Boyds offers 700ML stocks but im not sure if they offer them already cut for the ram rod. The new Rem Ultimate ML stock is already cut and they pop up for sale occasionally.

I think Brownwells and Numrich still sell the 700ML ram rod retainer spring hardware. The ferrule from a new Rem Ult. ML might fit your new barrel too. Another thing with Boyds is they have no bedding pillars and its a wise investment.
