You haven't found a load for one, Mark? I can't find any details of one online.
Probably should have fitted an ACOG myself. After the SUSAT had the mount modified, it probably sits higher overall, and what I really liked was being able to get a good cheek-weld whilst using a scope; a lot of bullpups can't manage this.
It looks funny as Hell on the rifle. Because they have no eye relief, it has a long reach-back mount which sits it roughly at the start of the ejection port. Has to come off to fit in a case too.
It would be an excellent scope for a flat-top AR, but the Steyr rail is just a bit too high.
