My personal experience with Manners is limited (have only been around them briefly, have not owned one), but they seem like nice stocks. Manners seems to get good reviews - in fact there was just a thread in Custom Rifles & Wildcats about them. I'll seriously consider a Manners on the next rifle I have screwed together.

Something like a Manners MCS-T with the carbon fiber shell might be a good option.

As far as turreted scopes go, it's pretty tough to beat an SWFA for the money. Or at all, for that matter!
