One of the earlier ARDE developments was the 7.62 mm 1A1 self-loading rifle (SLR) and its ammunition which replaced the Ishapore 2A1 bolt-action rifles (based on the 0.303 Lee–Enfield rifle) in Indian Army service then. Over a million rifles have been produced by the Rifle Factory Ishapore, and were used in the 1965 and 1971 Indo-Pakistan Wars.
