I'll add my $.02 to the other good suggests.
I've done several builds and have had great results with Green Mountain Barrels and either
http://www.revivalindustries.com/ or Boyds thumbhole stocks. Midway owns Fajen and Adams & Bennett barrels(made by GM) and often offers packages.
A couple of tips:
Flutes on a rimfire barrel are cosmetic and not functional. I like them...but they're for looks only. Barrels are available in 16.5, 18" and 20" with 18" mostly likely the most popular/available length.
There are several varieties of laminated thumbholes. Boyds has their Evolution, Blaster, Ross and Revival has their Tundra, Yukon.
Fajen calls there's the Silhouette, I believe.
Remember to include in your budget the ancillary "must have" goodies we all can't live without!
Here's one of mine which I bought unfinished. I finished the stock myself. It's a Revival Tundra with 18" SS Fluted GM....and most, if not all the bells and whistles!
Good luck,
SD
