Awesome scopes, i own three. With that said, I'll never buy another. This is because of the worst customer service I have ever experienced.
The third one I bought, I tried on three different rifles, shooting over 80 rounds total trying to get a zero. Finally after 3 rifles, I was sure the scope was to blame. So I sent it back. It wasn't that the scope wouldn't hold zero, as it that just fine, but I could not touch the adjustments with out the thing going wild. I would move it, for example, one click to the right. My POI would go 3 in to the right and 2 high, but it would hold a zero where ever it ended up.
Burris sent it back to me saying that it was my gun's fault. They even shot a target with it, proving that it would shoot groups, but the problem is not that it would shoot groups, it was just impossible to sight in...
So I tried it again. Hours at the range waiting for barrels to cool, switching rifles, tightening screws. Same thing. So I sent a lengthly letter and some shot targets to Burris along with the scope AGAIN explaining the problem. They ignored my letter and didn't even adress the actual issue. Again I got a target with three holes in it saying that the scope held zero just fine...
So I REALLY had it out with one of the guys on the phone. And sent it back a third time. They still denied fault, saying the scope was perfectly fine. But this time I took it out to the range, stuck it on one of the same rifles, with the same ammunition and zeroed the scope in three shots. I think what happened is that on a really close examination, and by actually listening to what I told them was wrong with it, Burris discovered a problem, but by then was too proud to admit it.
I will never buy another Burris product again, however I will admit that they make a good scope when they work. My other two work just fine, but Leupold makes as good of a scope and will actually stand behind their product.
