The AUG A3 features a below-average rate of fire for a submachine gun, with mediocre damage and a slightly above-average magazine capacity. That being said, it also has a steady recoil that makes it easy to control in long bursts. Overall, the gun is better suited for headshots rather than shots to the body, where its damage leaves something to be desired.
The in-game name of AUG A3 is misleading to the real-life model since the weapon is actually an AUG A3 9mm XS, an updated version of the AUG Para based on the AUG A3 assault rifle. The main difference between the AUG A3 and the GSG 9'sAUG A2 is that the A2 has a raised top rail, while the A3 has a flat-top. The AUG A3 9mm XS also has an underbarrel rail in place of the AUG A2's built-in foregrip. The AUG A3 assault rifle, however, can have either a built-in grip or an underbarrel rail.
The sight rail is for some reason skeletonized, whereas the real-life one is solid.
The real-life AUG A3 9mm XS uses a 32-round magazine, meaning that it should have a capacity of 32+1 instead of the current game's 31+1 capacity.
