I have 5 Nikon scopes and they are a great buy for the money. I have one 4.5x14 with BDC ret. and I don't seem to have a problem however, a friend of mine hates it. He say's his eyes are automatically drawn to the circles and it interferes with his seeing the cross hairs. Personally, I would rather not have the bdc but it is already there so I live with it. Nikon scopes are bright, crisp, and clear with a lifetime warranty so you can't go wrong.
