I'd be making a call to JJ Perodeau and see what he can do for you.
Thank you! I spoke to JJ this morning, I am making arrangements to get him the rifle shortly.I second JJ perodeau. He's not the cheapest (he's the most expensive) but this is a critical repair that needs capable hands. It's also likely to be a less expensive repair in the grand scheme of things, on the average, so I wager JJ will charge you $50-$100 more than the shadetree gunsmith in this instance.
