If you're insistent on not making changes to whatever you buy, then buy whichever has a stock that fits you best. Better yet, buy one with at least an adjustable cheek piece. A floating chin weld is not beneficial to accuracy. That's actually the reason I suggested Remington. There are many aftermarket stocks available and you should be able to find one that fits.

The comb on the McMillan on the FN might be high enough depending on what rings you use.
