5.8 X 42 CHINESE

China started development of the 5.8×42mm / DBP87 in 1979 and finished in 1987. The 5.8×42mm / DBP87 was designed to replace the Soviet 7.62×39mm cartridge used by the People’s Liberation Army. The Type 95 / QBZ-95 (Chinese: 轻武器,步枪,自动, 1995; Pinyin: Qing wuqì, Bùqiang, Zìdòng, 1995; literally “Light weapon, Rifle, Automatic, 1995”) 5.8mm caliber assault rifle, firing the 5.8×42mm / DBP87 or the improved DBP95, is now the standard issue weapon in the PLA. The 5.8×42mm is an example of an international tendency towards relatively small sized, light weight, high velocity military service cartridges. Cartridges like the American 5.56×45mm NATO, Soviet 5.45×39mm and 5.8×42mm allow a soldier to carry more ammunition for the same weight compared to their larger and heavier predecessor cartridges, have favourable maximum point-blank range or “battle zero” characteristics and produce relatively low bolt thrust and free recoil impulse, favouring light weight arms design and automatic fire accuracy.
