5RAR soldier's personal weapon 7.62mm
FAL, SLR (Self Loading Rifle).

The L1A1 is the Australian version of the Belgian FN FAL rifle. It entered into service with the Australian Army in 1959. The L1A1 was a reliable, hard-hitting, gas-operated, magazine-fed semi-automatic rifle, with a maximum battle range of 300 metres and a practical rate of fire of 20 rounds per minute. In Vietnam the L1A1 was the standard personal weapon of the Australian soldier. With a full 20 round magazine it weighed 4.96Kg. The standard issue was 5 magazines per rifleman but almost all carried as many filled magazines that they could get their hands on, often dispensing with food rations in order to find room for the extra ammunition. The rational to this was that the extra 7.62 mm rounds fired from an SLR rifle would do more damage than throwing a can of Ham and Lima Beans.
