I haven't actually shot one, but I did get a chance to handle one pretty extensively at the Shot Show.
My impression is that is is very nicely made, fit and finish is awesome. The cheek pad is smallish but is adjustable both for and aft and up/down. The folder locks up tight. My impression is if these were the same or similar in price to an AX chassis, they would be a fairly viable and popular option. Since they are over 2k, they have realistically priced themselves out of the market. I'd be in the market at < 1500, but it is difficult to rationalize 2100+. It IS a very nice product though.
