I am looking for a like new or new one that is factory stock. I have noticed that the stock ones that have a really low round count are almost as much as the new ones, so I think I will just spend the extra $100 and buy new.
I also want to shoulder one, just one more time to be sure that I want one.
With that being said, if I came accross a really nice used one that is stock, then I may buy it.
