Agreed. I’m sure it has a 50mm objective. $500 is a great price and there’s nothing wrong with the those older VariX scopes. Buy it!
No, I don't think so. The Leupold VARI-X III 8.5-25x50 is a 30mm. scope with side parallax focus. This scope has a 1" main tube and AO instead of side focus. It is marked on the gold ring on the objective bell just as "Vari-X III 8.5-25", without any lens diameter specified. I measured the OD of the objective bell, and it comes in at a little under 2". I think any 50mm. objective would have a larger OD--probably something like 2.20".
