I ordered the parts for this right before savage rolled out their precision models based on MDT chassis, so I wasn't surprised when they brought it out. I originally had a 6.5 284 barrel on it--but yanked it and replaced it with a Criterion 280 AI using an Axis 2 receiver and accutrigger. I used a MDT standard LSS chassis which IMO is way too short to balance well, so I cobbled together my own franken-foreend which works fine (and cost me about $30 in materials). I have MDT's folding stock adaptor which I find is very useful in making the gun more easily transportable. I had a spare Luthar buttstock (which I hate on AR's) but find works well with the MDT.
