The [[5.45×39mm|5.45 mm]] '''subkarabinek wz. 1989 Onyks''' ([[Polish language|polish]] for: sub[[carbine]] wz. 1989 Onyx) is a lightweight Polish short variant of the 5.45&nbsp;mm [[Kbk wz. 1988 Tantal|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.<ref name="woźniak197">Woźniak, Ryszard. Encyklopedia najnowszej broni palnej - tom 3 M-P. Bellona. 2002. p.197</ref>

The carbine was created by a team led by B. Szpaderski and its chief engineers were K. Styczyński and E. Wysocki.<ref name="woźniak197"/> 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.

==Design details==
The carbine has an identical design layout, system of operation, locking mechanism and uses the same type of ammunition as the Tantal rifle, and the main modifications include the following components: the barrel, bolt carrier and piston rod, gas cylinder, foregrip, heatguard, muzzle device and [[iron sight]]s.

Compared to the Tantal, the Onyks features a barrel reduced in length by {{convert|216|mm|abbr=on|1}}, fitted with a different type of muzzle device. Due to the barrel's length, this device is primarily used to reduce muzzle flash, but it can also be used to mount and launch [[rifle grenade]]s. At its muzzle end, the device has a conical [[Flash suppressor|flash hider]], and on its tapered, external surface – a retainer spring and two collars, used to attach and guide rifle grenades.

The Onyks features a bolt carrier borrowed from the wz. 1988 rifle, but with a significantly shortened gas piston rod.<ref name="woźniak197"/> Additionally both the gas cylinder and upper heatguard have been reduced to accommodate the short gas system.

The carbine also has a different sighting arrangement than the Tantal rifle, with a newly designed rear sight. The open-type flip sight with both 100-200 and 400 m settings is installed at the rear of an extended sight rail protected by ears, which is riveted to the rear sight base. The sight has two settings, “1 i 2” and “4” (that correspond to firing ranges from 100 to 200&nbsp;m and 400&nbsp;m respectively).<ref name="woźniak198">Woźniak, Ryszard. Encyklopedia najnowszej broni palnej – tom 3 M-P. Bellona. 2002. p.198</ref> The flip sight locks in position with a spring detent. The adjustable front sight post is screwed into the front sight base that is installed in the gas block. The Onyks can be fitted with [[tritium]] night sights, similar to those used in the wz. 88 Tantal. Recesses cut into both sides of the sight rail are used to mount optical sights.

The wooden or synthetic handguard, designed specifically for the Onyks is installed in a way analogous to the Tantal rifle's handguard.

The carbine is supplied with three spare magazines, four 15-round stripper clips and a magazine guide, cleaning kit, cleaning rod (which is stored in the maintenance kit, unlike the Tantal – under the barrel), sling, accessory pouch and oil bottle. Also unlike the Tantal, the Onyks is not compatible with a [[bayonet]], [[bipod]] or the [[40 mm]] [[Pallad grenade launcher|wz. 1974]] underslung [[grenade launcher]].<ref name="woźniak198"/>
