yeah if you are going to a remington style barrel you should be able to still use the Savage Lug. I would get one of the aftermarket ground lugs. Northland Shooting Supplies has a really nice one, so far I have two and will be getting more as needed.

I am assuming that you are aware that Remington and Savage Barrels have different threads, and that you are interested in have a savage barrel done in the Remington Style with a shoulder rather than a Barrel nut.
