Description

Die vorliegende Erfindung betrifft ein Obergehäuse für eine Feuerwaffe, umfassend einen Tragteil, welcher eine Laufbuchse zur Aufnahme eines Laufs, eine Führung für einen längsverschieblichen Verschlussträger und eine Verankerung für eine Visiereinrichtung lagert, wie zum Beispiel in US2017/0314880 A beschrieben.The present invention relates to an upper housing for a firearm, comprising a supporting part which supports a barrel liner for receiving a barrel, a guide for a longitudinally displaceable bolt carrier and an anchorage for a sighting device, such as in US2017/0314880A described.

Im Stand der Technik sind Obergehäuse für Feuerwaffen, z.B. Maschinengewehre, aus Kunststoff bekannt, in welchen die Laufbuchse, die Verschlussträgerführung und die Visierverankerung als einzelne Teile eingebettet sind. Bei Erwärmung der Feuerwaffe, z.B. längerem Dauerfeuer, verformt sich der Kunststoff und kehrt nicht mehr in seine Ausgangslage zurück. Die Waffe ist dann fehljustiert und schlimmstenfalls können Funktionsstörungen auftreten, bis hin zur Unbrauchbarkeit der Waffe.In the state of the art, upper housings for firearms, e.g. When the firearm heats up, e.g. prolonged sustained fire, the plastic deforms and no longer returns to its original position. The weapon is then misaligned and, in the worst case, malfunctions can occur, up to and including the weapon being unusable.

Die Erfindung setzt sich zum Ziel, die Nachteile des genannten Standes der Technik zu überwinden und ein Obergehäuse für eine Feuerwaffe zu schaffen, welches auch bei starker Beanspruchung hohe Zielgenauigkeit und Funktionssicherheit bietet.The aim of the invention is to overcome the disadvantages of the prior art mentioned and to create an upper housing for a firearm which offers high accuracy and functional reliability even under heavy loads.

Dieses Ziel wird mit einem Obergehäuse der einleitend genannten Art erreicht, das sich gemäß der Erfindung dadurch auszeichnet, dass das Obergehäuse einen Schienenblock umfasst und, dass die Führung für den Verschlussträger an der Unterseite eines Schienenblocks aus Metall ausgebildet ist, welcher an seiner Oberseite die Verankerung für die Visiereinrichtung darbietet, wobei der Tragteil aus Metall gefertigt und einerseits mit der Laufbuchse und anderseits mit dem Schienenblock verschraubt ist.This goal is achieved with an upper housing of the type mentioned in the introduction, which is characterized according to the invention in that the upper housing comprises a rail block and that the guide for the bolt carrier is formed on the underside of a rail block made of metal, which has the anchoring on its upper side for the sighting device, the supporting part being made of metal and screwed to the bushing on the one hand and to the rail block on the other hand.

Gemäß der Erfindung sind die Verschlussträgerführung und die Visierverankerung in einem gemeinsamen Schienenblock realisiert, welcher über den Tragteil aus Metall starr mit der Laufbuchse verschraubt ist. Dadurch ist die Visiereinrichtung hochfest mit der Laufbuchse verbunden, sodass selbst bei starker Beanspruchung eine Materialdrift und damit Fehljustierung verhindert wird. Gleichzeitig ist die Verschlussträgerführung als Teil des Schienenblocks über den Tragteil hochfest mit der Laufbuchse verbunden, was Funktionsstörungen auch bei längerem Betrieb der Waffe hintanhält. Im Ergebnis wird ein Obergehäuse mit hoher Zielgenauigkeit und Funktionssicherheit erreicht.According to the invention, the bolt carrier guide and the sight anchorage are realized in a common rail block, which is rigidly screwed to the barrel via the metal support part. As a result, the sighting device is connected to the bushing with high strength, so that material drift and thus incorrect adjustment is prevented even under heavy loads. At the same time, the bolt carrier guide is high-strength as part of the rail block via the supporting part Barrel connected, which prevents malfunctions even with prolonged use of the weapon. The result is an upper housing with high accuracy and functional reliability.

