Have you tried the obvious choice, contacting Savage Customer Service? They may want you to sign a waiver to ship that part to you, or just have it shipped to your gunsmith. If the C.S. person won't offer you the choice of signing a waiver, call back later and talk to another person, it seems to make a difference. It seems that some just don't want to do the extra work, but most will work with you. Just be nice and sprinkle your words with plenty of sweetness (it's good practice anyway) and you'll have a bolt head in your hands quickly. Be sure to tell them you're shooting a contest in two weeks, that'll often help to grease the rails.

Savage is by far the cheapest source of Savage parts, and you pretty much know they're in stock.
