The Pioneer Arms Hellpup is a compact AK-pattern pistol manufactured in Radom, Poland, by Pioneer Arms Corp (PAC), introduced as an affordable, civilian-legal alternative based on AKM/AKMS designs. Produced since the early 2000s, it gained notoriety for initially using cast trunnions before switching to forged parts, offering a lightweight, short-barreled option chambered in 7.62x39mm.
