During the Homeland War Croatia got a large quantity of Russian AKM rifles with 6h4 bayonets from Lithuania. Many Croatian soldiers had Russian 6h4 bayonets.
Both 6h4 bayonets, made in Tula and IZMASH were common in Homeland War. Most interesting models for collectors are hybrid ones with mixed Tula/IZMASH parts. These bayonets were resembled in Bulgaria, then sent to Lithuania and from Lithuania to Croatia. Some of them were directly sent from Bulgaria to Croatia.
