Man-portable nordenfelt gun of soviet origin that apparently 'fired like a minigun' as the ROF is combined to increase its rate, but also to be suitable for a soldier to handle. Ammo supply was limited being magazine fed. This weapon uses standard 7.62x39 rounds.

The Pribor-3B 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 is bound to use a gas/recoil operaton similar to that used in the AN94 Abakan assault rifle currently used by Russian special forces. The Pribor-3B would be more practical as a tripod mounted MG if its possible to make a belt feed device for it.
