I wish Ruger would come out with some off-set rings for their #1 because getting many modern scopes far enough back on the #1 is a problem.
Not just the typical 5/8 to 3/4 inch offset, but rings made JUST for the #1 that give about 1.5" of offset.
Another thing they could/should do is to make a quarter rib that is just for the #1 and comes all the way back over the top of the receiver, (like the one GPS Fan shows in his pics) so as to give us all more options to set our rings. The ribs they make now fit barrels in their M77 also, but don't give that extra length to the rear that is so helpful on a #1.
