the pin 26. When the bayonet lock is released, the spring 28 presses the ring 25 and thus the pipe section 21 in the weft direction.

Der Lauf 11 ist an seiner Aussenoberfläche im Bereich des vorderen Endes der Hülse 16 mit Längsnuten 29 versehen, die beim Aufschieben der Hülse 16 deren Axialstege 30 aufnehmen und so die radiale Relativlage der Hülse 16 zum Lauf 11 fixieren. Die in den Figuren 3, 4 und 5 dargestellte - jeweils gleiche - Raststellung entspricht der Stellung für unreduzierte volle Geschossenergie: die Querbohrungen 14 sind durch die Hülse 16 abgedeckt. Wird nun durch Drehen des Rohrabschnittes 21 die Hülse 16 über die Verzahnung 23/24 mitgenommen, dann bewirkt das Verdrehen im Uhrzeigersinn in Fig. 4 und 5, dass die Querbohrungen 14 von den Kanälen 19 überdeckt werden, was der Stellung für reduzierte Geschossenergie entspricht. Bei einer Drehung im Gegenuhrzeigersinn, ausgehend von Fig. 4 und 5, bleiben die Querbohrungen 14 durch die Hülse 16 abgedeckt - am Ring 25 und Lauf 11 kehren die Einrenkelemente in die Ausgangslage zurück und der Mündungsschalldämpfer 9 kann zusammen mit dem Rohrabschnitt 21 axial vom Lauf 11 abgezogen werden kann, wobei die Verzahnungen 23, 24 ausser Eingriff kommen.The barrel 11 is provided on its outer surface in the region of the front end of the sleeve 16 with longitudinal grooves 29 which receive the axial webs 30 when the sleeve 16 is pushed on and thus fix the radial position of the sleeve 16 relative to the barrel 11. The - in each case the same - locking position shown in Figures 3, 4 and 5 corresponds to the position for unreduced full projectile energy: the transverse bores 14 are covered by the sleeve 16. If the sleeve 16 is now taken along via the toothing 23/24 by rotating the pipe section 21, then the clockwise rotation in FIGS. 4 and 5 causes the transverse bores 14 to be covered by the channels 19, which corresponds to the position for reduced projectile energy. 4 and 5, the transverse bores 14 remain covered by the sleeve 16 - on the ring 25 and barrel 11, the restraining elements return to the starting position and the muffler 9 together with the pipe section 21 can axially from the barrel 11 can be withdrawn, the teeth 23, 24 coming out of engagement.

Da bei der Abgabe von Feuerstössen der Rohrabschnitt 21 eine erhöhte Temperatur annehmen kann, wird üblicherweise der Handschutz 10 aufgesteckt, der den Rohrabschnitt 21 abdeckt und vorzugsweise mit dem Rohrabschnitt 21 drehstarr verbunden ist.Since the tube section 21 can assume an increased temperature when firing bursts of fire, the hand protection 10 is usually attached, which covers the tube section 21 and is preferably connected to the tube section 21 in a rotationally rigid manner.

Der Ring 25 ist axial durchbohrt, um eine unmittelbare Verbindung vom Expansionsraum 15 zum Inneren des Mündungsschalldämpfers 9 herzustellen, dessen Innenraum seinerseits in bekannter Weise nach aussen entlüftet ist.The ring 25 is drilled axially to produce a direct connection from the expansion space 15 to the interior of the muffler 9, the interior of which in turn is vented to the outside in a known manner.

Claims (3)

1. Hand firearm with a muzzle silencer and a transversely bored barrel (11), with a closure device for optional closure of the path outwardly from the transverse bore (14), the closure device being a sleeve (16) encircling the barrel (11) and being mounted to rotate thereon, and being provided with an actuating member for adjusting the open position or closed position, the sleeve (16) having a port (19) adapted to be brought into a position coincident with the transverse bore (14), characterised in that an expansion chamber (15) is provided which is bounded by a tube portion (21) which serves as a sleeve actuating member and which, with a gap, passes around and over at least a part of the length of the barrel (11), the two ends of the tube portion (21) being connected in seal-tight fashion to the barrel and in that the tube portion (21) is rotatably mounted on the barrel (11) and is rotationally rigidly connected to the sleeve (16) via a form-locking coupling (23, 24) which can be disengaged by axial displacement and in that the tube portion (21) can be fitted on together with the muzzle silencer (9) which has to be connected in front of the barrel muzzle, and in that the tube portion and the muzzle silencer are provided with a common connector (25) which is adapted for connection to the barrel (1) in the region of the muzzle by a bayonet type connection, and in that the arrangement is so contrived that when the tube portion (21) is rotated into the position in which the muzzle silencer (9), together with the tube portion (21), can be pulled axially off the barrel (11), the transverse bore (14) is covered by the sleeve (16) and does not communicate with the port (19).
2. Hand firearm according to Claim 1, in which the sleeve (16) is on its inner surface provided with machined longitudinal ports (19), of which one end extends into the region of the transverse bores (14) machined into the barrel (11), characterised in that the longitudinal ports (19), at the other end of the sleeve, discharge into transverse bores (20) which pass through the sleeve wall.
3. Hand firearm according to Claim 1 or 2, characterised in that a hand guard (10) is fitted onto the tube portion (21).
