The Original – the OTs-14 Groza

The OTs-14 Groza (Russian: ОЦ-14 "Гроза", lit. "Thunderstorm") is a Russian bullpup assault rifle developed by V. N. Telesh and U. V. Lebedev and manufactured by TsKIB SOO since 1994. It is based on the AKS-74U platform and utilizes the Kalashnikov mechanism in a compact bullpup configuration. In its main variant, the OTs-14-4A, it fires the 9×39 mm subsonic cartridge, making it particularly quiet and suitable for special operations. The weapon was tested during the Chechen Wars and used by Russian Spetsnaz units. The Groza became known to a wider public primarily through its appearance in popular video games such as PUBG and Escape from Tarkov.

The CaDA Groza OTs-14 building block model faithfully recreates the compact bullpup silhouette with the characteristic rear-set magazine and short barrel using building blocks.

The built-in L-motor and battery box make the CaDA electric rifle model ready to fire – 10 included bolts can be fired in single or continuous fire mode. Requires 6× AA batteries (not included).
