Abstract

The test-firing apparatus comprises a weapon-holder (WH) accommodating a rifle or hand-gun and a preferably freely mobile mounting (LG), for the said holder, in relation to a stationary base (S). A projecting support means (SA), connected to the weapon, allows the recoil-pulse to be absorbed, in conjunction with the freely mobile mounting, by the body of an operator, as in practical shooting. The only purpose of the mounting, preferably in the form of a linear precision guide comprising cross rollers, is to position the barrel-axis directionally, and the said mounting is therefore subjected to little stress. Resilient and/or damping absorption of the recoil-pulse may also be provided. The barrel-axis (X-X) is arranged in parallel with the movement-axis (Y-Y) of the mounting, so that the point of impact of the bullet upon the target cannot be affected by the recoil-stroke. This parallelism may be adjusted by optical means, preferably by means of a reference-weapon fitted to the weapon-holder, the barrel-axis of the said reference-weapon being fixed parallel with the movement-axis by means of appropriate indexing elements. This indirect alignment is achieved by comparing the shot-patterns of the two weapons.

Description

Die Erfindung betrifft eine Einrichtung zur Schussprüfung von Hand- und Faustfeuerwaffen, mit einer festsetz- unf lösbaren, drehfrei gelagerten Waffenhalterung, die an einem Sockel abgestützt und in bezug auf den Sockel in Rückstossrichtung der zu prüfenden Waffe entlang einer Lagerungsachse beweglich gelagert ist, wobei die Laufachse der Waffe mindestens annähernd parallel zu der Lagerungsachse angeordnet ist, und wobei die Waffenhalterung mindestens eine Waffen aufnahme und eine zur Anlage mit dem Kolbenende bestimmte Stützanlage aufweist.The invention relates to a device for shooting testing of hand and hand guns, with a fixable and detachable, non-rotatably mounted weapon holder, which is supported on a base and is movably mounted in relation to the base in the recoil direction of the weapon to be tested along a bearing axis, the Barrel axis of the weapon is arranged at least approximately parallel to the bearing axis, and wherein the weapon holder accommodates at least one weapon and has a support system intended for contact with the piston end.

Es sind Einrichtungen in Form von Starrbock-Konstruktionen mit einer Einspannvorrichtung für die zu prüfende Waffe bekannt. Sie dienen zur Aufnahme eines Schussbildes, wobei es im wesentlichen auf die Einhaltung eines umschriebenen Kreises vorgegebenen Durchmessers in der Zielebene bei einer grösseren Schusszahl ankommt.Devices in the form of rigid-frame constructions with a clamping device for the weapon to be tested are known. They are used to take a shot image, it being essentially a matter of maintaining a circumscribed circle of predetermined diameter in the target plane with a larger number of shots.

Die übliche, starre Einspannung der zu prüfenden Waffe ermöglicht zwar eine genaue Justierung der Laufachse sowie, bei genügend stabiler Konstruktion, auch eine gewisse Konstanz der Lageeinstellung. Andererseits führt die unvermeidliche, elastische Verformung der Bock-Konstruktion infolge des Rückstossimpulses wegen der hohen Verformungssteifigkeit zu vergleichsweise hochfrequenten Schwingungen sowohl in der Waffenhalterung wie auch in der Waffe selbst, insbesondere innerhalb des Laufes. Damit sind nicht nur Unannehmlichkeiten bei längerem Gebrauch, sondern auch zusätzliche, an sich nicht durch die Eigenschaften der Waffe bedingte Streuungen verbunden. Ausserdem liefert eine Schussprüfung mit einer solchen Starreinspannung zwar aussagekräftige Ergebnisse bezüglich der zu prüfenden Waffe unter standardisierten Bedingungen, nicht aber praxisgerechte Ergebnisse, die den Verhältnissen mit Abstützung und Rückstossaufnahme durch den Körper des Schützen entsprechen.The usual, rigid clamping of the weapon to be tested allows precise adjustment of the barrel axis and, with a sufficiently stable construction, also a certain consistency of the position setting. On the other hand, the inevitable, elastic deformation of the Bock construction as a result of the recoil impulse, because of the high deformation rigidity, leads to comparatively high-frequency vibrations both in the weapon holder and in the weapon itself, especially within the barrel. Not only are there inconveniences from prolonged use, but also additional scattering that is not inherent in the properties of the weapon. In addition, a shot test with such a staring tension provides meaningful results with regard to the weapon under test under standardized conditions, but not practical results that correspond to the conditions with support and recoil absorption by the shooter's body.

