Be careful to make the wedding band minimal, otherwise it will look like a two-piece barrel with a pipe fitting between.
Also for proper eye relief it is best to have the rear scope base on the top of the receiver although Ruger doesn't know this.
My smith was going to machine the quarter rib within the Lilja replacement barrel, but after discussing the scope issue with Ruger 1/3 we've decided it will be machined from bar stock so we can allow it extend over the receiver. That will required it to be sweated on, but the number 1/3 complicates a few things. Wedding ring will be quite small because I've seen the big ones and it looks just wrong IMO.
Don, I'll look at the other scopes. I've got a 2x7 on my little Remington Mannlicher. Don't even know its there its so light and compact. Leupold also makes a compact 3x9 Ultralight and that's a consideration. Agree smaller is better in this case.
