Quick comment on the Magpul Pro 700 chassis. If you're buying one always get the folding version!
On the fixed version, the cheek piece blocks the bore just enough you can't get a cleaning rod into it - even if you lower the cheek piece all the way down.
I learned this the hard way, now I have to cough up another $150 for the hinge.
Haven't yet shot the rifle, so I can't give any feedback except to say it's heavy but very, very well built.
