Ammunition magazine for firearms

Abstract

An ammunition magazine for firearms for multiple types of cartridges with different calibers comprises a magazine body where a cartridge feeder fitted with a spring is movably arranged, while at least two pairs of opposite guide ribs are arranged on the inner wall of the magazine, namely rear guide ribs and central guide ribs.

AI Technical Summary

Benefits of technology

The patent text describes a new design for a magazine that allows a single magazine to be used for different types of cartridges that have the same length and diameter. The design includes additional guide ribs that improve the strength of the magazine body and allow the cartridge feeder to move freely in the magazine without making direct contact with the inner wall. This results in a more cost-effective and versatile design for magazines.

Problems solved by technology

Due to an unsuitable size of ribs for a certain cartridge type, current types of box magazines can cause 2 kinds of defects:The rib size is too large, which means there is a smaller play between the ribs, resulting in the cartridge getting stuck in the magazine body during loading and unloading.

This may cause that, during the removal of cartridges from the magazine body, the magazine spring is not able to completely push the cartridges to the initial position necessary to feed the cartridge to the cartridge chamber.The rib size is small—the cartridges have a big play in the magazine body after loading, which may lead to an unsuitable position of cartridges in the magazine and a failure to feed them to the cartridge chamber, or also inadvertent falling of cartridges out of the magazine during handling.

A small rib size also causes an unpleasant noise during handling of the loaded cartridge caused by free cartridges hitting the magazine body.

However, these guide ribs are not intended to guide multiple types of cartridges, but to guide the feeder.

A general drawback of these magazines is that they can be created for a single cartridge type only.
