Notes
The weapon was produced in limited quantities by converting existing AKS-74U rifles. Several hundred Groza kits were manufactured. The MVD initially only procured the 9x39mm Groza-4 variant; the 7.62x39mm Groza-1 was manufactured later after additional clients were found. Both variants saw combat use during the Chechen conflicts in the mid-to-late 1990s. The Groza remains in some Russian police armories but is rarely used today, having been largely supplanted by more modern designs. The loaded weight of 4.0 kg includes the grenade launcher assembly.
Background
The Groza earned its 'Thunderstorm' nickname from its formidable appearance combining a compact bullpup rifle with an underslung grenade launcher into a single package shorter than a standard AK-74. Despite its innovative modular design, the Groza never achieved widespread adoption, partly because the subsonic 9x39mm AS Val and VSS Vintorez already filled the suppressed special operations role more elegantly.
