Had three presumably Chinese World Class's in the very late 90's; the reason I had 3 is, the first two physically came apart on my '06. They replaced them OTC. I put the third one on an air rifle and that's where it sits now.
Went with a Burris after that, which I ended up not liking. Then on to Leupold. Then on to... it's a journey with optics for sure.
These were made after the sale of the brand and were NOT the same scope as the original Euro Class which is amazingly tough and solid for the original money. I still use several Euro/Titans and have zero complaints. Can't say the same for Zeiss, Nikon, Pentax +.
