Description

STANAG magazines used for rifle with interchangeable barrels

The present invention relates to a Stanag magazine used for a replaceable barrel rifle, and more particularly, in using the Starnag magazine filled with a bullet corresponding to the replaced barrel by coupling it to the magazine fitting part of the rifle, the Starnag magazine is the magazine It relates to a Starnag magazine used in a replaceable barrel rifle that can solve problems that cause poor ammunition by moving in a fitting groove unnecessarily.

In general, in a rifle, the hammer strikes the ball connected to the bolt by the action of pulling the trigger, and as the ball strikes the detonator, which is the tail of the bullet bitten in the bolt bundle, the warhead is caused by the explosive force of the gunpowder exploding on the body of the gun. It is fired through the barrel connected to the front, and the bolt bundle and the bolt retreat by the gas pressure generated during the explosion, pulling out the cartridge case and discharging it to the outside.

Then, the bolt bundle moves forward again, and the bullet supplied from the magazine enters the chamber, and the ball connected to the bolt is positioned at the position before the strike, so that the strike action is prepared again by the next trigger triggering action.

These rifles are basic personal hand-held firearms used in the military, and are divided into manual and semi-automatic (automatic/semi-automatic) types according to the firing mechanism.

Most of the existing rifles use a one-piece chamber, in order to withstand tremendous pressure when the gunpowder inside the bullet is fired. For this reason, the chamber is integrally formed, the front of which is connected to a barrel from which bullets are fired, and the rear has a space sized for inserting a bullet.

On the other hand, there are various standards for the ammunition used in these rifles, and among them, the AR-15 rifle mainly used in the Western world is an example of a representative rifle using 5.56mm ammunition, and a representative rifle using 7.62mm ammunition. An example is the AK-47 rifle, which is mainly used in Eastern Europe.

Here, the characteristic of the 5.56mm bullet is that it has a destructive power of 1,775 J, and the weight of the warhead is about 3.6g, so it has excellent accuracy due to low recoil. It has excellent destructive power, but has a relatively low accuracy due to large recoil.

Therefore, in consideration of the characteristics of these bullets, rifles have been improved and used so that bullets of different specifications can be used in one rifle.

For example, if you want to use 7.62mm ammunition on an AR-15 rifle that has a barrel that uses 5.56mm by default, then remove the 5.56mm barrel installed on the AR-15 from the AR-15, By installing a barrel that uses 7.62mm rounds on the AR-15, it is possible to change the AR-15 rifle to a rifle that uses 7.62mm rounds.

On the other hand, the magazine used for the AR-15 rifle is a STANAG (STANdardization AGreement) magazine, which is produced in accordance with the military-related standardization agreement called Stanmac. When it loses, the locking part provided on one side of the Starnag magazine is caught by the magazine removal part provided on one side of the magazine fitting part of the AR-15 rifle and fixed. As the locking part formed on one side of the magazine is separated from the magazine removal part, the Starnag magazine can be removed from the magazine fitting part.

However, conventionally, the barrel of the AR-15 rifle is replaced with a barrel that uses 7.62mm bullets, and the AR-15 rifle is loaded with 30 or more 7.62mm bullets in a Starnag magazine that can hold 7.62mm bullets. When a Starnag magazine filled with 7.62mm bullets is inserted into the magazine insert of When this deflection occurs, there is a problem that the upper end of the Starnag magazine is incorrectly positioned in the chamber, resulting in poor ammunition supply.

Hereinafter, the configuration of the present invention will be described in more detail with reference to the illustrated drawings.

First, the body of the Stanag magazine used in the interchangeable barrel firearm according to the present invention can be largely divided into a first straight part, a curved part, and a second straight part, and each configuration will be described in detail with reference to the illustrated drawings below. decide to do

First, prior to the detailed description of the Starnag magazine, the AR-15 rifle 200 in which such a Starnag magazine is used is an improved rifle that can use bullets of different specifications through the replacement of the barrel.

This AR-15 rifle 200 can be used by assembling in the AR-15 rifle 200 after selecting any one of a barrel that can use 5.56mm bullets and a barrel that can use 7.62mm bullets, and the replacement of the barrel Parts necessary for moving and firing the chamber of the projectile can be replaced together.

