At 6.5lbs I don't this this is intended as or would make a good PRS rifle, if's that is what you want get a T3x CTR and drop it in a KRG bravo chassis, mush better for a PRS rifle at the same price.
I think this is for guys that like chassis rifles and want to hunt with them but don't want the weight of most chassis.
Sig got a lot right on this rifle in my opinion:
Light (6.5lbs)
Fully adjustable, butt pad even has height and cant adjustment
Switch barrel
Sub 1/2moa accuracy
Folding stock
Nice two stage trigger(I've heard from people I trust, obviously have tried one)
Only thing I would want to see is a 3 position safety or even like the Tikkas and the bolt locked when on safe. Yes I realize the stock folds over the bolt but I cant see me carrying it while hunting with the stock folded. In most situations where I would have the stock folded It would be unloaded(transport, storage, etc)
All that said, it might be my hunting rifle next season...
