STANAG マガジン
The STANAG magazine concept is only an interface, dimensional, and control (magazine latch, bolt stop, etc.) requirement. Therefore, it not only allows one type of magazine to interface with various weapon systems, but also allows STANAG magazines to be made in various configurations and capacities. The standard STANAG magazines are 20, 30, and 40 round box magazines, but there are many other designs available with capacities ranging from 1 round to 60 and 100 round casket magazines, 90 round snail-drum magazines, and 100 round and 150 round double-drum magazines.
