Just my opinion, but I think it's another case of a solution in search of a problem. If I was a law enforcement officer, and I was in a situation where I needed a rifle, I think I'd want a semi-auto... And if I have to lug around AR magazines anyway, I could just as easily carry an AR, don't you think?
BTW, there was a review of this rifle in February's (I think) "Guns" magazine. The author was quite impressed by the rifle's 4MOA accuracy (using a Leupold scope, IIRC), and he particularly liked the way the stock recoil pad tamed the "brutal" recoil of the .223 round..
