I've got a decent amount of experience with H&S stocks. All of the Army's M24s come standard with H&S stocks which I liked enough to get one for my personal 700 PSS. As far as I know, they all have a thick palm swell and the aluminum bedding block as standard features. It's got a nice heavy feel to it and is pretty comfortable to shoot. The only difference between mine (in the picture) and the Army's model is that mine doesn't have an adjustable butt pad. I don't really have much experience with Mcmillan stocks so I really can't compare the two but for whatever it's worth, I like H&S stocks and apparently the Army does too.