Aus der US-A-3 805 608 ist eine gattungsgemässe Einrichtung bekannt, bei der die Waffenhalterung in Bezug auf einen Sockel beweglich gelagert ist, wobei eine lineare, drehfreie Lagerung vorgesehen und die Laufachse der Waffe annähernd parallel zur Lagerungsachse angeordnet ist.From US-A-3 805 608 a generic device is known in which the weapon holder is movably mounted with respect to a base, a linear, non-rotating bearing is provided and the barrel axis of the weapon is arranged approximately parallel to the bearing axis.

Aus der DE-C-218 804 ist eine Einrichtung zur Schussprüfung bekannt, bei der die Waffenhalterung während des Rückstosshubes annähernd kräftefrei gelagert ist.From DE-C-218 804 a device for shot testing is known in which the weapon holder is mounted almost without force during the recoil stroke.

Bei diesen Einrichtungen fehlt jedoch eine mit der Waffe verbundene Stützanlage zur Uebertragung der Rückstosskräfte auf eine Bedienungsperson.In these devices, however, there is no support system connected to the weapon for transmitting the recoil forces to an operator.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Einrichtung zur Schussprüfung zu schaffen, die sich unter Wahrung der Möglichkeit einer genauen Richtungsjustierung der Laufachse durch hohe Konstanz der Lageeinstellung sowie durch eine praxisgerechte Rückstossaufnahme ohne hochfrequente Schwingungen im Einspann- und Waffenbereich auszeichnet.The invention seeks to remedy this. The invention, as characterized in the claims, solves the task of creating a device for shot testing, which while maintaining the possibility of an accurate directional adjustment of the barrel axis through high constancy of the position and a practical recoil absorption without high-frequency vibrations in the clamping and Weapons area.

Die mit der Erfindung erreichbaren Vorteile sind darin zu sehen, dass sich durch die Aufnahme des Rückstossimpulses nicht nur praxisgerechte Verhältnisse ergeben, sondern es werden auch Querkraftkomponenten vermieden, weil die Impulsabstützung über den Körper des Schützen ohne Kraftübertragung auf den Sockel im Bereich der Bewegungslagerung erfolgen kann. Wesentlich ist hierbei die Einhaltung der genauen Laufachseneinstellung infolge der Bewegungsführung, vorzugsweise wiederum mit Hilfe einer linearen Lagerung. Ferner ermöglicht die bewegliche Lagerung der Waffenhalterung eine elastisch-dämpfende Längsabstützung der Waffe gegen den Rückstossimpuls, so dass keine wesentlichen Schwingungen entstehen können. Der zur elastisch-dämpfenden Aufnahme des Rückstossimpulses erforderliche Bewegungshub führt dann zu keiner Verfälschung des Schussbildes.The advantages achievable with the invention are to be seen in the fact that the absorption of the recoil pulse not only results in practical conditions, but also shear force components are avoided because the pulse support via the body of the shooter can take place without force transmission to the base in the area of the movement bearing . It is important here to adhere to the precise setting of the running axes as a result of the movement control, preferably again with the aid of a linear bearing. Furthermore, the movable mounting of the weapon holder enables an elastic-damping longitudinal support of the weapon against the recoil pulse, so that no significant vibrations can occur. The movement stroke required for the elastic-damping absorption of the recoil pulse then does not lead to any distortion of the shot pattern.

