The first M-16's (the M-16A1's) that were used in Vietnam had a fully automatic setting on the selector switch. All other versions of the M-16: the A2, A3, and A4, are only capable of single and 3-round bursts.

Licensed M16s are manufactured in other countries, who do not use the three round burst. Canada, South Korea, the Philippines, Singapore, and Malaysia have all manufactured licensed M16 variants.

And to correct a flaw in the first answer, the M16A3 actually is full auto - M16A3 was not a military nomenclature. The designation came from Colt, and it was intended to be an M16A2 for export customers who were not particularly keen on the three round burst limitation. So it used the M16A1 trigger group.

Depends.

m16a1 and m16a3 are full, m16a2 and m16a4 are burst.
