Poznámka:
Note:
Zbraňový systém vytvořený v 60.letech minulého století. Od počátku byl vyvíjen na "západní" munici, protože se předpokládal export. Závěr byl obdobný jako u německého kulometu MG-131, u URZ se však hlaveň při odemykání závěru nepohybovala. Nábojová komora byla opatřena Revelliho drážkami, usnadňujícími vytažení vystřelených nábojnic z komory. Ústí hlavně bylo upraveno tak, aby bylo možno vystřelovat puškové granáty. -

The URZ system is, in a way, a building block that allows several weapons with a high proportion of the same components to be created on a single basis, with all the advantages that this brings. 4 weapons have been created - automatic rifle (AP) - single shot weapon, light machine gun (LK) - versatile, bipod, heavy barrel, heavy machine gun (TK) - single shot weapon: - differs from the light one only by the tripod, external cartridge box (250 pcs), optical sight, tank machine gun (T) - for vehicle mounting, with electromagnetic trigger, no single shot switching mode.
Same for all guns is the bolt carrier and bolt, which is semi-locked. The bolt tension crank is at rest when firing. The firing mode selection is combined at the same time with the safety. The barrel of all guns is solid, the AP barrel is lightened, and the heavier guns have an anti-wear coating on the barrel. On all weapons there is a special attachment on the barrel for firing Czechoslovak rifle grenades. The weapons include a small magazine for rifle cartridges. Of course, there is a training attachment for firing practice ammunition. The sights consist of a peg sight and a diopter sight (visor). The guns allow to mount an optical sight.
A large capacity drum magazine allows the weapon to be supplied with an external source of belt-fed cartridges from the clip.
