I saw a magazine ad for a bright orange Tapco brand AK mag(30 round). It says it has the smoother Buligarian design whatever that means. Im not big on AK-47s or the "Kalish",
.
I recall reading that the orange AK type rifle mags(banana shape) were well made. I think it was in Steven Hunter's novel about a terrorist incident in a large US mall. The "tangos" used surplus 7.62x39mm Warsaw Pact weapons with new design magazines.
