Sent in the rifle because the front half of the bolt was locked up solid inside.

S&W shipped the entire rifle to and from on their dime, replaced the bolt, polished the chamber and sent it back all at no charge. This was all long after the warranty should have expired.
S&W has a lifetime warranty.
