BUR #16646 has been approved by @nonamethanks.
create alias beretta_ar70 -> beretta_ar70/90
Why are there two tags for the same assault rifle model? I'll change the alias in less than a day if you prefer the opposite way, as Beretta AR70 can also cover the earlier variant used from 1972 to 1990 (Beretta AR70/223, see post #6060515 for reference) as well.
