Man-portable nordenfelt gun of the Soviet era that apparently provided 'near minigun' performance by combining the ROF but to be suitable for a soldier to handle. It uses the 7.62x39 round but the ammo supply was limited as the weapon is magazine fed.
The Pribor 3B (прибор-3б in Cyrillic) still worked but was also quite hard to control due to the recoil force, Cartridge ejection is downwards BEHIND the magazine area as the weapon uses a gas/recoil operaton similar to that used in the AN94 Abakan assault rifle currently used by Russian special forces. Another variant of the Pribor-3B was made from AKM smilar parts to ease production. The Pribor-3B would be more practical as a tripod mounted machine gun if its possible to make a belt feed device for it.
