MIL-STD/MIL-SPEC for M16?

[CWLFTMFW]

I know this is a pretty strange question, but is there a mil-spec or mil-std for the M16? I know there’s the MIL-STD-1913 for the accessory mounting rail, but does anything like that exist for the rifle itself? Or maybe one for the M203 Masterkey ? I’m browsing a spec site and just curious.
