Anyone know for *sure* when the US armed forces went from 20 to 30 rd mags
for the M16 service rifle? Was it during the Vietnam Campaign?
It came up in conversation last night. How would one look it up? Army
Ordinance records?

Thanks guys,

From http://en.wikipedia.org/wiki/M16_rifle half way down if we can trust

The magazine release is on the right side of the rifle, ahead of the trigger
guard. Current military magazines have a capacity of 30 rounds, as opposed
to the 20-round magazines issued in Vietnam. (30-round magazines were not
developed and issued until late in the war.)
