Development of the AR-10 and AR-15
Late 1950s
At ArmaLite, Stoner spearheaded the design of the AR-10, a 7.62mm rifle intended as a replacement for the M14. He also conceived the AR-15, a smaller, lighter 5.56mm rifle. The AR-15, designed with lightweight materials like aluminum and plastics, quickly gained attention for its accuracy, manageability, and high rate of fire.
