I just bought a Winchester Classic Stainless 375 and it has not arrived yet. I want to put a NECG rear sight on it and I need to know the barrel size. I am sure it is probably .930 but I want to be sure. I want to get the sight ordered so I can have everything ready for spring bear. Any help would be greatly appreciated.
Thanks

I would wait until you get the rifle so you can be sure of the measurements.

I just measured mine for you. The barrel at the front edge of the rear sight is .950 diameter. at the rear edge it measures 1.070 .

Thanks
