As shown in FIGS. 1 and 2, the gun rail system for the selective mounting of parts according to the present invention is provided with a pair of left-right symmetrical gun rail systems at the lower part of the gun, and is supported for shooting. We want to be able to selectively mount the parts (P) at a desired location.

For example, since a rail does not exist in a general K5 pistol, a gun rail system is set so that predetermined parts (P) can be mounted.

As shown in Fig. 9, the predetermined parts (P) refer to gun accessories such as lights, flashes, sights, lasers, sights, telescopes, dot sights, and optical accessories that can be attached and detached to the rail, and predetermined parts (P) can be optionally customized and installed depending on the situation.

As shown in Fig. 1, each of the firearm rail systems is symmetrical and can be fixedly coupled to the lower surface of the frame (F) of the firearm as a pair of firearm rail systems.

As another embodiment, as shown in Fig. 2, the front part of the firearm rail system consists of a single body and can be fixedly attached to the lower surface of the frame (F) of the firearm, and the rear part is separated or combined with left and right sides, and the rear The part is symmetrical and can be fixedly coupled between the trigger guards (G) of the firearm.

In the case of a gun rail system for selectively mounting parts according to the present invention, as shown in FIGS. 1 and 2 , a rail body unit 100 , a mounting unit 200 and an inserting unit (inserting unit, 300) will be included.

First, in the case of the rail body unit 100, as shown in FIGS. 1 and 2, it is fixedly attached to the lower surface of the frame (F) of the firearm to form a body so that predetermined parts (P) are mounted on the firearm. is a configuration that

A front hole 111 is optionally provided in the front portion of the rail body unit 100, and when the front hole 111 is present, when the bolt nut is fastened to the front hole 111, a pair of rail body units 100 is fixedly coupled, and it is possible to prevent left and right or up and down play of the rail body unit 100 .

As another embodiment, when the front part of the firearm rail system consists of a single body, the front hole 111 may not be provided. Because the front part of the firearm rail system is combined into one body, there is no burden of left-right or up-and-down play.

In the case of the rail body unit 100 of the gun rail system for the selective mounting of parts according to the present invention, as shown in FIGS. 3 and 5, a curving part 110, a side guard part 120 , a sloping unit 130 , a step unit 140 , and a cover wall unit 150 are included.

First, in the case of the curving part 110, as shown in FIGS. 4 and 5, it is disposed on the upper part of the rail body unit 100, and is variable in which the curvature concave upward from the front part to the rear part is continuously changed. By forming a curved surface (variable curve), it is a configuration that selectively accommodates the lower surface of the frame (F) of the firearm.

The curving part 110 forms a variable curved surface or an asymmetric curved surface in which the radius of curvature continuously varies from the front part to the rear part. As shown in FIGS. 4 and 5 , the curvature radius of the front portion is larger than the radius of curvature of the rear portion of the curved portion 110 .

For example, since the radius of curvature decreases from the front portion to the rear portion of the curved portion 110 , the area of the curved surface formed in the rear portion of the curved portion 110 increases. An increase in the area of the rear portion of the curving portion 110 is equivalent to an increase in the range for accommodating the lower surface of the frame F of the firearm. Since the rear portion of the curving portion 110 can support and surround the lower surface of the frame F of the firearm, the frame F of the firearm can be stably seated on the rail body unit 100 .

In addition, as the radius of curvature increases toward the front portion of the curving portion 110 , the area of the curved surface formed in the front portion decreases. This is for mounting the parts under the front end of the rail body unit 100 .

In the case of the side guard part 120, as shown in FIG. 3, it is disposed on the outside of the curving part 110 to form an outward-facing body, and when a predetermined part P is mounted, the predetermined part P ) is configured to form a separation distance so that it is spaced apart from the frame (F) of the firearm.

The side guard part 120 forms a body perpendicular to the axial direction on one side of the curving part 110 to form a separation distance.

At this time, as the separation distance is formed in the side guard unit 120, when a bullet is fired from the firearm, energy is not directly transferred to the predetermined parts P mounted on the rail body unit 100 due to the recoil of the firearm. By not doing so, it is possible to obtain the effect of minimizing the impact applied to the predetermined parts (P).

