2. There are several types of ak 47 magazines and magazines in
general, they are summarized in the following points:
•Box. It is the most popular of the ak magazines, can be
internal (fixed) or detachable. It stores the cartridges in one
or two column stacks and they have a spring on the bottom
that moves the cartridges to the top in each cycle of the gun.
•Drums. Mostly used for light machine guns. They have
circular chambers that position the cartridges with a spring.
Its design allows larger capacities. This kind is common for ak
47 magazines for sale.
•Casket. It is really a type of box magazine; it is wider than
the common ak mags.
•Pan. It is a special type of drum magazine where the
cartridges are perpendicular to the rotation axis and not
parallel to each other. They are commonly mounted on top of
the gun.

3. •Hopper. It was a Japanese prototype where rifle clips were
stacked in fixed hopper allowing interchanging ammunition
between rifles and machineguns but after all the system
proved unreliable and impractical.
•Tubular. It is usually fixed, it consists in a single or multiple
tubular systems where the cartridges are stored end-to-end
and they are loaded by a spring.
•Rotary. It is a rotor shaped like a star, activated by a spring. It
can be detachable or fixed. They are usually low capacity,
holding ten or less rounds.
•Horizontal. The magazine is parallel to the barrel and the
ammunition is rotated in a right angle before entering the
chamber. The only gun that uses this system is the FN P90.
•Helical. They are an extension of the drum design into a
spiral path which allows for a larger capacity. The downside is
that it demands a complicated mechanism increasing the
probability of a malfunction.
