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.
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
Compared to the Tantal, the Onyks features a barrel reduced in length by 216 mm (8.5 in), 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 grenades. At its muzzle end, the device has a conical 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.[1] 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 m and 400 m respectively).[2] 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