As another embodiment, in the case of the side guard part 120 , as shown in FIG. 5 , the body perpendicular to the axial direction of the curving part 110 may be discontinuously formed.

A predetermined space 121 may be formed in a portion where the side guard unit 120 is discontinuously formed, and the lower part of the firearm may be seated or closely attached to the predetermined space 121 to add stability, and the frame of the firearm (F) performs the function of helping it to be smoothly fastened.

In the case of the slope part 130, as shown in FIGS. 3 and 5, it is connected to the lower part of the side guard part 120 and forms a predetermined inclination outward so that predetermined parts P are mounted. .

By allowing the predetermined parts (P) to span the predetermined inclination formed on the slope portion 130, the predetermined parts (P) can be stably mounted on the rail body unit 100 .

The step unit 140 is configured to form a step in the rear portion of the curving unit 110 so that the joint between the frame F of the firearm and the trigger guard G is seated.

The step unit 140 forms a predetermined level difference in order to prevent the rail body unit 100 from shaking due to the recoil of the firearm when a bullet is fired from the firearm. At this time, since the step 140 is manufactured in the same shape as the step formed in the rear portion of the frame of the K5 pistol, it is possible to prevent the rail body unit 100 from shaking.

In the case of the step unit 140 , as shown in FIGS. 4 and 5 , a first stair unit 141 and a second stair unit 142 are included.

In the case of the first stair part 141 , as shown in FIG. 4 , a step downward from the rear part of the curving part 110 is formed.

The first stair part 141 vertically descends by forming a predetermined step difference with the rear part of the curved part 110 , and forms a flat surface differently from the curved part 110 .

In the case of the second stair part 142 , as shown in FIG. 4 , a step downward from the first stair part 141 is formed.

The second stair part 142 forms a predetermined step difference with the first stair part 141 to form a flat surface in the shape of an inverted steer.

The step portion 140 has a double step structure due to the step between the curving portion 110 and the first stair portion 141 and the step between the first stair portion 141 and the second stair portion 142 . is formed At this time, the formed double step structure is a structure consistent with the step formed between the frame (F) and the trigger guard (G) of the K5 firearm.

That is, it is possible to provide a K5 pistol customized firearm rail system through the double step structure formed by the first stair part 141 and the second stair part 142 .

In addition, when the K5 pistol and the firearm rail system are combined, the double step structure of the first stair part 141 and the second stair part 142 serves as a catch. For example, when a bullet is fired from a firearm, the firearm is pushed back by action and reaction and as the cartridge is ejected, shaking or vibration may also occur in the firearm rail system mounted on the lower surface of the frame (F) of the firearm. At this time, the firearm rail system can be prevented from being separated from the firearm because movement is restricted through the double step structure and is closely attached to the frame (F) of the firearm as much as possible.

In the case of the cover wall part 150, as shown in FIGS. 3 and 5, it extends to the rear of the side guard part 120 and the slope part 130, and an outer wall for covering one side of the step part 140 is formed. composition that forms

The outer wall of the cover wall part 150 selectively covers a part of the rear part of the frame F of the firearm so that the rail body unit 100 can support the frame F of the firearm.

In addition, the cover wall portion 150 is formed to extend from the side guard portion 120, in this case, the thickness of the cover wall portion 150 is formed to be thicker than the thickness of the side guard portion (120). The inner wall where the cover wall portion 150 and the rear end of the curved portion 110 meet may be formed as a curved surface.

As another embodiment, the cover wall part 150 includes an upstair part 151 on the inner wall of the cover wall part 150 .

In the case of the upstair part 151 , as shown in FIG. 5 , a step structure is formed on the inner wall of the cover wall part 150 .

The upstair part 151 forms a step so that it can be combined with the portion formed at the rear end of the frame F1 of the firearm shown in FIG. 9, so that the firearm rail system can be properly mounted on the firearm. do.

In addition, the upstair part 151 forms a stepped structure on the upper part of the step part 140 to form a multi-step structure together with the first stair part 141 and the second stair part 142, so the K5 pistol It has a structure that matches the step formed at the point where the rear end of the frame (F) of the firearm and the front end of the trigger guard (G) meet, so that it is possible to provide a K5 customized firearm rail system.
