For the recall: when I did it a few years ago, they sent me the part so my own smith could do it. Didn't require shipping anything directly to them. They also used to send a little check to cover the service (it didn't, but nice thought).
I have a post-64 in 243 that, when kept clean, works flawlessly. As was mentioned above, I'm convinced 95% percent of the jamming problems people report are tied to dirty guns.
