That's a pretty broad question since there are many Master Gunsmiths around the country, and each may have a slightly different set of skills depending on what you want and/or need to have done.

There are a couple in the mid-west, but their schedules are ususally booked far in advance. That means if you don't have enough time left in your life to order green bananas you may find it difficult to schedule.

If no one is giving you word of mouth references, you could go to the American Custom Gunmakers Guild web site and ask - http://www.acgg.org/learn.html
