Burris Fullfield II Tactical 4.5-14 x42
I bought one of these last year and put it on my 25-06. It's 'tolerable' but not what I would call 'good'. It seems to be durable enough (holds its zero; hasn't fogged up; etc.) and it seems to track fairly well. I'm able to keep everything sub MOA out to 600 yds (as far as I've shot with it) but it has 2 issues. The target adjustments are what I call 'squishy'. They don't click nicely at all and sort of 'move' (e.g. you go up to 2 MOA and you can't really tell if it's 2 MOA or 2.25 or 1.75, you really can tell but its nothing like Right On and then when you go back to zero it's more like zero +/- 0.25).
The issue that I LOATHE is the fact that the objective lens turns when you adjust the power of the scope. If I were building a squirrel rifle I probably wouldn't care but on a big game rifle with scope covers on it its terrible because your scope cover may flip up when you're on 4.5x but on 14x it flips down and interferes with the operation of the bolt. Not nice.
If I had it to do over again I'd spend the same money on a Nikon.
My 2 cents.
