Mostly. The biggest difference between the two is that the 721 safety wrapped around the rear tang of the action. On the 700 the rear tang is notched for the safety.
You can notch a 721 and use a 700 trigger, or you can relieve a 700 stock to use a 721 trigger.
Bottom metal's are different between stocks. Meaning, you need to use 721 metal with a 721 stock and 700 metal with a 700 stock. The actions will use either depending on which stock you are using.
Scope bases are the same. I use EGW 20moa's for a Rem 700.
My first 721 project was swapping in a 700 trigger and 700 magnum bolt and putting it in a Sendero Stock and adding a ER Shaw 300wsm Varmint barrel.
Current 721 project is using a 700 magnum bolt, original trigger, Knoxx Axiom Kings Camo stock, and a Douglas 7mmWSM barrel.
Both are using Cabelas Kwik Klip's that hold 7 rounds of WSM.
