In the early 70s, Beretta set out to develop a less-expensive, modern rifle that fit the NATO standard of a 5.56 chambering. So after keeping a close eye on the Colt AR-15 and then Armalite's development of the AR-18, Beretta combined attributes of both guns and created the AR 70. Beretta sold quite a few of these rifles in Indonesia and some other countries, but the gun never garnered much exposure. Despite this, it was a state-of-the-art design for its time and if found can have a hefty price tag due to the fact that they are no longer imported into the United States.
