No arsenal cartouche, no Chinese ideographs, Latin-alphabet DB, DP, DK, or M-21 stamped on left side of receiver as prefixes. It is suspected “B” represents Bangladesh, “P” represents Pakistan, and “K” represents Kampuchea. One sample examined reads “M-21 DP” so combinations of these figures may be encountered.
D, P, X and other Latin characters appear occasionally as a suffix to a serial number upon an arsenal cartouched, PLA-issue weapon; their meaning is obscure although “X” appears to indicate a thorough arsenal rebuild and “P” may represent “accuracy rifle” cited in one published guide. Such suffixes do not identify a rifle in this category! Only prefixes count.
Huge quantities of carbines were manufactured at Chinese arsenals intended for transfer to the People’s Army of Viet Nam and the so-called Viet Cong once the United States Air Force eliminated North Viet Nam’s limited production facility. They are usually indistinguishable from PLA-issue in most cases, bearing arsenal cartouches and Chinese ideographs. One sample has emerged that appears all original, set in a synthetic “jungle stock,” exhibiting a very uncommon arsenal cartouche, and a 1974 production date. As Beijing and Hanoi fully anticipated the war within the confines of the Republic of South Viet Nam to last for a number of years beyond that year, we can be reasonably confident that the rifle in question could well have been manufactured for lend-lease (non-PLA issue, in other words) only consigned to storage when international events took unexpected turnings. Such samples belong above and not in this category.[/list:o]
Numbers: Uncommon.
Comments: These weapons were built to the PLA-issue standard in all respects.
