The OTs-14-4 "Groza-4" (Russian: ОЦ-14-4 "Гроза", lit.'Storm')[1] 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.[2]

The weapon is colloquially known as OC-14 or OTs-14 "Groza".[3] 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.[4][5]

The Groza saw limited use in 1999 in the Second Chechen War, however they quickly fell out of favour and are no longer produced.[2]
