Thanks for the additional replies to date. I did contact Steyr UK before my latest posting on the matter but got exactly the same response as Tinbum. I then asked about buying a SA Receiver as a stand alone item but it was suggested that the cost would be prohibitive.

The only "cheap Way" I've found of getting one to date is to buy a SA without stock and mags and swap across the bits from one of my standard Hunting 5's when I want to go SA. Even this approach would cost around £1600 or so.
