I had the combo you described, just sold mine a couple weeks ago. I was smitten by the idea of using AR parts I guess.
The MDT chassis is a quality piece and well built as well as their ten round mag which fed like butter. I've had Badger and V-bull systems before with steel AICS mags and they are always somewhat notchy. The combination of the LSS chassis and the polymer mags blows them out of the water for smoothness.
It shot tight enough, but at the end of the day the novelty wore off. I just couldn't see much point to a bolt action with a pistol grip, every time you rack the bolt your removing your hand from the grip and I found it slower to reset my trigger finger/hand then a conventional stock if that makes any sense.
Also the 16.5" AAC likes bullets heavier than 150r and velocities over my chrono were pretty lethargic.
Two words... muzzle and blast. You can feel the pressure wave in the fillings of your teeth!

Only way I would enjoy a 16.5" .308 is with a can and subsonic like they are meant to run but we all know that isn't happening anytime soon.
