It might be a little of a drive but Eric at axis works or tod at southern express or Keith at Phoenix custom rifles would be my top 3 for any custom rifle builds .They are all around Phoenix and there guns and reputation speaks for itself. They are probably 3 of the best builders around.
When I lived in Flagstaff I used Gary Reeder a couple times and his work was excellent. In addition he was was able to get to the work in a reasonable timeframe. I’ve had other smiths quote me a month and 6 months later they still hadn’t touched it.
Small sample size but I inherited a colt python from my uncle that he unfortunately kept on his boat in Florida. It was in very rough shape. I thought it might end up having t be a wall hanger. Took it to Gary and I was stunned how good it looked and performed. He also did a barrel swap on a savage for me. I know that is simple work but he did it on the spot while I waited. I understand some people find him controversial but I have had good luck with him and have just talked guns with him in his shop numerous times and he was very personable to me.
