Mike, I have seen Classic Reboring's add in Rifle Magazine and the add say's the business is for sale. He might not be doing the work his self. No matter, it's still a bad experience for you. I went through the 527 carbine problem because I wanted a 1-9" twist 223 but the boss around the barrel for the rear sight would have made to much work to duplicate and I didn't want to have a re barrel without the boss for the rear sight, so I wound up trading for a 1-9" long rifle. Hope you have success, you certainly deserve to for all the troubles you have gone through.
