In the Austrian army, the Steyr AUG assault rifle is called StG 77, which is short for Sturmgewehr 77 (This just means assault rifle. The 77 comes from the year the weapon was introduced in the Austrian Army, 1977).
Here are some exact stats (they are from the homepage of the Austrian army, but i've learnd them often enough by myself, since i had to serve military duty)
- weight: 3.75 kg unloaded, 4.25 kg with a 30 round magazine
- caliber: 5,56 mm (NATO)
- length: 70 cm
- maximum range: 2700 m
- usual operation range: 300 m
- theoretical firing speed: 700 min-1
- practical firing speed: 60 min-1 (1 magazine change included)
- ammunition supply: magazine for 30 rounds
Opposed to Leynos wu, it has an optical sight which magnifies by 1.5.
The only steel parts are the barrel, and a few small parts in the gas pressure device (directly translated from german), the part which enables the gun to auto-reload.
The rest of the gun is black colored (not sure, it doesn't chip like enamel though) aluminum for the barrel housing, and plastic for the butt.
The barrel is removable, and there's some cleaning equipment placed in the end of the butt.
The operation is simple, just as Leynos mentined, a gentle pull on the trigger for single shot, a little more firmly for autofire.
Pretty mean eh?
From my personal experience, the gun is amazingly accurate once tuned correctly for the individual shooter.
Even for an unexperienced shooter is far from impossible to hit an object of the size of an 17" monitor (or a human chest, whichever you prefer) at the distance of 300 m with the first shot, if he's lying flat.
