Frequently Asked Questions

What is the Steyr AUG, also known as the StG 77?

The Steyr AUG (Armee-Universal-Gewehr), or StG 77, is an Austrian bullpup assault rifle developed in the early 1970s. It replaced the StG 58 (FN FAL variant) and was designed to be a modern 5.56mm intermediate cartridge rifle, featuring extensive polymer use and an integrated optic.

What are the key features of the Steyr AUG's progressive trigger?

The Steyr AUG's progressive trigger is a unique design where a short pull activates semi-automatic fire, and a full, longer pull engages full-automatic fire. This system eliminates the need for a separate manual selector lever, simplifying operation.

How does the bullpup design benefit the Steyr AUG?

The bullpup configuration places the action and magazine behind the trigger group. This allows the Steyr AUG to have a standard 20-inch barrel length while maintaining a significantly more compact overall profile compared to conventional rifle designs, enhancing maneuverability.

What kind of optic does the Steyr AUG typically feature?

Original Steyr AUG models come equipped with an integrated 1.5x magnification optical sight. This optic features a simple circular reticle, often nicknamed the 'donut of death', and includes emergency iron sights molded into the top housing.
