Steyr AUG rifle
One of the first semi-automatic rifles to be constructed using polymer components, the AUG is one of the rifles in daily service with Austrian military forces. Utilizing a polymer box magazine that attaches in a bullpup configuration, this rifle has as its primary sighting system a 1.1X optic built into the receiver carrying handle.
This firearm was donated in 2007 from the family of Bruce Stern. Mr. Stern's military firearms collection was one of the largest private collections in North America.
