Absolute garbage
This drum mag is absolute garbage. I shot about 10 rounds before the plastic feed lips split and every round began to stovepipe inside the chamber instead of feeding. I bought two of these. The pictures show what an unfired one looks like compared to the one I shot 13 rounds through. I like the loading lever mechanism, it makes loading much easier. But it’s near instant failure means it’s pure garbage and not worth even trying. Buyer beware.
