Vampire: The Masquerade – Bloodlines Wiki

Even if the Steyr AUG AI was lackluster as a weapon it would still have a lot going for it aesthetically, but this lightweight Austrian assault rifle has proved reliable and effective, making it a popular weapon in militaries around the world. A 4X scope is attached for improved accuracy.
―In-game Description

The Steyr AUG is a ranged weapon in Vampire: The Masquerade – Bloodlines.

If the fledgling has a low firearms skill, aiming through the scope is difficult, as the view sways quite a bit. Full firearms skill, however, holds it perfectly still. This weapon is occasionally used by the Sabbat, Ming Xiao's Kuei-jin henchmen (Unofficial Patch+), and is the standard-issue firearm for the vampire Prince LaCroix's personal SWAT team.

Although chambered in 5.56mm NATO, the most damage it can do is 16 damage points per bullet, even with a headshot. This is odd, as the Uzi is, at some point, capable of causing 28 damage points, which is partly explained in the game by how vampires, not needing a metabolism or functioning internal organs other than their heart, are not fazed by yawing or tumbling bullets as much as straight-traveling high-caliber rounds.
