OTs-14 Groza
Produced by TsKIB SOO
The OTs-14-4 "Groza-4" (Russian: ОЦ-14-4 "Гроза", lit. 'Storm') is a Russian selective fire bullpup assault rifle chambered for the 9×39mm subsonic cartridge. It was developed in the 1990s at the TsKIB SOO (Central Design and Research Bureau of Sporting and Hunting Arms) in Tula, Russia. The weapon is colloquially known as OC-14 or OTs-14 "Groza". The OTs-14-4A "Groza-4" has one derivative, the TKB-0239 (ТКБ-0239), also known as OTs-14-1A "Groza-1", chambered for the 7.62×39mm cartridge. The Groza saw limited use in the Second Chechen War and Russo-Georgian War. However OTs-14 Groza are still used by some police force across Russia.
