zeek - what kind of cosmetic repairs did you make? As I recall the rear barrel band setup, the screw passes through a slot cut in the underside of the barrel. Unless you cosmetic changes somehow offset the screw travel, ti should like right up. Is the screw bent a bit? Is there any bedding or varinsh or anything in the fore stock channel where the screw passes through? Is the barrel band bent or damaged that you can see?
If you need or want a new barrel band, Browing/USRC sells the Winchester parts and you may be able to obtain a rear band from them. The telephone number is 1-800-945-1392. HTH. Mikey.
