What is in store AK-74
If you've ever held in the hands of the store from a Kalashnikov, it certainly managed to draw attention to the fact that on its rear side there is some mysterious small holes.

To begin to explain how the shop to the automatic rifle. This thing works is very simple. The plastic (or metal) to the size of the box receptacle has a spring which is held under tension ammunition. When a cartridge is leaving the store, the spring expands and pushes up the rest. Accordingly, the fighter puts cartridges and thus makes the spring is compressed when loading the store. The more rounds invested, the more compressed spring.

Attach the store more ammunition than provided its design just will not work. However, it is easy to invest less. Particularly relevant is a problem in situations where the store gets too hard (mostly new) spring. To the soldiers (especially the inexperienced) do not make any mistakes when arming ammunition, stores make-indicator hole. In normal store AK-74 this hole is only one and it is located on the back side.

The essence of the indicator hole is very simple. If it can not see the cartridge, so the store was not fully staffed. If the visible ammunition - the shop is already full. Here is a simple and effective solution makes it easier (and in some situations, and extend!) Life of a soldier. It is worth mentioning that the different shops is a different number of indicator holes. Moreover - it is not necessarily be holes. Sometimes this whole slots as in a pistol holder. With the development of the market of arms began to come and do the unexpected ways ammunition display. For example, there are clear plastic shopping.
