Only what I read and saw. A guy had one at the club in 308. They're built on a Savage AT action, use a shouldered barrel instead of the nut, aftermarket recoil lug and stock. I assume the receiver face was squared, but what other tweaks they may do, truing, timing and etc I don't know. The guy at the range wouldn't let me rip his apart to see for some strange reason.patonyk said:They are producing a gun called the Mark VII with multiple options. ANY experience??
