Doesn’t it ever jam?
It’s all in how you wind the drum. AK drums rock like that, as long as it’s the Chinese pattern. Much more reliable than Romanian, Russian, etc. I learned on a 1927A1 Thompson, and the short .45 rounds had a tendency to sometimes fall sideways, causing some rather epic jams that took minutes to correct. The longer 7.62x39s are too long to misbehave like that. They take some breaking in, but I haven’t had any type of malfunction in several years now. Not bad for a 75 round AK drum I got for free
