I also read the AR article on the Darne the Lt Col brought back. Nothing indicated it was actually used by the Viet Cong as I recall. It was selected from a piled up heap of all types of guns in a warehouse, probably many of which were confiscated civilian guns, which this Darne likely was.
I do not now recall the reason now but this LT Coll was allowed under proper authority to select One (1) gun as a personal souvenir to bring back to the states with authorization. He picked the Darne, an R10 as I recall.
