The TKB-0111 (Cyrillic: ТКБ-0111) is a prototype Soviet assault rifle designed by somewhat famed firearms designer German Korobov. It is known for being one of the participants in the Abakan trials as a contender to replace the AK-74 assault rifle in service.
The TKB-0111 was one of the original eight contenders in the Abakan trials, competing with others like Postnikov's APT and Stechkin's TKB-0146 as a potential weapon to replace the AK-74 in service. Unfortunately for Korobov, his design was eliminated right off the bat along with Postnikov's APT; the reason for the TKB-0111's elimination was that it was deemed the least promising weapon, and the TKB-0111 faded into history.
The TKB-0111 is another one of those weird and wacky designs by German Korobov of TKB-059 fame. The TKB-0111 had a distinctive, large muzzle brake and a particularly high rate of fire in burst mode, but this would prove detrimental as the TKB-0111 would burn ammo up quickly in real combat situations.
