History:
Onyks was developed together with the Tantal rifle as a compact weapon better suited for certain types of use. Onyks was made in two different chambering's: 5.45x39mm and 5.56mm NATO.


Description:
The Onyks is externally very similar to the Russian AK-74U (by some sources called AKR). It is a gas operated, selective-fire carbine. The receiver is made of sheet metal stampings and as the one in its bigger brother houses a new trigger mechanism with separated safety and selector lever. The muzzle device has been modified to allow it to be used for grenade launching (the prototype, however, had a muzzle brake identical to the Russian gun). The rear sight is another clear difference between Onyks and AK-74U. The Russian gun and the Onyks prototype have a rear sight mounted on top of the receiver cover. The production guns (and Onyks' replacement - kbk wz.96 Beryl) has rear sights mounted at the rear of a mounting rail attached to the receiver. Thanks to that an identical receiver cover can be used on both Tantal and Onyks.


Varients:
wz. 89 Onyks: 5.45 mm
wz. 91 Onyks: 5.56 mm NATO
kbk wz. 96 Beryl: 5.56mm NATO improved version with new stock and improved receiver with base for optics.


Note:
A limited number of Onyks were used by the Polish military.
