Description

[0001] The invention relates to an adapter plate for mounting an attachment on a component of a firearm, and also the component of the firearm, and a mounting assembly comprising the individual elements.

[0002] Various attachments for attaching to firearms are known from the prior art. In particular, sights and optics (collectively referred to as "sights"), such as for instance red dot sights and reflex sights, for mounting on a slide of a pistol are known. The sights can in this case be obtained from a wide variety of manufacturers and therefore often have different shapes or fastening geometries. In order to create the possibility of mounting different sights with different shapes on the slide, the use of adapter plates may be necessary. Different adapter plates allow the possibility of mounting different sights with different shapes on a mounting receptacle of a predetermined form on the slide.

[0003] EP 3669136 B1 and the corresponding US 2019049217 A1 disclose for example an adapter plate which has been received in a depression in the slide in a way in which they complement one another in their form. The adapter plate has on the adapter plate upper side two positioning pins, which are designed to interact with positioning recesses of the attachment. The adapter plate underside and the adapter plate upper side are arranged in relation to one another by an adapter plate thickness, wherein the adapter thickness is thinner than the depth of the depression. The fixing possibility known from EP 3669136 B1 has the disadvantage that in the assembled state the adapter plate has not been received in a fixed manner on the slide, and thus can move. This can cause the positioning recesses of the attachment to be knocked out or the adapter plate to be damaged if shots are fired repeatedly.

[0004] US 2023213315 A1 discloses an adapter plate that is positioned between the attachment and the slide. The attachment is fixed on the slide by means of threaded sleeves positioned on the slide with a form fit and screws that interact with them. The fixing possibility known from US 2023213315 A1 has the disadvantage that the positioning in a transverse direction can only be performed insufficiently. A further disadvantage of this system is that the adapter plate is fastened at the notch of the rear sight, and therefore when this system is used there is no longer a rear sight on the bolt. There is therefore no longer the possibility that, in the event of the red dot system malfunctioning or being damaged, aiming is performed by means of the rear sight and the front sight as an emergency sighting device.

[0005] US 2023011632 A1, US 11300382 B2, US 11280587 B2, US 2022260342 A1, US 11460274 B2, CN 217953276 U, WO 2022184070 A1 and US 9062936 B2 disclose adapter plates that are bolted to the slide. The attachment is fastened on the adapter plate by means of screws. These fastening possibilities have the disadvantage that there is an unfavourable transfer of force between the slide and the attachment. In this case, the acceleration forces occurring when a shot is fired, and thus displacement of the slide, can cause damage to the components.

[0006] The object of the present invention was to overcome the disadvantages of the prior art and to provide an improved fixing possibility for differently designed attachments on a component of a firearm.

[0007] The firearm according to the invention may preferably be a pistol. It may however also be a rifle, carbine, submachine gun, shotgun, etc. Firearms are guns that can be carried and used by one person.

[0008] The component may be the slide of a firearm, in particular of a pistol. The component may be the receiver of a rifle. The component may also be a component which is itself mounted on a further component of the firearm. For example, the component may be a rifle scope which is arranged on the firearm. The component may also be a grenade launcher. Furthermore, it may be provided that the component is coupled to the firearm by means of an interface for mounting on a Picatinny rail, by means of an interface for M-Lok or Key Mod, or similar interfaces.

[0009] This object is achieved by a device according to the claims.

[0010] According to the invention, an adapter plate for mounting an attachment, in particular a sight, on a component of a firearm, in particular on a slide of a pistol, is formed. The adapter plate comprises: + an adapter plate body comprising: an adapter plate underside, wherein the adapter plate underside is designed for butting against the component of the firearm, an adapter plate upper side, wherein the adapter plate upper side is designed for butting against the attachment, wherein the adapter plate underside and the adapter plate upper side are arranged in relation to one another by an adapter plate thickness, an adapter plate lateral surface, wherein the adapter plate lateral surface defines an outer contour of the adapter plate, wherein the adapter plate lateral surface is formed at least in some regions in a way in which it complements the form of a depression contour of a depression in the component of the firearm.

[0011] The adapter plate thickness is greater than a depth of the depression in relation to a depression base area, so that in the fitted state the attachment does not butt against the component. The adapter plate body has a cut-out, wherein the cut-out serves for leading through a fastening screw, wherein the fastening screw can support itself on the attachment and can have been screwed into a fastening thread of the component of the firearm.

