Yes, Todd Nelson (Country Gentleman) is down is Cherokee AL about 2 1/2 hours south. You can either make an appointment or ship your stock to him, but if you ship you do not get the benefit of the personal fitting. Best way to get in touch is to text him.
There is also a guy in Hendersonville (I believe) that does stock work. I've seen a few adjustable butts, but I don't recall seeing a comb done by him.
Tron is in Michigan, not close , but top notch. He did a perfect adj comb on my XT, quick turnaround. Only info I have, I am sure the others mentioned here are top notch. Good info here. Good luck, Al Baker
