OC-14 "Groza"

The OTs-14 Groza is a Russian bullpup assault-rifle system developed in the 1990s for close-quarters and special-unit roles. It reworked AKS-74U-derived ideas into a compact modular weapon that could be configured as a rifle, suppressed weapon, or rifle-grenade-launcher combination.

The Groza concept emphasized compactness and heavy close-range effect, especially in 9x39 mm configurations using subsonic ammunition. Its bullpup layout reduced overall length, while the modular kit allowed suppressor and grenade-launcher configurations. That made it attractive for urban combat, special police, and internal-security missions.

Groza is more notable as a specialized weapon than as a standard service rifle. Bullpup ergonomics, unusual handling, maintenance complexity, and the availability of simpler AK-family alternatives limited its spread. Its real significance is showing Russian interest in compact integrated weapon systems for special operations rather than mass infantry issue.