[0012] In the specific embodiment of a pistol, the adapter plate may be designed for mounting a sight on the slide of the pistol. The adapter plate comprises: + an adapter plate body comprising: an adapter plate underside, wherein the adapter plate underside is designed for butting against the slide, an adapter plate upper side, wherein the adapter plate upper side is designed for butting against the sight, wherein at least one positioning pin, which is designed for interaction with at least one positioning recess of the sight, is arranged on the adapter plate upper side, wherein the adapter plate underside and the adapter plate upper side are arranged in relation to one another by an adapter plate thickness, an adapter plate lateral surface, wherein the adapter plate lateral surface defines an outer contour of the adapter plate, wherein the adapter plate lateral surface is formed in a way in which it complements the form of a depression contour of a depression in the slide.

[0013] The adapter plate thickness is greater than a depth of the depression in relation to a depression base area, so that in the fitted state the sight does not butt against the slide. The adapter plate body has a cut-out, wherein the cut-out serves for leading through a fastening screw, wherein the fastening screw can support itself on the attachment and can be screwed into a fastening thread of the slide.

[0014] The adapter plate according to the invention has the advantage that in the mounted state the attachment does not butt against the component of the firearm, but is just clamped between the adapter plate and the fastening screws. This allows the positioning accuracy of the attachment on the component to be increased. In addition, the risk of damage to the adapter plate or the component and the attachment can be reduced by the design according to the invention. In particular, the service life of the individual components can be increased by the design according to the invention.

[0015] Furthermore, it may be expedient if at least in some portions a separating layer is formed on the adapter plate upper side, adjoining the adapter plate lateral surface, wherein the separating layer extends at least in some regions beyond the limits of the adapter plate lateral surface. A separating layer has the advantage that this measure can be used to ensure that the attachment and the component do not touch one another. If the attachment is for example formed from an aluminium material and the component is formed from an iron material, this could cause corrosion if they touch. This can be prevented by the adapter plate according to the invention or by the separating layer. In addition, the separating layer can be used to achieve the effect that in the fitted state there is no gap between the attachment and the component, thereby reducing the extent of any accumulations of dirt between the attachment and the component. Furthermore, the separating layer may serve to increase the frictional engagement between the adapter plate and an attachment. In addition, by means of the separating layer, a battery compartment, which is arranged on an underside of the attachment, can be further sealed from the environment. The battery can thus be additionally protected from water and moisture ingress.

[0016] In particular, it may be provided that the adapter plate body and / or the separating layer are formed from an electrically non-conductive material.

[0017] It may also be provided that the adapter plate body and the separating layer are formed from a different material. This has the advantage that the separating layer can be formed from an elastic material, such as for instance a silicone-like material.

[0018] In an alternative embodiment variant, it may be provided that the separating layer is produced as one part with the adapter plate body. In particular, it may be provided in this case that the separating layer and the adapter plate body are formed as a one-part injection moulding.

[0019] Furthermore, it may be provided that the adapter plate body is formed from a two-component material.

[0020] In addition, it may be provided that the separating layer has been adhesively bonded onto the adapter plate body.

[0021] Furthermore, it may be provided that the adapter plate is formed as a milled part from a plastic or from a metal.

[0022] Furthermore, it may be provided that the adapter plate is formed by 3D printing.

[0023] Furthermore, it may be provided that the separating layer has a separating layer thickness. In particular, it may be provided that the separating layer thickness is between 0.1 mm and 2 mm, in particular between 0.5 mm and 1.5 mm, preferably between 0.8 mm and 1.2 mm.

[0024] Furthermore, it may be provided that the adapter plate thickness is between 1 mm and 10 mm, in particular between 2 mm and 5 mm, preferably between 2.5 mm and 3.5 mm.

[0025] Furthermore, it may be provided that the separating layer thickness is between 10% and 50%, in particular between 20% and 40%, preferably between 25% and 35%, of the adapter plate thickness.

[0026] In particular, it may be provided that the separating layer has a separating layer thickness, wherein the separating layer thickness is between 0.1 mm and 2 mm, in particular between 0.5 mm and 1.5 mm, preferably between 0.8 mm and 1.2 mm, or between 10% and 50%, in particular between 20% and 40%, preferably between 25% and 35%, of an adapter plate thickness, wherein the adapter plate thickness is between 1 mm and 10 mm, in particular between 2 mm and 5 mm, preferably between 2.5 mm and 3.5 mm. An adapter plate with such a dimensioning is particularly suitable.

