The OTs-02 Kiparis, a Russian special-purpose firearm, was officially commissioned into service in 1976 until 1992 for use by the country's law enforcement agencies.
Here is a realistic passage supporting the sentence:

In 1976, the Soviet Ministry of Internal Affairs announced the adoption of the OTs-02 Kiparis, a specialized firearm designed to counter the rising threat of armed criminal gangs. This compact, semi-automatic carbine was specifically engineered for close-quarters combat, featuring a reduced recoil and integrated suppressor. Throughout the 1980s, the OTs-02 Kiparis proved its effectiveness in high-risk operations, earning a reputation as a reliable and deadly tool in the hands of Russia's law enforcement agencies. Despite its eventual replacement in 1992 by more modern designs, the OTs-02 remains a testament to Soviet ingenuity in firearms development.
