I've obtained an older Leupold BR-36X scope and am confused by the adjustable objective feature on it. All of the previous Leupold AO scopes I've owned have had the yardage markings on the turning ring, with a mark on the scope tube to line up with the various yardages. On this BR-36X, there are two rings of yardage markers, and that's what I'm finding confusing. Here's a picture of the objective bell and AO adjusting ring. I'm tempted to think that you need to line up the two ranges--one on the turning ring and the other on the scope tube, as I have in the picture with the two 100-yd. markings lined up with each other. But maybe I'm missing something here (happens frequently
). I bought the scope used and didn't get a manual with it. Can someone familiar with the Leupold BR scopes help me out here?
Thanks in advance.

Thanks in advance.
