Thats a pretty open ended question. there are several different stocks that you can buy for your 700. McMillan,HS Precision,Bell & Carlson, Bansner,etc that all make stocks that will bolt right up. You need to look through a catalog or Midway USA to see all the different versions, pick one you like and fits your needs and have at it.
As far as bedding goes, that is purely choice. Some stocks come with an aluminum bedding block already installed so you dont have to mess with epoxies. Just depends on what you want out of your rifle.
Hope this helps-Tim
