Description

GUNS WITH MULTIPLE MAGAZINES

This invention is about guns with multiple magazines. To be more specific, the invention relates to guns with multiple magazines configured that two magazines are simultaneously loaded on the gun barrel, and these two magazines are furnished to be switched even with a simple operation not only to enable continuous firing of ammunition to be performed stably and conveniently but also to make the change of the type of bullets swiftly even in the case when different type of bullets are loaded.

In recent years, the functions of guns have been significantly improved and designed to allow single shot and continuous shots, but are limited to the bullet quantity contained in the magazine. As a result, the depletion of ammunition becomes faster and the interval to exchange the magazine is shorter in case of continuous shots interval, making a shooter vulnerable during the time it takes to replace the magazine.

Thus, there have been attempts made to utilize two or more magazines to increase the number of loaded ammunition and to replace the magazine quickly. There are MP40/I tied to a dual magazine and Burton 1917 LMR as examples. However, MP40/I has showed many cases of loss of stability, leading to malfunctioning of the gun, because of the attempt to simplify the loading structure. Burton 1917 LMR has had problems with the inconvenience of requiring two layers of magazines loaded as well as with the compatibility with the magazine. The tied-type dual magazine has had a problem that the bullet is exposed to the outside and is contaminated.

In particular, all the guns described above not only accelerate the interval to exchange magazines shorter but also require replacement of the magazine after the depletion of bullets in the magazine. In the end, they only have an effect of having two magazines loaded in the gun and have a problem that two magazines cannot be used consecutively.

In order to solve these problems, this invention has been conceived by the background technology described earlier. The purpose of this invention is to provide the gun with multiple magazines, allowing continuous firing of bullets stably and conveniently as the gun is configured to be simultaneously loaded with two magazines on the gun barrel and to enable the switch of loaded two magazines even with a simple operation.
