Man-portable nordenfelt gun of the soviet era. It apparently 'fired like a minigun' as the ROF is combined to increase the rate but to be suitable for a soldier to handle, ammo supply was limited being magazine fed. 7.62x39 rounds are used for this weapon.

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 uses 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.
