I sent the scope back to the retailer, Optics Trade EU. They took over the process from there and it is back in South Africa. I haven't had a chance to mount and test it, the gun is currently at the gunsmith for some cosmetic work (engraved grip cap). Optics Trade are great to deal with, however Swaro did not even want to entertain the idea that there might be an issue. Also when I contacted them afterwards, they referred me to Optics Trade. In short, they did not blow my hair back... It sounds like the scope was rebuilt, however I can't confirm anything and look forward to testing it.
