I seem to remember that Ruger replaced someones cracked receiver a little while ago. I'm not sure what the legal/warranty specifics are but, I know that it takes awhile because they have to wait for production cycles to come around so that they can strike a fresh one with the specific serial number.

doh, beat me to it.

They destroy the original. At least that's how it worked with ar15's.