[0027] In addition, it may be provided that the adapter plate body is formed from a plastics material, in particular as an injection moulded part. This has the advantage that an adapter plate body produced in this way can be produced in series production with a high repeat accuracy. In addition, an adapter plate body produced in this way can act as an electrical insulator between the attachment and the component, whereby the susceptibility to corrosion can be reduced.

[0028] Furthermore, it may be provided that at least one positioning pin, which is designed for interaction with at least one positioning recess of the attachment, is arranged on the adapter plate upper side. In particular, it may be provided that two positioning pins are arranged on the adapter plate upper side. Furthermore, it may be provided that three or more positioning pins are arranged on the adapter plate upper side. The positioning pins have the advantage that the attachment can be positioned relative to the adapter plate by means of the positioning pins. In addition, a force acting in the longitudinal or transverse direction can be transferred from the attachment into the adapter plate by means of the positioning pins. For example, the force occurring during firing or the force released by the recoil can thus be transferred.

[0029] Furthermore, it may be provided that the adapter plate has a first cut-out and a second cut-out. Furthermore, it may be provided that a front main region is formed on the adapter plate in front of the cut-outs when viewed in the longitudinal direction. A rear main region may be formed behind the cut-outs when viewed in the longitudinal direction. The front main region may have a width. The rear main region may have a width. The width of the front main region may be the same size as the width of the rear main region.

[0030] Furthermore, it may be provided that the adapter plate has in the region of the at least one cut-out a cut-out width which is between 20% and 80%, in particular between 30% and 60%, preferably between 40% and 55%, of the width of the front main region, and corresponds to the narrowing width. This has the advantage that this measure allows a particularly good form-fitting connection between the cut-out and the adapter plate to be achieved.

[0031] Furthermore, it may be provided that the front main region adjoins the head region of the adapter plate.

[0032] According to the invention, a component of a firearm, in particular a slide of a pistol, is provided. The component comprises: a depression with a depression contour for receiving an adapter plate for an attachment, in particular a sight, or for directly receiving the attachment, wherein the depression has a depth in relation to a depression base area; a fastening thread.

[0033] The depression contour extends forwards and backwards beyond the fastening threads with respect to a longitudinal direction. The fastening thread serves for screwing in a fastening screw which has been received directly in the attachment. In other words, it may be provided that an imaginary connecting line between the first fastening thread and the second fastening thread intersects the depression contour or overlaps with the depression contour. The depression contour may be arranged between the first fastening thread and the second fastening thread in the transverse direction.

[0034] The component according to the invention has the advantage that in the mounted state the attachment is clamped between the adapter plate and the fastening screws only and it does not butt against the component of the firearm. This allows the positioning accuracy of the attachment on the component to be increased. In addition, the risk of damage to the adapter plate or the component and the attachment can be reduced by the design according to the invention. In particular, the service life of the individual components can be increased by the design according to the invention.

[0035] According to a development, it is possible that the depression base area is arranged at a distance from a component outer surface. This has the advantage that this measure allows the attachment to be better integrated into the component, so that the attachment protrudes less from the component. In particular, this is advantageous if the attachment is a sight device, since this measure allows the visual axis and the barrel bore axis to be arranged closer to one another.

[0036] Further, it may be expedient if, when seen in plan view, the depression contour has a narrowing, wherein the narrowing is formed in the region of the fastening threads and wherein the fastening threads extend from the depression base area. This has the advantage that this measure allows the fastening threads to be easily positioned in the component. In addition, the narrowing can be used to create a shape contour by which the adapter plate can only be joined to the component in one position. In particular, it may be provided that the narrowing has a reduced width. When seen in plan view, the narrowing may be formed as a constriction.

[0037] Furthermore, it may be provided that the narrowing is formed on at least one side of the adapter plate when viewed in the longitudinal direction. In particular, it may be provided that the narrowing is formed on two sides of the adapter plate when viewed in the longitudinal direction. The narrowing may be formed as a constriction in the transverse direction.

[0038] Furthermore, it may be provided that at least two fastening threads, preferably four fastening threads, are formed, in particular that the fastening threads are arranged in pairs opposite one another in the component. This has the advantage that arranging the fastening threads in pairs allows a uniform distribution of force over the adapter plate to be achieved by means of the screwed-in screws.

