 A successor to the vz.58 was proposed in the 1990s; the 5.56×45mm NATO ČZ 2000 assault rifle has been suggested as a possible replacement but due to a general lack of defense funds within the Czech Republic, the program was postponed.Another recent contender is the ČZW-556 assault rifle and ČZW-762 light machine gun which both use lever-delayed blowback which has more reliable accuracy and performance over the gas operation.