Insbesondere bei Waffen mit Holz- und Kunststoffschäftung besteht im allgemeinen am Aeusseren der Waffe kein Anhalt für die Lage und Richtung der Laufachse. Um gleichwohl eine rasche und genaue Ausrichtung der Laufachse parallel zur Bewegungsbahne der Lagerung zu ermöglichen, ist gemäss einer beonderen Weiterbildung der Erfindung an der Waffenhalterung eine Aufnahme für einen mit seiner Achse parallel zur Bewegungsachse der Lagerung angeordneten Referenzlauf vorgesehen, wobei eine lineare Lagerung vorausgesetzt wird. Die Lageeinstellung der zu prüfenden Waffen kann nun indirekt durch Vergleich mit dem Referenzlauf vongenommen werden. Hierfür kommt grundsätzlich beispielsweise eine optische Feststellung eines Visierpunktes der beiden in ihrer Einstellung zu vergleichenden Läufe in Betracht. Die Lageeinstellung der zu prüfenden Waffe kann dann mit H.ilfe-'einer mechanischen Justiervorrichtung durch Vergleich der beiden Visierpunkte schnell erreicht werden.In particular with weapons with wood and plastic stock, there is generally no indication of the position and direction of the barrel axis on the outside of the weapon. In order to enable a quick and precise alignment of the barrel axis parallel to the movement path of the bearing, according to a special development of the invention, a receptacle is provided on the weapon holder for a reference run arranged with its axis parallel to the movement axis of the bearing, a linear bearing being required. The position of the weapons to be tested can now be taken indirectly by comparison with the reference run. Basically, for example, an optical determination of a sighting point of the two runs to be compared in their setting can be considered. The position of the weapon to be tested can then be quickly achieved using a mechanical adjustment device by comparing the two sighting points.

Eine besonders vorteilhafte Weiterbildung der Erfindung sieht jedoch in diesem Zusammenhang an der Waffenhalterung eine zusätzliche Aufnahme für eine funktionsfähige Waffe vor, deren Lauf als Referenzlauf dient. Der Lagevergleich der beiden Läufe kann nun besonders einfach und rasch durch Schussbildvergleich vorgenommen werden, wozu im allgemeinen nur wenige Probeschüsse erforderlich sind.However, a particularly advantageous development of the invention provides in this connection at the Waffenhalterun g an additional receptacle for a functional weapon against whose run serves as a reference run. The position comparison of the two runs can now be carried out particularly simply and quickly by comparison of the shot pattern, for which generally only a few test shots are required.

Vorzugsweise wird hierfür eine Referenzlauf-Waffe verwendet, die zwei zur Achse des Referenzlaufes koaxiale und in Laufachsenrichtung mit gegenseitigem Abstand angeordnete Halterungsflächen aufweist. Dies ermöglicht nicht nur einen einfachen Aufbau der Aufnahme für die Referenzlauf-Waffe, sondern erspart bei normalen Genauigkeitsanforderungen auch eine besondere Lagejustierung des Referenzlaufes in Bezug auf die Achse der Lagerung, weil die Halterungsflächen der Aufnahme mittels geeigneter Passelemente leicht entsprechend der gewünschten Parallel-Lage vorab fest angeordnet werden können. Geeignete, zylindrische Halterungsoder Anlageflächen sind beispielsweise bei einigen verbreiteten Automatikwaffen, insbesondere Sturmgewehren, vorhanden.A reference barrel weapon is preferably used for this purpose, which has two mounting surfaces which are coaxial to the axis of the reference barrel and are arranged at a mutual distance in the barrel axis direction. This not only enables a simple construction of the mount for the reference barrel weapon, but also saves a special position adjustment of the in the case of normal accuracy requirements Reference run with respect to the axis of the bearing, because the mounting surfaces of the receptacle can be easily arranged in advance according to the desired parallel position by means of suitable fitting elements. Suitable, cylindrical mounting or contact surfaces are available, for example, in some common automatic weapons, especially assault rifles.

  • 2 shows a cross section of the shot testing device according to the sectional plane 11-11 in FIG. 1,

Gemäss Fig. 1 umfasst die insgesamt mit WH bezeichnete Waffenhalterung eine horizontale Tragplatte TR mit einem rückwärtigen Kragarm KR. Auf der Tragplatte ist eine mit einem Klemmglied K1 versehene, bügelartige Waffenaufnahme WA befestigt, die am hinteren Laufende eines Karabiners KB als zu prüfender Waffe angreift. Das rückwärtige Ende des Kragarmes KR nimmt das Ende des Kolbens KO des Karabiners auf, und zwar gesichert durch ein zweites Klemmglied K2, welches den Kolben abwärts gegen eine als Richtungs-Justiereinrichtung YR dienende Stellschraube drückt.According to FIG. 1, the weapon holder designated overall by WH comprises a horizontal support plate TR with a rear cantilever arm KR. A bracket-like weapon receptacle WA, which is provided with a clamping member K 1 and which engages at the rear end of a carbine KB as a weapon to be tested, is fastened to the support plate. The rear end of the cantilever arm KR receives the end of the piston KO of the karabiner, and is secured by a second clamping member K 2 , which presses the piston downward against a set screw serving as a direction adjusting device YR.

