During 1967-68, as the Koreans were being re-equipped with M16/ M60s, the Koreans proposed to give to the ARVNs their M1/2 Carbines , M1 Rifles, BARs & Browning MGs. (and I believe had already started to do so) when the US told the Koreans “NO, junk them or send them back to Korea”. So the US had the final say in the disposition of at least the Small Arms Korea took to Viet Nam, whether all Korean SAs I do not know.
As the results of this, I obtained a ¼ ton trailer full of stripped M1&2 Carbines receivers , selected the best and gave the rest back.
And a few months later I was involved in a thrown together team to rebuild ARVN Small Arms, because all of a sudden the ARVNs were way short. And we got most of our spare parts from the Koreans..
