I purchased this rifle from a dealer a number of years ago, and at the time it was advertised as a Winchester 70 action with a Ruger barrel; I thought that was kind of interesting, so took a chance, and this is what showed up... It's a Winchester 70 Classic late G-prefix serial action nicely bedded in a Pacific Research fiberglass stock, and with what looks/feels like a grey/blue teflon paint finish.
The barrel is what I'm curious about since it was advertised as being a Ruger, although I'm not convinced. I imagine the shank/threads would have to be fairly close to make it worth the effort to use on a Winchester action. The barrel is ~ 21", and I measure the twist at roughly 1:9.75", which is close to the 1:9.5" I've read was used on some Ruger 7x57s. The 7x57 stamp is the only marking on the barrel and perhaps it's close to the factory stamp Ruger used (see last picture) with some shallowness after polishing/re-profiling the barrel.
Addendum: confirmed this is a Ruger barrel as shown in the additional pictures posted on this thread:

The front sight is another oddity as there is no provision for a rear sight on the barrel, so I imagine the owner/builder was planning to use a receiver sight mounted on, or instead of, the scope base.
Total weight is 6lbs 8.5oz as shown.
Hope you enjoy the pictures, and if anyone could tell me more about this (on the off chance you recognize the rifle?) I'd be interested in learning more.