Das Klemmglied K2 sitzt am oberen, rückwärts abgewinkelten Ende eines Vertikalschenkels des Kragarmes KR. Dieser Vertikalschenkel des Kragarmes ist als Stützanlage SA für die Aufnahme des Rückstossimpulses durch den Körper einer Bedienungsperson vorgesehen, wie dies im wesentlichen den praktischen Einsatzverhältnissen der Waffe entspricht. Ausserdem ist eine seitlich im unteren Bereich des Kolbenendes angreifende Stellschraube als Schwenk-Justiereinrichtung SJ vorgesehen. Die Angriffsstelle dieser Schwenk-Justiereinrichtung ist mit Abstand unterhalb der Lagerung des Karabinerlaufes in der Waffenaufnahme WA angeordnet, wodurch sich ein vertikaler Hebelarm für die Schwenkeinstellung der Waffe um die horizontale Laufachse X-X ergibt. Diese Schwenkeinstellung zum Ausgleich eines etwaigen Verkantens ist zwar für die Aufnahme eines Streubildes an sich unwesentlich, jedoch für eine etwa zusätzlich vorgenommene Anvisierung des Schusszieles erwünscht. Die Schwenk-Justiereinrichtung SJ umfasst eine nicht dargestellte, auf der gegenüberliegenden Seite angeordnete Gegenstellschraube, so dass der Kolben in Seitenrichtung arretiert werden kann. Ebenso ist das Kolbenende in Höhenrichtung zwischen der Stellschraube der Richtungs-Justiereinrichtung YR und der Schraube des Klemmgliedes K2 arretiert.The clamping member K 2 sits at the upper, angled back end of a vertical leg of the cantilever KR. This vertical leg of the cantilever arm is provided as a support system SA for the absorption of the recoil pulse by the body of an operator, as this essentially corresponds to the practical application of the weapon. In addition, an adjusting screw acting laterally in the lower region of the piston end is provided as a swivel adjusting device SJ. The point of attack of this swivel adjustment device is arranged at a distance below the mounting of the carabiner barrel in the weapon holder WA, which results in a vertical lever arm for the swivel adjustment of the weapon about the horizontal barrel axis XX. This swivel setting to compensate for any canting is in itself insignificant for the recording of a scatter pattern, but is desirable for any additional aiming of the target. The swivel adjustment device SJ comprises a counter-setting screw, not shown, arranged on the opposite side, so that the piston can be locked in the lateral direction. Likewise, the piston end is locked in the vertical direction between the adjusting screw of the direction adjusting device YR and the screw of the clamping member K 2 .

Die Waffenhalterung WA ist in der aus Fig. 1 ersichtlichen Weise mittels einer an der Unterseite der Tragplatte PR angebrachten linearen Lagerung LG in Richtung der Achse Y-Y horizontal verschiebbar auf einem Sockel S gelagert. Dieser Sockel ist mit den angedeuteten Vertikalstützen ortsfest verankert. Demgemäss kann die Waffenhalterung einen Rückstosshub x in Richtung der Pfeile P parallel zur Achse Y-Y der Lagerung LG ausführen. Dabei wird die Laufachse X-X durch gegensinniges Verdrehen der Stellschraube der Richtungs-Justiereinrichtung YR einerseits und der Schraube des Klemmgliedes K2 andererseits parallel zur Achse Y-Y eingestellt. Infolgedessen kann die Horizontalverschiebung der Waffe beim Rückstosshub keinen Einfluss auf die Trefferlage nehmen. Die Lagerung LG ist mit an sich bekannten Konstruktionselementen, beispiesweise einer Kreuzrollenanordnung, mit grosser Genauigkeit und spielfrei ausgeführt.The weapon holder WA is mounted on a base S in the manner shown in FIG. 1 by means of a linear bearing LG attached to the underside of the support plate PR in the direction of the axis YY. This base is anchored in place with the indicated vertical supports. Accordingly, the weapon holder can perform a recoil stroke x in the direction of the arrows P parallel to the axis YY of the bearing LG. The running axis XX is set parallel to the axis YY by turning the adjusting screw of the direction adjusting device YR on the one hand and the screw of the clamping member K 2 on the other hand. As a result, the horizontal displacement of the weapon during the recoil stroke cannot influence the hit position. The bearing LG is designed with known construction elements, for example a cross roller arrangement, with great accuracy and without play.

