Ak 47 magazines and its components

There are several types of ak 47 magazines and magazines generally speaking, they are summarized in the following points:

• Box.  It is easily the most popular of the ak magazines, may be internal (fixed) or detachable.  It stores the cartridges in one or two column stacks and they've a spring on the bottom that moves the cartridges up in each cycle of the gun.
• Drums.  Mostly used for light machine guns.  They have circular chambers that position the cartridges using a spring.  Its design allows larger capacities.  This kind is normal for ak 47 magazines for sale.
• Casket.  It is really a type of box magazine; it really is wider compared to common ak mags.
• Hopper.  It was obviously a Japanese prototype where rifle clips were stacked in fixed hopper allowing interchanging ammunition between rifles and machineguns but all things considered the system proved unreliable and impractical.
• Pan.  It can be a special kind of drum magazine in which the cartridges are perpendicular to the rotation axis and never parallel together.  They are commonly installed on top of the gun.
• Tubular.  It is usually fixed, it consists within a or multiple tubular systems in which the cartridges are stored end-to-end and they are loaded with a spring.
• Rotary.  It is really a rotor in the shape of a star, activated by a spring.  It could be detachable or fixed.  They are often low capacity, holding ten or less rounds.
• Horizontal.  The magazine is parallel to the barrel and the ammunition is rotated in the right angle before entering the chamber.  The only gun which uses this system may be the FN P90.
• Helical.  They are extra time of the drum design into a spiral path that allows for a larger capacity.  The bad thing is that it demands an intricate mechanism increasing the probability of a malfunction.
