This new drum magazine is another product from the new, improved ProMag company, which until recently didn’t have the greatest reputation for producing good quality gear. That’s changed, and the the new ProMag DRM-A9 AK-47 Drum Magazine (7.62x39mm) is a case and point. It’s buttressed with a metal reinforced polymer construction that entails high-strength polymer which has metal reinforcements for the front and rear locking lugs as well as the feed lips. It comes with the ProMag Industries lifetime warranty and a feeding device to assist with loading.
