Ukrainian state-owned firm RPC Fort (Research and Production Company Fort of the Ministry of Interior of Ukraine) is manufacturing under license a variant of the IWI Tavor chambered in 5.45x39mm Russian.
The Armed Forces of Ukraine are still primarily armed with 5.45x39mm chambered firearms inherited from the Soviet Union. They have adopted a small number of RPC Fort-manufactured 5.56mm Tavors, presumably in use by special forces.
Israel manufactures the Tavor in 5.56x45mm and 9mm. It has been claimed that India is manufacturing it chambered in 5.56×30mm MINSAS but I have seen no evidence of this and am skeptical.
