Standard Weaver mounts for the Winchester marked rifles are #46 front and rear. If those are too crowded, #402 extension bases will help with eye releif.
I got tired of fooling around with high rings- they don't work well for me on this rifle (admitted stock-crawler

) I took one of those 402 bases, and milled a second slot into it- works like a charm, and I have my 4-12X 40mm A/O in Low Weaver Rings- and no more bolt handle scraping the eyebell of the scope. I know I'm taking a chance with only 2 screws holding that big scope on, but it sure beats what I was doing before! I handle the rifle carefully, anyways- it's my baby...
