The corresponding photos with comments were posted on the channel "Vodogray" on Telegram. The machine gun TKB-521 became the trophies of one of the units of the Defense Forces of Ukraine, which confirms its real use in the troops of the Russian Federation. On this occasion, the Defense Express observers noted that until recently this sample could only be seen in the exposition of the Tula Museum of Weapons.
The development of TKB-521 has been conducted since 1953 in the Tula CCB-14 under the guidance of Nikitin designer. In total, about 1000 copies of tests were produced, but in 1959 it lost to the competition of Kalashnikov's machine gun (PC) and was sent to the warehouse. The main reason for the refusal of the TKB-521 was the long and complex refinement of the structure, as well as the technological complexity of production, which requires high accuracy of manufacturing parts.
Nevertheless, TKB-521 had advantages: better pollination resistance, ease of charge and discharge. However, he was inferior to the PC in reliability at high humidity, and also demanded the use of individual machine -gun tapes incompatible with other samples of Soviet machine guns. By the way, the Ukrainian military, whose hands came to this copy, noted the complexity and impracticality of weapons.
"The reviews are not the best-it is difficult and served, and the very fun is that it is not unified with a regular metal ribbon from the PC, and staffing tapes on TKB-521 are not given," they write. The key difference between TKB-521 is the ammunition system. Unlike the PC, where the cartridge is first removed back and down, and then sent to the cartridge, the TKB-521 is implemented a direct sending of the cartridge directly from the tape.
This required the use of special links and a separate machine gun, not compatible with the ribbons from the machine guns of SGM and RP-46. There is information that experts have added that the Russian military could get TKB-521 without the appropriate tapes, which makes their use problematic. In addition, the pictures of the machine guns are depicted without ammunition, which can indicate logistics difficulties.