[0039] Furthermore, it may be provided that at the depression a front main region is formed in front of the narrowing when viewed in the longitudinal direction, wherein the front main region has a width, wherein the narrowing has a narrowing width, wherein the narrowing width is between 20% and 80%, in particular between 30% and 60%, preferably between 40% and 55%, of the width of the front main region. This has the advantage of providing a good force-transferring capability.

[0040] Furthermore, it may be provided that at the depression a front main region is formed in front of the narrowing when viewed in the longitudinal direction. A rear main region may be formed behind the narrowing when viewed in the longitudinal direction. The front main region may have a width. The rear main region may have a width. The width of the front main region may be the same size as the width of the rear main region.

[0041] Furthermore, it may be provided that the front main region adjoins the depression head.

[0042] The invention also relates to a mounting assembly comprising an attachment, in particular a sight; a component of a firearm, in particular a slide of a pistol; an adapter plate for mounting the attachment on the component, the adapter plate comprising: + an adapter plate body comprising: an adapter plate underside, wherein the adapter plate underside butts against the component of the firearm, an adapter plate upper side, wherein the adapter plate upper side butts against the attachment, wherein at least one positioning pin, which interacts with at least one positioning recess of the attachment, is arranged on the adapter plate upper side, wherein the adapter plate underside and the adapter plate upper side are arranged in relation to one another by an adapter plate thickness, an adapter plate lateral surface, wherein the adapter plate lateral surface defines an outer contour of the adapter plate, wherein the adapter plate lateral surface is formed in a way in which it complements the form of a depression contour of a depression in the component of the firearm.

[0043] The adapter plate thickness is greater than a depth of the depression in relation to a depression base area, so that the attachment does not butt against the component. The adapter plate body has a cut-out, wherein the cut-out serves for leading through a fastening screw, wherein the fastening screw supports itself on the attachment and has been screwed into a fastening thread of the component of the firearm.

[0044] The mounting assembly can also be referred to as a mounting system.

[0045] The mounting assembly according to the invention has the advantage that in the mounted state the attachment is clamped between the adapter plate and the fastening screws only and does not butt against the component of the firearm. This allows the positioning accuracy of the attachment on the component to be increased. In addition, the risk of damage to the adapter plate or the component and the attachment can be reduced by the design according to the invention. In particular, the service life of the individual components can be increased by the design according to the invention. Furthermore, material-related corrosion between the component and the attachment can be reduced by the features according to the invention.

[0046] Furthermore, it may be expedient that the adapter plate body has a head region, wherein the head region has a head width in the transverse direction, wherein the component has a component width, wherein the head width is between 95% and 105%, in particular between 98% and 102%, preferably between 99% and 101%, of the component width. This has the advantage that this measure allows the adapter plate body to be easily gripped for detachment from the component.

[0047] It may also be provided that the positioning pin is arranged in the head region. This has the advantage that the positioning pins arranged in the head region can bring about good positioning accuracy.

[0048] In addition, it may be provided that the adapter plate body has opposite from the head region in the longitudinal direction a recess in the region of the adapter plate upper side, wherein the depression contour has a holding lug corresponding to the recess. This has the advantage that the adapter plate body can be additionally secured in the component by means of the recess or the holding lug.

[0049] Also advantageous is a configuration according to which it may be provided that the adapter plate body has in the head region a projection on the adapter plate upper side, wherein the attachment butts against the projection. This has the advantage that the projection allows the forces that occur when a shot is fired to be transferred from the component to the attachment without the fastening screws thereby being subjected to excessive stress.

[0050] Furthermore, it may be provided that the adapter plate upper side has a first coefficient of friction in relation to the attachment and that the component outer surface has a second coefficient of friction in relation to the attachment, wherein the first coefficient of friction is greater than the second coefficient of friction. This has the advantage that this measure allows the forces which occur for example when a shot is fired due to the mass inertia to be transferred better between the component and the attachment. This allows the service life of the individual components to be increased.

[0051] Furthermore, it may be provided that the adapter plate upper side has a first coefficient of friction between 0.1 and 1, in particular between 0.15 and 0.8, preferably between 0.2 and 0.5, in relation to the attachment. This has the advantage that this measure allows the forces which occur for example when a shot is fired due to the mass inertia to be transferred better between the component and the attachment. This allows the service life of the individual components to be increased.

[0052] Furthermore, it may be provided that the adapter plate body extends with respect to the longitudinal direction over the complete extent of the attachment. This has the advantage that the attachment can rest over its full surface area on the adapter plate.