And the Starnag magazine is provided with a locking part 116 on one side of the body 100 so that when the Starnag magazine is inserted into the magazine fitting part 210 of the AR-15 rifle 200, the locking part 116 is AR - As it is caught in the magazine removal unit of the AR-15 rifle 200, the Stanag magazine is coupled to the magazine fitting part 210 of the AR-15 rifle 200, and when the magazine removal unit is operated, the locking unit 116 is the magazine removal unit It is possible to remove the Stanag magazine from the magazine fitting 210 of the AR-15 rifle 200 as it is separated from the .

On the other hand, the first straight part 110, which is one component constituting the body 100 of the Stanag magazine,

It is a part having a predetermined length and constituting the upper side of the body 100, and is a part fitted and coupled to the magazine fitting part 210 of the AR-15 rifle 200.

As the first straight part 110 has a locking part 116 formed on the side, when the first straight part 110 is inserted into the magazine fitting part 210 of the AR-15 rifle 200, the locking part 116 is the magazine. While being caught in the magazine removal unit provided in connection with one side of the fitting portion 210, the Stanag magazine may be coupled to the magazine fitting portion 210 of the AR-15 rifle 200.

And, when it is necessary to remove the Stanag magazine from the magazine fitting 210 of the AR-15 rifle 200, if the magazine removal part is operated, the locking part 116 is separated from the magazine removal part, so the magazine fitting part At 210, the Stanag magazine may be removed.

The first straight part 110 is configured in a state in which the front part 111 facing the barrel and the rear part 112 facing the trigger are straight and parallel to each other, and the front part 111 and the rear part 112. The lengths of may be equal to each other, or one may be configured to be longer or shorter than the other.

And the curved part 120, which is another component constituting the body 100 of the Stanag magazine,

As a portion constituting the center of the body 100, it is formed to be curvedly extended to a predetermined length from the above-described first straight portion 110, and is bent while having a predetermined curvature toward the front toward the barrel.

An important feature of the present invention is that the curved portion 120 is formed by abruptly bending, and the end E that meets the rear portion 132 on the bottom surface 133 of the second straight portion 130 to be described later is the first straight line. It is formed by being bent abruptly enough to be positioned in front of the virtual line L extending downward from the front part 111 of the part 110 .

That is, for example, when the bullets are sequentially contacted and filled in the Starnag magazine in which 30 bullets are accommodated, the Starnag magazine is formed by bending while having a certain degree of curve according to the external characteristics of the filled bullets.

Here, in the case of the Starnag magazine filled with 5.56mm bullets, the Starnag magazine is formed by maintaining a straight line and bending a part of the lower section into a gentle curve, and the Starnag magazine filled with 5.56mm bullets is the AR-15 rifle (200). When it is inserted into the magazine fitting part 210 of It does not sag to either side in the state coupled to the part 210 .

However, the barrel of the AR-15 rifle 200 is replaced with a barrel that can be used with 7.62mm bullets, and in the case of the Stanag magazine filled with the 7.62mm bullet used for this, it is in the form of a curved line without a straight part like a banana. When the Starnag magazine filled with 7.62mm bullets is inserted into the magazine fitting 210 of the AR-15 rifle 200, the 7.62mm bullets, which are heavier than the 5.56mm bullets, form a curve inside the Starnag magazine. As it is arranged, the center of gravity moves away from the center of the magazine fitting 210 and moves toward the trigger, and eventually, a phenomenon in which the Starnag magazine sags toward the trigger while coupled to the magazine fitting 210 occurs. Due to the phenomenon, the upper part of the Starnag magazine is located unstable in the chamber, and there is a problem in that the ammunition supply is poor.

Accordingly, the present invention effectively distributes the weight of the 7.62mm bullets filled in the body 100 by rapidly bending the curved part 120 of the Starag magazine body 100 filled with 7.62mm bullets. By locating the center of gravity of the magazine at the center of the magazine fitting 210, it is possible to prevent in advance the problem of feeding problems due to the deflection of the Starnag magazine coupled to the magazine fitting 210.

