My first Armalite 180 was a Sterling, but was an 80s Police trade in according to dealer I got it from in the Seattle area. I think he said Costa Mesa or Anaheim. Too many years for this old brain to remember. I know the LA cops in the SLA shootout in Los Angeles had some AR-180s. I saw some documentary footage that showed them. I have always noticed AR-180s. Kinda like you first car....
