I have a Leupold Var XIII 6 x 20.
Very clear at all distances. Excellent scope.
Something inside it broke a couple years ago and I had to sent it back to be repaired. I got it back in about 3 weeks good as new.
Even though it failed on me once I would still recommend it.
If I was going to buy new scope now I would buy one with the ballistic plex reticle for long range shooting.
I know Burris has this available in their scopes but their Signature series scopes are very heavy.
