It has a gas-operated auto-loading system, with short piston, firing from closed bolt 5.56x45mm NATO ammunition. It uses either 30 or 42-round magazine. The ejection port is ambidextrous as it can fixed to throw the empty cartridge casings to the right or to the left. The charging handle is on the left side.
The AUG A1 version features a fixed 1.6x optic sight and a 50.8-cm-long barrel, whcih can be completely taken apart along with the forward handle when field stripping the gun.
