Have the B&C M40 on a 700LR in 7mm, also have a Savage 10 with the HS stock.
To my surprise, the B&C is stiffer and less flex in the fore-end then the HS.
B&C use to be associated with meh stocks, today they make good stuff. Outfitted a few Vanguards with them as well. Prophet River usually has a no tax free shipping once a month so you can grab them for $399.
The Magpul stock is garbage, handled one at SAIL, ergonomics suck and it's far too skinny for target use. I'd shoot the rifle with no stock at all before I'd put one of those plastic POS on it.
