The factory warranty is worth about as much as a bucket of spit, warm or otherwise.
Want to talk about second guessing, live through the 15 seconds of life it takes to run a borescope up a barrel when you get it back in the mail and ask if those seconds are worth the exact cost of a barrel that doesn't come from a random guy in Oklahoma through the mail who may or may not have done anything other than run a throating reamer up the action until it chambered.
For Bergara the warranty is an opportunity to up-sell, from Remington its a bankruptcy claim. I'd rather a local guy I can run into at Wal Mart and ask him to stand by what he did.
FWIW the local guy will fight it out over what he did, and still pop a yellow belly with you after. Can't buy that over the internet. Then he shoots top 30 at Kof2Mile and I'm in the "shut up" phase for approximately forever.
