Description

Sight holder of machine gun

The present invention relates to an apparatus for mounting a scope of a machine gun such as K-4, and more particularly, to a machine gun scope mounting device having improved shooting operability by improving the shape of a mount for a day and night scope.

The 40-mm high-speed grenade K-4 machine gun plays a very important role in various combat activities (search / reconnaissance, ambush, attack / defense operations, etc.) performed by the Army's tactical squad.

Day and night sight PVS-05K, which has been installed and operated with the first electric power since 2007, is installed on top of the K-4 machine gun and developed to allow aiming shooting at daytime as well as at night.

Table 1 shows the equipment characteristics of the machine gun day and night sight PVS-05K, which is used for day and night aiming shooting of K-3, K-4 and K-6 machine guns.

division characteristic Night vision Personnel 800 m, Vehicle 1,200 m Detection method Stray light amplification weight 1.2 kg or less Magnification / Clock 4 times / 10 ° Rated voltage (V) 2 x 3.0 V / AA batteries Battery life 40 hours Mount type K-3, K-4 and K-6

Table 2 shows the characteristics of the scope mounts used for fastening the K-4 machine gun with the day and night scope.

division characteristic Body material AL 6061 weight 800 g or less Fastening method Picatinny rail fastening Elevation Control selection

Day-and-night sighting PVS-05K has better range detection capability than existing sights, and it is compact and lightweight, increasing portability and maneuverability, and allowing 800m of day and night observation and 1,200m of vehicles. It greatly contributes to improving day and night combat.

However, in early 2008, the shooting force was often missed due to the detachment of the scope mount from the gun during the K-4 machine gun continuous shooting in the demand force, and additional difficulties were found in the demand force, which was very inconvenient when removing the sight mount. As a result, improvement activities were conducted to fundamentally establish the analysis and improvement plans for these causes.

Regarding the detachment of the scope mount, as shown in Table 3, the sight of the scope mount was released from the gun during the continuous shooting of the K-4 machine gun equipped with the machine gun day and night scope PVS-05K, which was first deployed in the demand group in 2007. This occurred.

Unit name Reserve Operational Status Remarks 3 divisions 6 3 shots lost after 5 consecutive shots Incidence rate:
42% 7th Division 4 1 shot at 3 consecutive shots 15 divisions 4 2 shots lost after 5 consecutive shots

In addition, with regard to the discomfort in detaching the sight mount, three divisions, etc., complained of inconvenience in detachment, such as having to use a separate dismantling tool since it is very difficult to remove the sight after attaching the sight mount.

As a result of causal analysis of these phenomena, the first factor in the scope of the scope mount detachment during continuous shooting is the interference between the gun combat scale and the scope mount, specifically, the interference between the range control member of the scale and the upper surface of the rail of the scope mount. . The combat scale of the K-4 machine gun is designed to adjust and operate the range of the range between 400 and 1,500 m, but when the combat scale's range control member is between 400 and 800 m, between the scale and the upper surface of the sight mount As the interference was generated, it was confirmed that the sight mount was incompletely mounted and the tightening force was weakened.

The second factor in the sighting of the sight mount is incomplete mounting of the sight mount. The scope and fastening method of the sighting mount and the total period are designed to strongly adhere the rail part of the sighting mount to the mount coupling member of the combat scale guard, but as the scale guard is assembled by welding, the dimension tolerance (general tolerance ± 0.2) is different for each firearm. Due to the large relationship, it was judged to be due to incomplete installation.

In addition, as a result of reviewing the problem of disassembly when removing the sight mount, the reason for this is that the space for the finger rest enough for dismantling the fixed handle of the sight mount is very small (only about 5 to 7 mm). It was judged to be caused by lack of dismantling power.

Accordingly, it is an object of the present invention to provide a machine gun scope mounting apparatus that can prevent the phenomenon of separation of the scope mounting.
