That’s a cool rifle, and there’s an interesting story behind it:
During the Cold War, East Germany had gotten a license to produce the AKM from the Soviets, and subsequently sold many of them on the export market. In fact, East Germany became the third-largest supplier of the AK-47/AKM to the third world after the USSR and China. When the Soviets adopted the new 5.45 M74 cartridge and the AK-74 and began to grant production licenses to their Warsaw Pact satellites, one of the conditions was that they could not export their license-built AK-74s (and cut into Soviet export sales). So this was designed as a work around to that restriction, chambering it for .223 Remington/5.56 NATO ammunition instead of 5.45 (which was actually a wise move long term, as almost no one outside of the Warsaw Pact adopted 5.45 as a standard cartridge).
Of course, events of the late 1980’s quickly put an end to this project as well as to East Germany itself. However, large numbers of the 5.56 Weiger magazines did get produced, and in the 1990s many came into the US, often paired with Romanian-produced 5.56-chambered AK’s known as the WASR-3 or SAR-3.
