Yes, I have one of these mounted on a Ruger American Predator in .223 and it is my main p-dog gun. If you sit back a couple hundred yards and run a suppressor, it can take the varmints a while to figure out what is happening...
So yes, I like the scope. I also have a couple of Vortex Vipers to compare it to. I don't know if the glass is as good as the Vipers, but it is pretty close. My main complaint is that the detents on the windage and elevation knobs aren't as definite as on the Vipers - they are a bit mushy. They aren't bad, just not as positive as the Vipers. Adjusting the distance focus (not the reticle focus) is also touchier than the Vipers and did take some getting used to. I usually don't run it higher than 18x for p-dog hunting (for better field of view) and that helps somewhat.
But the one I have mounted now is the second one I've owned. The first one was a dud out of the box. I had already been using the above mentioned rifle with good hand loads under another scope, so the rifle/ammo combo was known good. So when I couldn't get the new scope sighted in, I knew it was the scope. It didn't track correctly at all. It would move in random increments when dialed, or sometimes wouldn't move POI at all when dialed several MOA.
I had purchased it from Cabelas, so I took it back there to swap it out for another. This was fun... I explained the problem to the guy behind the counter. He did ask me if I had run the box test and I told him no, because I couldn't even get an accurate zero. So he proceeded to tell me there was nothing wrong with the scope and the problem was simply that I didn't know how to "use the knobs". He then spent the next couple of minutes explaining to me just how experienced HE was. At the end of his diatribe, he told me to take the scope home and try it again. When I refused to do that, he got pretty huffy but eventually did agree to swap it for another. And the second one, as mentioned above, works just great.
