In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the terms described below are terms defined in consideration of functions in the present invention, which may vary according to intentions or customs of users and operators. Therefore, the definition should be made based on the content throughout this specification.

As shown in Figures 1 and 2, the 5.56mm series saptan training simulant 10 according to the present invention is made of the assembly of the warhead 11 and the core 12, and the assembled state is as a whole with live bullets. of the same shape and size.

The warhead 11 is a portion forming the warhead of a live bullet, and while going forward, the sharp pointed portion 11a, the first cylindrical portion 11b and the first cylindrical portion 11b maintaining the same outer diameter as the rear of the sharpened portion 11a ) at the back of the second cylindrical portion 11c formed in a cylindrical shape to maintain a larger outer diameter than the cylindrical portion 11b, and a core assembly groove 11d that is opened toward the rear inside the second cylindrical portion 11c. It is made, these (11a, 11b, 11c) are integral, and the first and second cylindrical parts (11b, 11c) are cylindrical parts with only a difference in outer diameter.

A stepped portion 11e is formed between the sharpened portion 11a and the first cylindrical portion 11b to have the same external appearance as a live bullet.

The warhead 11 of such a configuration is expressed (painted) in a colored preferably blue that is a complementary color to a live bullet so that it can be intuitively identified as a simulated bullet, and is made of plastic that is softer than the chamber so as not to damage the chamber of the firearm when loading. and can be manufactured by injection molding. Complementary colors for distinguishing from live bullets are at least one of the warhead 11 and the core 12 .

That is, in the structure of the warhead 11, most of the simulated bullets 10 appear blue, and since blue is the opposite color to that of the live bullets, both the trainer and the supervisor can check the simulated bullets 10, and conversely, blue in the training process. In this case, since the bullet is not the simulated bullet 10, it is very useful to prevent safety accidents through confirmation.

The core 12 is a part that forms the tail of live bullets, and the core rod 12a that is fitted into the core assembly groove 11d of the warhead 11, and the bullet that is expanded to a larger outer diameter at the rear of the core rod 12a It includes a tail portion (12b), a ball receiving portion (12c) formed on the rear surface of the tail portion (12b).

The core rod 12a is fitted and coupled to the core assembly groove 11d of the warhead 11 and is in the form of a rod having the same outer diameter as a whole along the longitudinal direction, and is formed with an outer diameter larger than the inner diameter of the core assembly groove 11d. It is press-fitted to the assembly groove (11d).

Since the outer diameter of the tail portion 12b is larger than that of the core rod 12a, it forms a ring-shaped jaw between the core rod 12a and the rear end of the second cylindrical portion 11c of the warhead 11 . It functions as an additionally supported stopper, and the circumferential surface includes a ring groove 12d identical to that of a live bullet.

The ball receiving part 12c is to prevent the ball from being damaged by avoiding collision with the ball while allowing the ball to advance normally when the ball advances toward the simulated projectile 10 during percussion training, and is preferably a groove that is opened toward the ball. . The groove-shaped ball accommodating part 12c is formed to a greater depth than the distance the ball advances so that the ball does not collide.

It is also possible to insert a cushioning material such as a sponge or rubber into the hole receiving portion 12c.

Alternatively, the ball receiving portion 12c may be a cushioning material (sponge, rubber, etc.) attached to the rear surface of the tail portion 12b of the core 12 without forming a groove.

The core 12 is made of stainless steel, which is the same as or rigid as the magazine, as a material effective in rust prevention and abrasion prevention when inserting bullets, and its color is preferably silver to distinguish it from the warhead 11 .

The simulated bullet 10 of the present invention has the same appearance as a live bullet, and its weight may be the same as that of a live bullet, a method using the weight of the warhead 11 and the core 12, and the length of the core rod 12a There is a method of securing an empty space inside the core assembly groove 11d by shortening the , and inserting a weight (lead, etc.) into the empty space.

The manufacturing method of the 5.56mm series saptan training simulant for saptan training according to the present invention consists of a warhead and a core manufacturing - a process of assembling a warhead and a core.

The warhead and core manufacturing processes are separate manufacturing processes.

For example, in the warhead manufacturing process, a resin is injected into the cavity of a mold for manufacturing a warhead, and after curing, the warhead is injected and manufactured through demolding. If the resin is a colored resin having the surface color of the warhead, it is manufactured without a separate painting process And if the resin is different from the surface color, a coating process is added.

In the core manufacturing process, casting or the like is used.

The warhead and core assembly process is based on a method of press-fitting the core rod 12a of the core 12 into the core assembly groove 11d of the warhead 11. It is also possible
