A lot of people recommend B&B on Jones Rd but I had an axis done there and was not happy. Also, I had them do a Sika and there has been a little hair slippage.
I used Brush Country forever (over 20 years), but have not tried them since the ownership changed several years ago. Check them out if you are looking for the absolute best quality. My only concern about them was that they were doing so many huge jobs for people coming off of African safaris and guys with Bighorn or Marco Polo sheep that I felt like my little shoulder mounts were kinda small fry for them.
