So they told you there was a possibility it could be fixed under warranty, even though your warranty had expired? They told you to send the whole bolt in, and you refused? I don't understand what else you could want them to do. They're prob wanting the whole bolt to try and verify that it hasn't been shot very much. For all they know, you've shot it everyday for the past year and half and are just trying to get some work done for free.

If you really did buy a new gun then just use that bolt and send the broken one in and see if they fix it for free. If they send you a new one sans your bolt handle and cerakote, then you have an issue.
