I'd have to second BigBulls's opinion on this one. I too did a lot of research before choosing my QAD that I'm currently shooting, and couldn't be happier with the choice. I have been shooting it extensively since June and have not had a single problem with it. I do shoot a good bit, and am not kind to my equipment through hunting season. I expect it to hold up to the riggers that a season can put on it, and this one has done just that.
All in all, would buy the QAD again if I had to do it all over again, without hesitation!
