I've replaced factory stocks multiple times using McMillan, HS-Precision, B&C, Brown Precision and a couple of cheaper versions. Never once did accuracy improve. I don't spend money on an aftermarket stock until the rifle proves it will shoot.
If the aftermarket stock shoots better than the factory stock it is only because there was a bedding problem with the factory stock that could have been corrected.
I buy aftermarket stocks primarily for weight savings and stability in changing atmospheric conditions. Plus I just think they look better. The B&C is heavier and no more accurate. But some like a heavier rifle and shoot a heavier rifle better. But the rifles potential accuracy will be unchanged. If that is your goal then they are a decent mid grade stock.
