Some info here:
I've seen them discussed a bit on some of the various gun-related websites, but haven't seen any exhaustive tests yet. I handled one at a local shop; I liked some features but disliked others (such as the 180-degree safety lever and "fake" bolt catch). The price was a turn-off as well (they wanted $650).
Let us know how you like yours, how well it shoots, reliability, etc., once you get to shoot it a bit.
