Yes, some AF Reserve and ANG units are still using M16A1s. This is the reason that M193 is still being made at all. But it is purchased in a fraction of the quantities that the US miltiary buys M855, so it does not make financial sense to make two different runs of brass. IIRC, the last separate batch of 5.56 brass (i.e., non-NATO marked) was made in '93.