Besonders günstig ist es, wenn der Tragteil durch zwei Gehäusehälften aus Metall gebildet ist, welche zwischeneinander die Laufbuchse und den Schienenblock aufnehmen, wobei die Oberseite des Schienenblocks freiliegt, und welche Gehäusehälften jeweils mit der Laufbuchse und dem Schienenblock verschraubt sind. Die Gehäusehälften lassen sich einfach fertigen, z.B. durch Fräsen, und brauchen beim Zusammenbau der Waffe lediglich mit der Laufbuchse und dem Schienenblock verschraubt werden. Auch das Zerlegen der Waffe gestaltet sich durch Lösen der Schraubverbindungen und Trennen der beiden Gehäusehälften sehr einfach.It is particularly favorable if the supporting part is formed by two housing halves made of metal, which accommodate the bushing and the rail block between one another, with the upper side of the rail block being exposed, and which housing halves are each screwed to the bushing and the rail block. The housing halves can be easily manufactured, e.g. by milling, and only need to be screwed to the liner and the rail block when the weapon is assembled. Disassembling the weapon is also very easy by loosening the screw connections and separating the two halves of the housing.

Gemäß einem bevorzugten Merkmal der Erfindung überlappt der Schienenblock die Laufbuchse teilweise, wobei die Laufbuchse mittels den Schienenblock im Überlappungsbereich durchsetzender Schrauben mit dem Tragteil verschraubt ist. Die die Laufbuchse mit dem Tragteil verbindenden Schrauben fixieren so gleichzeitig den Schienenblock im Tragteil.According to a preferred feature of the invention, the rail block partially overlaps the bushing, the bushing being screwed to the supporting part by means of screws passing through the rail block in the overlapping area. The screws connecting the bushing to the supporting part thus fix the rail block in the supporting part at the same time.

Bevorzugt haben dabei der Schienenblock und die Laufbuchse in ihrem Überlappungsbereich fluchtende Bohrungen, in welche ein Passstift eingesetzt ist, was den Zusammenbau der Waffe erleichtert. Mittels des Passstifts können zunächst Schienenblock und Laufbuchse relativ zueinander ausgerichtet und temporär fixiert und dann gemeinsam mit dem Tragteil bzw. den Gehäusehälften verschraubt werden.The rail block and the liner preferably have aligned bores in their overlapping area, in which a dowel pin is inserted, which facilitates the assembly of the weapon. By means of the dowel pin, the rail block and the bushing can first be aligned relative to one another and temporarily fixed and then screwed together with the supporting part or the housing halves.

Die Visiereinrichtung könnte direkt an der hiefür vorgesehen Verankerung an der Oberseite des Schienenblocks montiert werden. Die Visierverankerung des Schienenblocks kann dazu beispielsweise direkt in Form einer Picatinny-Schiene ausgeführt sein. Gemäß einer bevorzugten Variante wird jedoch vorgesehen, dass die Verankerung zumindest eine Schwalbenschwanzführung für eine Picatinny-Schiene zur lösbaren Montage der Visiereinrichtung aufweist, sodass verschiedenste kommerziell erhältliche Picatinny-Schienen verwendet werden können.The sight could be mounted directly to the anchorage provided for this purpose on the top of the rail block. The visor anchorage of the rail block can, for example, be designed directly in the form of a Picatinny rail. According to a preferred variant, however, it is provided that the anchorage has at least one dovetail guide for a Picatinny rail for the detachable mounting of the sighting device has, so that a wide variety of commercially available Picatinny rails can be used.

In einer weiteren bevorzugten Ausgestaltung der Erfindung weist der Tragteil eine Kulisse für einen Steuerbolzen eines im Verschlussträger beweglichen Verschlusses auf. Beispielsweise enthält der Verschlussträger einen in der Laufbuchse drehverriegelbaren Verschlusskopf, und der Steuerbolzen des Verschlusskopfes greift so in die Kulisse des Tragteils ein, dass er beim Repetieren der Waffe entsprechend aus der Laufbuchse gelöst (entriegelt) und anschließend wieder darin drehverriegelt wird, wie in der Technik bekannt.In a further preferred embodiment of the invention, the supporting part has a connecting link for a control pin of a lock that can be moved in the lock carrier. For example, the bolt carrier contains a bolt head that can be rotated in the barrel, and the control bolt of the bolt head engages in the connecting link of the carrying part in such a way that it is released (unlocked) from the barrel when the weapon is repeated and then locked in again by turning, as in technology known.

