One thing to remember is in this modern world, companies are bought & sold like, well, any other 2-year disposable items. It is all about branding.
So while I don't know much for sure, the Weaver's of the mid 1990s are not the Weaver's of today. Whether or not the internals are the same, I dunno. They are made in Japan, probably to the specification of "Weaver." Whether or not the materials, assembly techniques, etc. have changed, no one knows. For sure their repair service has changed, and not for the better.
As far as I know, Leupold still retains control over more than their brand.
I do use Weavers. They have all been fine, except for the one that quit on me. I suppose I could have it frozen, always an option with any scope.
I wouldn't worry over much about brightness. We don't shoot benchrest at dawn or dusk. Having sdaid that, some people feel the new Leupold's clarity is better when the mirage is running. I dunno, doesn't make sense to me, but optics is all voodoo to me too.
As to the rings, I use Kelbly on short-range rifles, because of the weight. I do use the Burris Z-rings on a couple long-range rifles; they are fine, a bit ugly perhaps, but they are also heavy. If you want the Z-rings (best price probably Brownells with your smith discount), weigh them first.
With all those words, Wilbur's post (#2) gave about as much *information* as we know for sure.
