Probably the easiest,drop in, no bedding stockout there are the HS-Precision Pro-Series with the aluminum bedding block already installed. Simple bolt on and go.No messing with epoxies. you do need to be careful torquing down the action bolts though,they will crush the block.
But McMillan,HS Precision,Bansners,Bell & Carlson,Hogue all make good stocks that are direct replacements for your 700.you just need to decide what you want and go from there.
