There is no doubt these are great scopes. I had one for a while and it must have been a lemon. I could not get repeatable adjustments, it had an oval shaped view, and small spot of debris in one of the internal lenses. I ended up getting it repaired under warranty, but it still never worked right. I ended up selling it.

I also had a Black Diamond 3-12x50 that was a monster of a scope. The Burris Diamond scopes are awesome optically, but they are heavy and it didn't quite fit on the rifle I wanted to use it on. I sold it too.

For the most part I was pleased with Burris and their customer service. I would consider Burris again.