Die Waffenhalterung ist auf einem Teil des Rückstosshubes x kräftefrei gelagert, so dass der Rückstossimpuls im Anfangsabschnitt des Rückstosshubes ausschliesslich durch den Körper der Bedienungsperson aufgenommen wird, wie dies dem praktischen Schiessbetrieb entspricht. Es ergibt sich damit eine sehr wirksame und vor allem den praktischen Einsatzverhältnissen entsprechende Dämpfung, so dass keine Schwingungen der Waffe auftreten. Die Lagerung der Waffe hat also nur die Aufgabe der Richtungsfixierung und unterliegt nur geringen mechanischen Beanspruchungen.The weapon holder is mounted on part of the recoil stroke x without force, so that the recoil pulse in the initial section of the recoil stroke is absorbed exclusively by the operator's body, as is the case with practical shooting operations. This results in a very effective damping and, above all, practical conditions, so that the weapon does not vibrate. The storage of the weapon therefore only has the task of fixing the direction and is subject to only slight mechanical loads.

Zusätzlich ist auf einem Teil x. des Rückstosshubes eine Gegenfederung GF zur zusätzlichen, elastischen Abstützung des Rückstossimpulses vorgesehen. Ausserdem ist ein als Dämpfungselement ausgebildeter, beispielsweise aus dämpfenden Gummi bestehender Rückstoss-Begrenzungsanschlag RA vorgesehen, welcher einen etwa von der Bedienungsperson nicht abgestützen Impulsanteil aufnehmen kann. Grundsätzlich ist es insbesondere möglich, die Gegenfederung und Dämpfung so auszugestalten, dass sie den gesamten Rückstossimpuls aufnimmt und insoweit die Stützfunktion durch den Körper der Bedienungsperson ersetzt.In addition, on part x . of the recoil stroke, a counter-suspension GF is provided for additional, elastic support of the recoil pulse. In addition, a recoil limiting stop RA designed as a damping element, for example made of damping rubber, is provided, which can absorb an impulse component that is not supported by the operator. In principle, it is in particular possible to design the counter-springing and damping in such a way that it absorbs the entire recoil pulse and in this respect replaces the support function by the operator's body.

In der aus Fig. 2 und Fig. 4 ersichtlichen Weise umfasst die Waffenhalterung WH ferner eine Aufnahme WA1 für ein Sturmgewehr SG, dessen Lauf als Referenzlauf RL zum indirekten Einrichten der Laufachse X-X des Karbiners KB dient. Hierzu ist die Waffenaufnahme WA1 des Sturmgewehrs mit zwei zur Laufachse Z-Z koaxialen Halterungsflächen HF1 und HF2 versehen, die fest entsprechend einer genauen Parallellage der Achsen Z-Z und Y-Y mit Abstand über der Tragplatte TR angebracht sind. Gegebenfalls kann eine nicht dargestellte Richtungs-Justiereinrichtung nach hier vorgesehen werden, beispielsweise in Form einer Höhen- Einstellvorrichtung für eine der genannten Halterungsflächen. Entsprechend zur Laufachse Z-Z koaxiale Zylinderflächen des Sturmgewehrlaufes bzw. einer entsprechenden Schäftung werden mittels Klemmgliedern K3 und K4 in fester Anlage an den Halterungsflächen HF3 und HF2 gehalten.In the manner shown in FIG. 2 and FIG. 4, the weapon holder WH furthermore comprises a receptacle WA 1 for an assault rifle SG, the barrel of which serves as a reference barrel RL for indirectly setting up the barrel axis XX of the carbine KB. For this purpose, the weapon receptacle WA 1 of the assault rifle is provided with two mounting surfaces HF 1 and HF 2 which are coaxial with the barrel axis ZZ and which are fixed at a distance above the support plate TR in accordance with a precise parallel position of the axes ZZ and YY. If necessary, a direction adjustment device (not shown) can be provided here, for example in the form of a height adjustment device for one of the mounting surfaces mentioned. Coaxial cylinders corresponding to the running axis ZZ Surfaces of the assault rifle barrel or a corresponding shaft are held in fixed contact with the mounting surfaces HF 3 and HF 2 by means of clamping members K 3 and K 4 .