Besonders günstig ist es dabei, wenn die Kulisse mit einer Verstärkungsschiene verstärkt ist, die aus einem vom Metall des Tragteils verschiedenen Material gefertigt ist, bevorzugt aus Stahl. Die Verstärkungsschiene kann beispielsweise in den Tragteil eingelassen sein oder wird insbesondere auf die Innenseite einer Gehäusehälfte aufgeschraubt. Beim Repetieren des Verschlusses übt der Steuerbolzen eine schlagartige und hohe Kraft auf die Kulisse aus, welche durch die Verstärkungsschiene abgefangen wird, um Verschleißerscheinungen hintanzuhalten.It is particularly favorable if the connecting link is reinforced with a reinforcement rail that is made of a material that is different from the metal of the supporting part, preferably steel. The reinforcing rail can be embedded in the support part, for example, or is screwed onto the inside of a housing half, in particular. When repeating the breech, the control bolt exerts an abrupt and high force on the connecting link, which is intercepted by the reinforcement rail in order to prevent signs of wear.

Vorteilhafterweise ist der Tragteil aus Leichtmetall, bevorzugt Aluminium, gefertigt, was hohe Verformungsfestigkeit bei geringem Gewicht ergibt.Advantageously, the support part is made of light metal, preferably aluminum, which results in high deformation resistance with low weight.

Wenn der Tragteil aus zwei Gehäusehälften gebildet ist, können diese besonders einfach auch zur Verankerung weiterer Teile der Waffe verwendet werden. Beispielsweise können die Gehäusehälften zwischeneinander einen nach unten auskragenden Magazinhalter aufnehmen und mit diesem verschraubt sein, was einen einfachen Zusammenbau ermöglicht.If the supporting part is formed from two housing halves, these can also be used particularly easily to anchor other parts of the weapon. For example, the housing halves can accommodate a downwardly projecting magazine holder between one another and be screwed to this, which enables simple assembly.

Die Erfindung wird nachstehend anhand eines in den beigeschlossenen Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. In den Zeichnungen zeigen:

In den Fig. 1 - 6 ist ein Obergehäuse 1 für eine (nicht weiter dargestellte) Feuerwaffe gezeigt. Das Obergehäuse 1 umfasst einen aus Metall gefertigten Tragteil 2, der einstückig oder (wie hier gezeigt) aus zwei Gehäusehälften 3', 3" zusammengesetzt sein kann. In dem Tragteil 2 bzw. zwischen den Gehäusehälften 3', 3" sind eine Laufbuchse 4 zur Aufnahme eines (nicht gezeigten) Laufs und ein Schienenblock 5 aus Metall angeordnet, welcher mehrere Funktionen hat: Zum einen weist der Schienenblock 5 an seiner Unterseite eine Führung 6 für einen Verschlussträger 7 auf, der in der Führung 6 längsverschieblich bezüglich des Tragteils 2 und der Laufbuchse 4 ist. Zum anderen ist der Schienenblock 5 an seiner Oberseite mit einer Verankerung 8 für eine (nicht dargestellte) Visiereinrichtung ausgestattet. Darüber hinaus bildet der Schienenblock 5, wenn der Tragteil 2 in Form von zwei seitenplattenartigen Gehäusehälften 3', 3" ausgebildet ist, den oberen Abschluss des Obergehäuse 1, d.h. bildet gemeinsam mit den Gehäusehälften 3', 3" ein im Querschnitt etwa U-förmiges, nach unten hin offenes Obergehäuse 1.In the Figures 1 - 6 an upper housing 1 for a (not shown) firearm is shown. The upper housing 1 comprises a support part 2 made of metal, which can be in one piece or (as shown here) composed of two housing halves 3', 3". In the support part 2 or between the housing halves 3', 3" are a bushing 4 for Accommodating a barrel (not shown) and a rail block 5 made of metal, which has several functions: On the one hand, the rail block 5 has a guide 6 on its underside for a bolt carrier 7, which can be displaced longitudinally in the guide 6 with respect to the supporting part 2 and the Liner 4 is. On the other hand, the top of the rail block 5 is equipped with an anchorage 8 for a sighting device (not shown). In addition, if the supporting part 2 is designed in the form of two side-plate-like housing halves 3', 3", the rail block 5 forms the upper end of the upper housing 1, ie together with the housing halves 3', 3" it forms an approximately U-shaped cross section , upper case open towards the bottom 1.