[0053] The invention also relates to a mounting assembly comprising an attachment, in particular a sight; a component of a firearm, in particular a slide of a pistol, the component comprising: a depression with a depression contour for directly receiving the attachment, wherein the depression has a depth in relation to a depression base area, a fastening thread, wherein the depression contour extends with respect to a longitudinal direction to beyond the fastening threads and a fastening screw received directly in the attachment has been screwed into the fastening thread, wherein the attachment butts against the component of the firearm, wherein a connection contour is formed on an underside of the attachment, wherein the connection contour is formed in a way in which it complements the form of the depression contour of the depression in the component of the firearm.

[0054] The mounting assembly according to the invention has the advantage that in the mounted state the attachment does not butt against the component of the firearm, but is just clamped between the adapter plate and the fastening screws. This allows the positioning accuracy of the attachment on the component to be increased. In addition, the risk of damage to the adapter plate or the component and the attachment can be reduced by the design according to the invention. In particular, the service life of the individual components can be increased by the design according to the invention.

[0055] Furthermore, it may be provided that a cover plate is formed, being designed in a form and function that complement the depression in the component, in particular in the slide. The cover plate may complete the outer contour of the component, in particular the slide, so that, when the cover plate is inserted, the impression is created that the depression in the component is not visible. This makes it easy to remove the adapter plate and the attachment when they are not in use.

[0056] Furthermore, it may be provided that a cover plate is formed, being designed at least partially in a form and function that complement the depression in the component, in particular in the slide. It may be provided for example that only at least a part of the lateral surface area of the adapter plate is designed in a form and function that complement at least a part of the depression contour of the depression in the component of the firearm.

[0057] Of course it is also conceivable that the cover plate interacts with the adapter plate when it is inserted. In this case, the cover plate can serve as a replacement for the attachment.

[0058] For the purposes of this document, being of a complementary form means that the adapter plate lateral surface is adapted in its contour to a depression contour of a depression in the component of the firearm.

[0059] For better understanding of the invention, it is explained in more detail with reference to the following figures.

[0060] They respectively show in a greatly simplified, schematic representation: Fig. 1a perspective exploded representation of a first exemplary embodiment of a firearm in the form of a pistol; Fig. 2a second exemplary embodiment of an adapter plate in a perspective view; Fig. 3a third exemplary embodiment of an adapter plate and a slide of the pistol in a perspective exploded representation; Fig. 4a fourth exemplary embodiment of an adapter plate; Fig. 5a perspective exploded representation of a fifth exemplary embodiment of a firearm in the form of a pistol; Fig. 6a fifth exemplary embodiment of the adapter plate in a perspective representation; Fig. 7further exemplary embodiments of the adapter plate.

[0061] As an introduction, it should be noted that in the differently described embodiments the same parts are provided with the same reference numerals or the same component designations, it being possible for the disclosures contained throughout the description to be applied analogously to the same parts with the same reference numerals or the same component designations. Also the positional indications chosen in the description, such as for example top, bottom, side, etc., refer to the figure directly being described or shown, and these positional indications can be transferred analogously to the new position in the case of a change in position.

[0062] Fig. 1 shows a perspective view of an exploded representation of a first exemplary embodiment of a firearm 1 in the example of a pistol 2.

[0063] As can be seen from Fig. 1, it may be provided that the firearm 1 comprises a slide assembly 3. Furthermore, it may be provided that the firearm 1 comprises a frame assembly 4. In the representation according to Fig. 1, the slide assembly 3 is mounted on the frame assembly 4.

[0064] It may be provided in particular that in the state of use of the firearm 1 the slide assembly 3 is coupled to the frame assembly 4.

[0065] The slide assembly 3 may comprise a slide 6. The slide 6 may be a component 7 of the firearm 1. In a further embodiment variant, the component 7 of the firearm 1 may also be formed by the frame 5.

[0066] In embodiment variants that are not shown, it is also conceivable that the firearm 1 is designed as a long weapon and the component 7 is a component of the long weapon.

[0067] The positional indications chosen in the description, such as for example top, bottom, side, etc., refer to the position of the firearm 1 shown in Fig. 1. This position may also be referred to as the position of use. In this case, front or a front side is on the left side of Fig. 1, and consequently on the side of the muzzle opening of a barrel of the firearm 1. Rear or a rear side is correspondingly on the side opposite from the muzzle opening of the barrel. The underside is at the bottom and an upper side is at the top. A transverse extent or transverse direction 8 extends in the width of the firearm 1 transversely to the longitudinal direction 9. A vertical extent or vertical direction 10 extends from top to bottom.