Here, the curved part 120 of the Stanag magazine filled with 7.62mm bullets will be described in detail through numerical values.

That is, the curvature of the rear part 122 that faces the trigger in the curved part 120 is preferably comprised of about 163 mm to 167 mm, and the curvature of the front part 121 that faces the barrel from the curved part 120 is about 99 mm It is preferably composed of to 103 mm.

This is because in the curved part 120, when the curvature of the rear part 122 and the front part 121 is smaller than 163mm and 99mm, respectively, the curved part 120 is not abrupt and becomes gentle, so the 7.62mm bullet filled inside the Starnag magazine. As the center of gravity of the Starnag magazine is shifted away from the center of the magazine fitting 210 and toward the trigger, deflection occurs after the Starnag magazine is coupled to the magazine fitting of the AR-15 rifle. it falls

And when the curvature of the rear part 122 and the front part 121 in the curved part 120 is configured to be larger than 167mm and 103mm, respectively, the curved part 120 is excessively bent, so the bullet that is raised and lowered inside the Starnag magazine The operation of the spring 140 for pushing the pedestal 150 becomes unstable, and the unstable operation of the spring 140 prevents the 7.62mm bullet from being pushed up normally in the Starnag magazine, and the stability of the ammunition is lowered.

On the other hand, the second straight part 130, which is another component constituting the body 100 of the Starnag magazine,

As a part constituting the lower side of the body 100, it is formed to extend by a predetermined length from the aforementioned curved part 120, and the front part 131 facing the barrel and the rear part 132 facing the trigger are straight and parallel to each other. The length of the front part 131 and the rear part 132 may be the same as each other, or one may be configured to be longer or shorter than the other.

On the other hand, the inside of the body 100 of the Stanag magazine is provided with a spring 140 for pushing up the bullets filled therein to the chamber and the bullet support 150 connected to the spring 140 to seat the bullets, 7.62 When the Stanag magazine filled with mm bullets is coupled to the magazine fitting 210 of the AR-15 rifle 200, the center of gravity of the bullet is moved toward the trigger toward the center of the magazine fitting 210. If the curved part 120 is bent abruptly to move it, the compression force of the spring 140 becomes larger in the curved part 120 section, so the burnt pedestal 150 can be effectively pushed up while maintaining the horizontal without inclination. , At this time, the spring 140 may be configured in a circular cross-section, but may also be configured in a square or rectangular rectangular shape to improve the elastic force to push up the bullet more effectively.

In addition, in order to more effectively prevent sagging in the state where the Starag magazine filled with 7.62mm bullets is coupled to the magazine fitting 210 of the AR-15 rifle 200, the first straight part ( When the projection 115 is formed to protrude from the rear part 112 in 110), the first straight part 110 of the Starnag magazine is inserted into the magazine fitting part 210 of the AR-15 rifle 200. While the anti-skidding protrusion 115 is in contact with the inner surface of the corresponding magazine fitting part 210, the first straight portion 110 is pushed toward the barrel due to the anti-skidding protrusion 115.

Therefore, when the sag occurs in the state that the STANAG magazine filled with 7.62mm bullets is coupled to the magazine fitting part 210 of the AR-15 rifle 200, the first straight part 110 for anti-skidding provided A phenomenon in which the protrusion 115 is supported on the inner surface of the magazine fitting part 210 and the Starnag magazine filled with 7.62mm bullets droops while coupled to the magazine fitting part 210 of the AR-15 rifle 200. can be effectively prevented.

Here, it is preferable that the protrusion 115 for preventing slipping is formed to protrude from the rail part 113 formed in the center of the rear part 112 of the first straight part 110 to both stepped parts 114, respectively, and the protrusion for preventing the slipping. The shape of (115) is preferably configured so that the lower side protrudes more than the upper side is inclined from the upper side to the lower side so as not to cause unnecessary interference when the first straight section 110 is fitted into the magazine fitting section 210.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the described content. Therefore, the scope of the described content does not need to be limited to the described embodiments, and should be defined by the claims and equivalents as well as the claims to be described later.
