Steyr Arms is now importing the original AUG A3 scope. The scope has a magnification of 1.5x and an objective aperture of 14mm.

On their website Steyr state that it has a “Crosshair/crosshair” reticle. I think this is a typo. I doubt they would have changed it from the military circle / crosshair configuration. The circle is sized so that a man sized object fits inside it at at 300 meters. UPDATE: Steyr have confirmed that it is indeed a circle/crosshair reticle.

It is not cheap at $799, but is probably as tough as nails.

UPDATE: Steyr have told me that Swarovski Optik no longer make their scopes.