Die Begriffe "unten" und "oben" beziehen sich hierbei auf die normale Verwendungsstellung der Waffe, wie sie in den Fig. 1, 3 und 4 gezeigt ist. Die Begriffe "längsverschieblich" und "Längsrichtung" beziehen sich auf die Laufrichtung bzw. -achse der Waffe. Die Begriffe "vorne" und "rückwärts" beziehen sich auf die Laufmündungsseite (vorne) bzw. Schützenseite (rückwärts) der Waffe. Die Begriffe "links" und "rechts" beziehen sich auf die Blickrichtung des Schützen beim Schießen.The terms "down" and "up" here refer to the normal position of use of the weapon, as in the 1 , 3 and 4 is shown. The terms "longitudinally displaceable" and "longitudinal direction" relate to the running direction or axis of the weapon. The terms "front" and "back" refer to the muzzle side (front) and shooter side (back) of the gun, respectively. The terms "left" and "right" refer to the shooter's line of sight when shooting.

Die Laufbuchse 4 besitzt eine zentrale Bohrung 9 zur Aufnahme des rückwärtigen Endes des Laufes (nicht gezeigt), der beispielsweise mit Hilfe einer Überwurfmutter mit einem Außengewinde 10 der Laufbuchse 4 verschraubt werden kann. An ihrer Rückseite hat die Laufbuchse 9 einen Kranz von Bajonettnuten 11, mit denen ein im Verschlussträger 7 längsverschieblich und drehbar gelagerter zahnkranzartiger Verschlusskopf drehverriegelt werden kann, wie in der Technik bekannt.The liner 4 has a central bore 9 for receiving the rear end of the barrel (not shown), which can be screwed to an external thread 10 of the liner 4, for example with the aid of a union nut. On its rear side, the liner 9 has a ring of bayonet grooves 11, with which a toothed ring-like breech head, which is mounted in the breech carrier 7 in a longitudinally displaceable and rotatable manner, can be rotationally locked, as is known in the art.

Die Verschlussträgerführung 6 an der Unterseite des Schienenblocks 5 ist im gezeigten Beispiel eine T-Nut, in der ein im Profil T-förmiger Oberteil 12 des Verschlussträgers 7 gleitend geführt ist. Die Verschlussträgerführung 6 könnte jedoch auch eine andere Querschnittsform haben, welche mit einem entsprechend komplementär ausgebildeten Teil des Verschlussträgers 7 zusammenwirkt, und diesen längsverschieblich im Obergehäuse 1 zu lagern.In the example shown, the bolt carrier guide 6 on the underside of the rail block 5 is a T-groove in which an upper part 12 of the bolt carrier 7 with a T-shaped profile is slidably guided. However, the bolt carrier guide 6 could also have a different cross-sectional shape, which interacts with a correspondingly complementary part of the bolt carrier 7 and supports this in the upper housing 1 in a longitudinally displaceable manner.

Die Visierverankerung 8 des Schienenblocks 5 kann beispielsweise durch Bohrungen, Laschen, Hinterschneidungen od.dgl. an der Oberseite des Schienenblocks 5 gebildet sein. Im gezeigten Beispiel umfasst die Visierverankerung 8 mehrere über die Längsrichtung des Schienenblocks 5 verteilte Schwalbenschwanzführungen, auf welche eine Picatinny-Schiene (nicht gezeigt) mit unterseitiger Schwalbenschwanznut aufgeschoben werden kann; auf der Picatinny-Schiene können dann in an sich bekannter Weise die Visiereinrichtung verstellbar und lösbar montiert werden, ebenso wie andere Anbauteile der Waffe, z.B. Granatwerfer, Bajonette, Laserpointer, Scheinwerfer usw.The visor anchorage 8 of the rail block 5 can, for example, through holes, tabs, undercuts or the like. be formed at the top of the rail block 5. In the example shown, the visor anchorage 8 comprises a plurality of dovetail guides distributed over the longitudinal direction of the rail block 5, onto which a Picatinny rail (not shown) with a dovetail groove on the underside can be slid; The sighting device can then be mounted on the Picatinny rail in an adjustable and detachable manner, as can other add-on parts of the weapon, e.g. grenade launchers, bayonets, laser pointers, searchlights, etc.

