The TKB-059 (Cyrillic: ТКБ-059) was a prototype bullpup assault rifle developed by German A. Korobov, best known for its three barrels, which are in a horizontal arrangement similar to the 19th century Nordenfelt gun. It was designed to fire in rapid salvos by combining the rate of fire of each barrel to increase accuracy and hit probability. Another variant of the TKB-059 was made from AKM-style parts for ease of production, though the weapon had ultimately never entered service. To this day, the TKB-059 prototype can be seen as an exhibit at the Tula state arms museum.


The TKB-059 provided "near minigun" performance but was also to be suitable for a soldier to handle. It uses the 7.62×39mm M43 round but the ammo supply was limited as the weapon is magazine-fed. The TKB-059 still worked, but was also quite hard to control due to the combined recoil force from all three barrels. In addition, cartridge ejection is downwards and positioned behind the magazine area, as the weapon uses a gas/recoil operaton similar to that seen in the AN-94 Abakan. Each barrel of the weapon fired independently of each other, all fed from a tripled 90-round box magazine. It has a high cyclic rate of 1400 to 1800 rounds per minute. The priming handle is on top of the weapon.


The TKB-059 is a development of the experimental Pribor-3B (Cyrillic: прибор-3б) rifle, whose name means '3B Device', with 3B meaning '3 barrels', referring to its three-barreled configuration. The 3B was also developed by Korobov.
