I lap all my rings, but i have a new titanium NF Uninmount, befor i get my swull on and bust a sweat lappin this guy, have any of you guys lapped titanium rings or unimounts befor? they do align, but like to have more surface area touching my tube, i have lapped my Knights rings and a few sets of my Leupold MKIV rings, all needed it, and i figure i might as well do it right if i'm putting on a $1600.00 scope.
