TKB-059 (ТКБ-059) was a Soviet three-barrel bullpup assault rifle, capable of fully automatic fire, chambered for the 7.62×39mm round and manufactured by Tula Arms Plant in 1966. It was based on the Device 3B (Прибор 3Б), an earlier experimental assault rifle that also had three barrels.^[3] Both weapons were developed by the small arms designer German Aleksandrovich Korobov.

Both the TKB-059 and the Device 3B used a specialized 7.62×39mm magazine with three columns, akin to three individual box magazines placed and attached side by side. There were two sizes of magazine: one with a total capacity of 45 rounds (15 rounds per column), and one with a capacity of 60 rounds (20 rounds per column). Each barrel was independently fed from its corresponding column.^[1] The TKB-059 could be fired ambidextrously as the spent cartridge casings ejected downwards behind the magazines.^{[citation needed]}

The TKB-059 prototype can now be seen at the Tula arms museum.^[4]

The "Chaingun Cannon" in Duke Nukem 3D is based on the TKB-059, but having a different design.

The weapon is featured in Payday 2 as the Rodion 3B Rifle.
