AR stands for Armalite Rifle. Accept no substitutes.
While some believe AR stands for Assault Rifle or Automatic Rifle, this, of course, is incorrect. It was named after the company that developed it in the 1950s – Armalite. Armalite is truly the original AR. Made in America, these modern sporting rifles are blessed with phenomenal accuracy, reliability and ruggedness. Their striking appearance is readily recognised. ARs are true all-weather firearms that are versatile enough to suit target shooters in national matches and hunters of everything from varmint to big game.
