It's takes a lot of work to leave that much equipment. Soldiers will take anything that isn't nailed down and are excellent smugglers. They must have used sorcery to keep the guys from filing their pockets full of NODs and automatic lowers.
I believe that a DIAS could probably be manufactured from an MRE spoon so long as it can be bent and hold shape, which would allow you to convert any(?) semi on the platform to fully auto, though for models which fire a larger cartridge the dimensions would probably be different. I haven't seen any examples of a DIAS for an AR-9, -10, or -12.

You can buy civilian lowers which match the original M16 specs except for the "third hole' which accepts the pin for the auto sear.
I had an armorer tell me you could modify most semi-autos to be fully auto with an MRE spoon.
