Whether or not Savage might sell that part may depend solely upon who you talk to in Customer Service. I've had mixed results getting so-called "restricted parts" by signing a waiver. Seems some there don't want to take the walk over to the fax machine. But if that's the case, you can have a gunsmith order the part for you. Mine did it for free, but I was also paying him $175 to thread a barrel and install a tuner. ( He did a beautiful job).

If you can get the part from Savage, it'll be the least expensive source you go to. So I would start there first.
