Here comes the new episode of GunBusters. You asked for a belt-fed machine gun. Here's one, chambered in 7.62x39. The RPD, Ruchnoy Pulemyot Degtyaryova. We’ve got 11 belts here, each holding 100 rounds. That makes it 1100 in total. Post your comments before the action starts and try predicting how many this one’s going to withstand!
Keep in mind that this machine gun fires from an open bolt. Let's go!