Auch der-vergleichsweise geringe-Rückstossimpuls der Sturmgewehres wird am Kolben dieser Waffe durch den Körper einer Bedienungsperson aufgenommen. Ebenso ist die vorgenannte, vollständige oder teilweise Aufnahme durch eine Gegenfederung mit entsprechender Dämpfung möglich. Selbstverständlich dient die Einrichtung nicht nur zur indirekten Richtungsjustierung des Karabiners, sondern auch zum Prüfen des Sturmgewehres selbst.The comparatively low recoil impulse of the assault rifle is also picked up by the body of an operator on the piston of this weapon. Likewise, the aforementioned, complete or partial absorption by a counter-suspension with appropriate damping is possible. Of course, the device is not only used for indirect directional adjustment of the carbine, but also for checking the assault rifle itself.

Das indirekte Einrichten erfolgt durch Schussabgabe mit dem Sturmgewehr und gegebenenfalls durch eine Gesamt-Richtungskorrektur der Schussprüfeinrichtung zum Einstellen des Schussbildes auf das Prüfziel. Sodann wird durch Schussabgabe mit dem Karabiner und Richtungsjustierung eine annähernde Deckung der Schussbilder beider Waffen eingestellt. Es kann dann von einer ausreichenden Parallellage der beiden Laufachsen und damit der Laufachse X-X zur Achse Y-Y ausgegangen werden.Indirect set-up is carried out by firing a shot with the assault rifle and, if necessary, by an overall directional correction of the shot testing device to adjust the shot pattern to the test target. Then, by firing the shot with the carabiner and adjusting the direction, an approximate coverage of the shot patterns of both weapons is set. A sufficient parallel position of the two running axes and thus the running axis X-X to the axis Y-Y can then be assumed.

Wenn die Prüfung des Karabiners eine entsprechende Steuung ergeben hat, so kann mittels eine weiteren Waffenaufnahme WA2 für die funktionsfähige Lauf-Schlosseinheit LSE des Karabiners eine von der Schäftung unabhängige Schussprüfung des Laufes vorgenommen werden. Die Waffenaufnahme WA2 umfasst hierzu eine vordere Abstützung A1 mit Klemmglied Ks, beispielsweise in Form eine Exzenterhebels, sowie eine rückwärtige Abstützung A2 mit einem Stellschrauben-Keilgetriebe als Richtungs-Justiereinrichtung YR1 sowie mit zugehörigem Klemmglied K6. Durch Verschieben des in Fig. 3 angedeuteten, das Schloss hinten abstützenden Keiles KL in Horizontalrichtung nach vorn oder hinten kann das rückwärtige Schlossende angehoben oder abgesenkt werden, wobei das rückwärtige Laufende an der vorderen Abstützung A1 eine entsprechende, geringfügige Schwenkbewegung ausführen kann. Zweckmässig wird hierzu das Klemmglied Ks etwas gelockert. Auf diese Weise lässt sich auch die Lauf-Schlosseinheit mit Hilfe der Referenzlauf-Waffe indirekt in ausreichend genaue Parallellage zur Achse Y-Y einstellen. Sodann liefert das aufgenommene Schussbild Aufschluss darüber, ob die Streuung auf den Lauf selber oder die Halterung in der Schäftung zurückzuführen war.If the inspection of the carabiner has shown a corresponding control, a shot test of the barrel which is independent of the stock can be carried out for the functional barrel lock unit LSE of the carbine by means of a further weapon mount WA 2 . For this purpose, the weapon holder WA 2 comprises a front support A 1 with a clamping member K s , for example in the form of an eccentric lever, and a rear support A 2 with an adjusting screw wedge gear as a direction adjusting device YR 1 and with an associated clamping member K 6 . The rear end of the lock can be raised or lowered by moving the wedge KL indicated in FIG. 3, which supports the lock at the rear, in the horizontal direction toward the front or rear, the rear end of the barrel being able to perform a corresponding, slight pivoting movement on the front support A 1 . For this purpose, the clamping member K s is expediently loosened somewhat. In this way, the barrel lock unit can also be adjusted indirectly with the reference barrel weapon into a sufficiently precise parallel position to the YY axis. The recorded shot then provides information as to whether the scatter was due to the barrel itself or the holder in the stock.