An dem Obergehäuse 1, genauer dem Tragteil 2, werden in der Regel auch die weiteren Komponenten der Waffe montiert, z.B. ein Vorderschaft im Bereich 13 vor dem Obergehäuse 1, ein Magazin im Bereich 14 unter dem Obergehäuse 1, eine Abzugsgruppe im Bereich 15 unter dem Obergehäuse 1 und ein Schaft oder eine Schulterstütze im Bereich 16 rückwärts des Obergehäuses 1. Für die Verankerung dieser Waffenkomponenten kann das Obergehäuse 1 beispielsweise einen Vorderschaft-Anbindungsblock 17 enthalten, der zwischen den Gehäusehälften 3', 3" nach unten auskragend aufgenommen und mittels Schrauben 18 mit diesen verschraubt ist; einen zwischen den Gehäusehälften 3', 3" aufgenommenen, nach unten auskragenden Magazinhalter 19, der mittels Schrauben 20 mit diesen verschraubt ist; ein Scharnier 21 mit Scharnierstift 22 im rückwärtigen Bereich des Obergehäuses 1, beispielsweise am rückwärtigen Ende der rechten Gehäusehälfte 3", um dort eine klappbare Schulterstütze oder einen Klappschaft anzulenken; sowie eine Aufnahme 23 mit Verankerungsbohrungen 24 zur Verankerung einer Abzugsgruppe im Bereich 15, die mit dem Verschlussträger 7 und dem darin geführten Verschlusskopf zusammenwirkt. Mittels eines Kerbstiftes 25, welcher die Wandung der Laufbuchse 4 durchsetzt und in eine entsprechende Ausnehmung des (nicht gezeigten) Laufs eingreift, kann der Lauf in seiner Drehrichtung ausgerichtet werden.The other components of the weapon are usually also mounted on the upper housing 1, more precisely the carrying part 2, e.g Upper housing 1 and a stock or a stock in the area 16 to the rear of the upper housing 1. For the anchoring of these weapon components, the upper housing 1 can, for example, have a fore-end connection block 17 included, which is received between the housing halves 3', 3" in a downwardly projecting manner and is screwed to them by means of screws 18; a magazine holder 19 which is received between the housing halves 3', 3" and projects downwards and is screwed to them by means of screws 20; a hinge 21 with a hinge pin 22 in the rear area of the upper housing 1, for example at the rear end of the right-hand housing half 3", in order to articulate a foldable buttstock or a folding stock there; and a receptacle 23 with anchoring bores 24 for anchoring a trigger group in area 15, which is The barrel can be aligned in its direction of rotation by means of a grooved pin 25, which penetrates the wall of the barrel bushing 4 and engages in a corresponding recess of the barrel (not shown).

Durch die Ausbildung der Verschlussträgerführung 6 und der Visierverankerung 8 am gemeinsamen Schienenblock 5 sind die Verschlussträgerführung 6 und die Visiereinrichtung 8 zueinander starr lagefixiert. Durch Verschrauben sowohl der Laufbuchse 4 als auch des Schienenblocks 5 mit dem gemeinsamen Tragteil 2, genauer: jeweils mit jeder der Gehäusehälften 3', 3", ist auch die Laufbuchse 4 gegenüber der Verschlussträgerführung 6 und gegenüber der Visierverankerung 8 starr lagefixiert. Dadurch ergibt sich eine stabile Justierung der Visierverankerung 8 gegenüber dem in der Laufbuchse 4 aufgenommenen Lauf und damit eine maßhaltige dauerhafte Justierung des Visiers zum Lauf.Due to the design of the bolt carrier guide 6 and the sight anchorage 8 on the common rail block 5, the bolt carrier guide 6 and the sight device 8 are rigidly fixed in position relative to one another. By screwing both the bushing 4 and the rail block 5 to the common support part 2, more precisely: to each of the housing halves 3', 3", the bushing 4 is also rigidly fixed in position relative to the bolt carrier guide 6 and relative to the sight anchorage 8. This results in a stable adjustment of the visor anchorage 8 relative to the barrel accommodated in the liner 4 and thus a dimensionally stable permanent adjustment of the visor to the barrel.

