It was the Basil Haden Toast tonight, neat and on the rocks. Buddy and me polished off half a bottle telling hunting, shooting, and gun stories. Good times!
@HighFeedSlowMag, sorry for the delay getting back to you . . . the center-to-center dimension between the two rings is 3.200" (81.3mm). Hope that helps.
I’ll put some calipers on it when I get home this afternoon and get you the exact dimensions. It had a S&B scope in it with really large turrets and had plenty of clearance. The pictures here in this thread might help...