[0068] As can be further seen from Fig. 1, it may be provided that an attachment 11 which serves for mounting on the firearm 1 is formed. It may be provided in particular that the attachment 11 is designed as a sight 12. Such a sight 12 may be for example a red dot sight. Furthermore, it is also conceivable that the attachment 11 is designed as a laser sight. Furthermore, it is also conceivable that the attachment 11 is designed as a tactical light. The attachment 11 may of course also be designed as some other removable component.

[0069] The further description of the figure is with reference to the embodiment of the sight 12, which can be mounted on the slide 6. This embodiment relates specifically to the pistol 2. At this point it is pointed out once again that all the execution details described in this document can also be applied mutatis mutandis to other components 7 of firearms 1 and other attachments 11.

[0070] As can be further seen from Fig. 1, it may be provided that the sight 12 is fastened on the slide 6 by means of an adapter plate 13. The adapter plate 13 serves for allowing different sights 12 with different shapes or different connection geometries to be fastened on the slide 6. The assembly of the slide 6, the sight 12, and the intermediate adapter plate 13 can be referred to as mounting assembly 14.

[0071] In a further embodiment variant, it is also conceivable that the sight 12 is directly adapted to the shape of the slide 6, and thus the adapter plate 13 is not necessary. The mounting assembly 14 consists in this case only of the sight 12 and the slide 6.

[0072] As can be seen from Fig. 1, it may be provided that on a component outer surface 15, which is formed by the upper side of the slide 6, there is formed a sight receptacle 16, which serves for receiving the adapter plate 13 or the sight 12. In particular, it may be provided that the sight receptacle 16 has a depression 17, which may extend downwards in the vertical direction 10 from a depression base area 18. The depression base area 18 itself may in this case already be arranged at a distance 19 from the component outer surface 15. In other words, the depression base area 18 may already form a recess in relation to the component outer surface 15. This has the advantage that this measure allows the sight 12 to be accommodated in this recess, and thus allows it to be arranged as close as possible to the barrel with respect to the vertical direction 10. The closer the sight 12 can be arranged to the barrel, the smaller the distance between the visual axis of the sight 12 and the bore axis of the barrel can be. Thus, it is easier to align the visual axis with the projectile trajectory for a certain distance. This allows the accuracy of the firearm 1 to be improved.

[0073] In particular, it may be provided that the depression base area 18 is designed as a flat area which is arranged parallel to the component outer surface 15.

[0074] Furthermore, it may be provided that the depression 17 has a depression contour 20. In particular, it may be provided that the depression 17 extends between a depression bottom 21 and the depression base area 18. The distance between the depression base area 18 and the depression bottom 21 can be referred to as the depth 22 of the depression 17.

[0075] As can be further seen from Fig. 1, it may be provided that the depression 17 extends over the complete component width 23 in the region of a depression head 24. The depression 17 can thus lead into a side area 25 or into both side areas 25 of the slide 6.

[0076] Furthermore, it may be provided that a first fastening thread 26 is arranged in the depression base area 18. In addition, it may be provided that a second fastening thread 27 is arranged in the depression base area 18. The first fastening thread 26 and the second fastening thread 27 may be arranged laterally in relation to the depression 17. In particular, it may be provided that the depression 17 has a narrowing 28 in the region of the first fastening thread 26 or in the region of the second fastening thread 27. The two fastening threads 26, 27 arranged laterally opposite and thus in pairs can also be referred to as a pair of fastening threads.

[0077] Furthermore, it may be provided that a third fastening thread 29 is formed in the region of the first fastening thread 26 or adjacent thereto. Furthermore, it may be provided that a fourth fastening thread 30 is formed in the region of the second fastening thread 27 or adjacent thereto. The third fastening thread 29 and the fourth fastening thread 30 may be arranged in pairs and closer together than the first fastening thread 26 and the second fastening thread 27. In particular, it may be provided that the first fastening thread 26 and the second fastening thread 27 serve for fastening a first type of a sight 12 and the third fastening thread 29 and the fourth fastening thread 30 serve for fastening a second type of the sight 12.

[0078] Furthermore, it is of course also conceivable that only the first fastening thread 26 is provided.

[0079] Furthermore, it is of course also conceivable that, in addition to the first fastening thread 26, the second fastening thread 27, the third fastening thread 29 and the fourth fastening thread 30, further fastening threads are provided to allow further types of sights 12 to be fastened.
