I have one, photographed and played with it yesterday for the revision. I don't see how it could be very sturdy and therefore not accurate. One interesting thing is that it will work on almost anything with the rear barrel sight dovetail. In it's favor it is quickly removable.
I certainly wouldn't trust one in say .300 Sav. I have zero problems with the Miller on my 22 HP. If fact, I was amazed at the accuracy. When I get home tonight, I'll snap a couple of the mounts on my rifle.
