Summarize this article for a 10 year old
The 5.45 mm subkarabinek wz. 1989 Onyks (polish for: subcarbine wz. 1989 Onyx) is a lightweight Polish short variant of the 5.45 mm wz. 1988 Tantal assault rifle, also based on the AKS-74U. Work on the weapon began in 1989 at the Ośrodek Badawczo-Rozwojowy state research institute in the city of Radom. The weapon’s technical specifications were confirmed that same year. It was not until 1990 that production approval was given for the first prototypes, evaluated the following year in a series of military qualification tests resulting in an order for an initial pre-production batch in 1993, to be manufactured at the Łucznik Arms Factory in Radom.[1]

The carbine was created by a team led by B. Szpaderski and its chief engineers were K. Styczyński and E. Wysocki.[1] The Onyks remained a prototype and has never advanced past the research and development stage. The Onyks was designed to equip airborne infantry, police and military special operations units and vehicle crews.
