The paper is aimed at introducing to the academic community the main results of chronological study of the ranged weapons found at the excavation site of the Stepushka-I burial ground of the Xianbei-Zhuzhan Time in Central Altai. This archaeological site was investigated by Altai State University’s expedition during the summer and autumn of 2010 at the highway construction area. The period studied, from the end of I millennium B.C. to the first half of I millennium A.D., is marked by the further development of offensive weapons used by the Bulan-Koby’s population in the Xianbei-Zhuzhan Time. Most types of compound bows and iron arrowheads can be dated from observable chronological framework (II–V centuries B.C.) The paper presents a detailed description of the obtained material sources, classification and typology of bows and iron arrowheads, their functional elements, its typological analysis and analogy of the artifacts found in the archaeological collections of monuments of late I century B.C. — the first half of the I millennium A.D. in different regions of North and in Central Asia.