Die Verschraubung des Schienenblocks 5 mit dem Tragteil 2 bzw. den Gehäusehälften 3', 3" erfolgt mittels eines Satzes von Schrauben 26, welche jeweils seitliche Bohrungen 27 der Gehäusehälften 3', 3" durchsetzen und in entsprechende Gewindebohrungen 28 des Schienenblocks 5 eingreifen. Die Verschraubung der Laufbuchse 4 mit dem Tragteil 2 bzw. den Gehäusehälften 3', 3" kann mittels gesonderter Schrauben erfolgen oder - wie gezeigt - können dazu einige der Schrauben 26 mitverwendet werden. Dazu überlappt der Schienenblock 5 mit zwei nach unten gerichteten Ansätzen 29 den oberen Teil 30 der Laufbuchse 4. In diesem Überlappungsbereich durchsetzen die Schrauben 26 die Bohrungen 28 in den Ansätzen 29 des Schienenblocks 5 und greifen in Gewindebohrungen 31 im oberen Teil 30 der Laufbuchse 4 ein. Die Laufbuchse 4 wird so gleichzeitig mit dem Schienenblock 5 im Tragteil 2 mitfixiert.The rail block 5 is screwed to the support part 2 or the housing halves 3', 3" by means of a set of screws 26, which pass through lateral bores 27 in the housing halves 3', 3" and engage in corresponding threaded bores 28 in the rail block 5. The bushing 4 can be screwed to the supporting part 2 or the housing halves 3′, 3″ using separate screws or—as shown—some of the screws 26 can also be used for this purpose Approaches 29 the upper part 30 of the liner 4. In this overlapping area, the screws 26 pass through the holes 28 in the lugs 29 of the rail block 5 and engage in threaded holes 31 in the upper part 30 of the liner 4 a. The bushing 4 is thus fixed in the support part 2 at the same time as the rail block 5 .

Um das Zusammenschrauben zu erleichtern, kann die Laufbuchse 4 am Schienenblock 5 vorfixiert werden. Dazu haben der Schienenblock 5 und die Laufbuchse 4 im Überlappungsbereich fluchtende Bohrungen 32, 33, in welche ein Passstift 34 einsetzbar ist, der die Laufbuchse 4 temporär zwischen den Ansätzen 29 des Schienenblocks 5 hält, bis dieser mittels der Schrauben 26 mit den Gehäusehälften 3', 3" verschraubt ist. Im verschraubten Zustand halten die Gehäusehälften 3', 3" den Passstift 34 zwischeneinander fest.In order to facilitate screwing together, the bushing 4 can be pre-fixed to the rail block 5. For this purpose, the rail block 5 and the bushing 4 have aligned bores 32, 33 in the overlapping area, into which a dowel pin 34 can be inserted, which temporarily holds the bushing 4 between the shoulders 29 of the rail block 5 until it is connected to the housing halves 3' by means of the screws 26. , 3" is screwed together. In the screwed together state, the housing halves 3', 3" hold the dowel pin 34 firmly between one another.

Zum Ver- und Entriegeln des im Verschlussträger 7 geführten Verschlusskopfes weist der Tragteil 2 an seiner Innenseite, hier insbesondere an der linken Gehäusehälfte 3', eine Kulisse 35 für einen Steuerbolzen 36 des im Verschlussträger 7 geführten Verschlusses bzw. Verschlusskopf auf. Die Kulisse 35 ist im gezeigten Beispiel eine in Längsrichtung der Waffe verlaufende Nut an der Innenseite der Gehäusehälfte 3'. Zur Verstärkung der Kulisse 35 kann diese mit einem Einsatz aus einem härteren Material als der Tragteil 2 verstärkt sein, beispielsweise aus Stahl, wenn der Tragteil 2 z.B. aus Leichtmetall, wie Aluminium, gefertigt ist. Im gezeigten Beispiel ist zur Verstärkung der Kulisse 35 eine Verstärkungsschiene 37 vorgesehen, welche einen Abschnitt der oberen Seitenwandung der Kulissennut bildet und mittels Schrauben 38 mit der Gehäusehälfte 3' verschraubt ist.For locking and unlocking the bolt head guided in the bolt carrier 7 , the supporting part 2 has on its inside, here in particular on the left housing half 3 ′, a link 35 for a control pin 36 of the bolt or bolt head guided in the bolt carrier 7 . In the example shown, link 35 is a groove running in the longitudinal direction of the weapon on the inside of housing half 3'. In order to strengthen the link 35, it can be reinforced with an insert made of a harder material than the supporting part 2, for example steel if the supporting part 2 is made of light metal, such as aluminum, for example. In the example shown, a reinforcement rail 37 is provided to reinforce the gate 35, which forms a section of the upper side wall of the gate groove and is screwed to the housing half 3' by means of screws 38.

Anstelle einer solchen abschnittsweisen Verstärkungsschiene 37 könnte auch die gesamte Kulisse 35 aus einem Einsatz aus härterem Material als die Gehäusehälfte 3', z.B. aus Hartstahl, gefertigt sein.Instead of such a reinforcing rail 37 in sections, the entire connecting link 35 could also be made from an insert made of a harder material than the housing half 3', for example hard steel.
