I've got a 5-22x50 NF on my rifle mounted w/ Leupold Dual Dovetail rings and bases (like every other rifle I have). I'm looking through the NF manual and it specifically says don't use dovetail mounts (I know I should have read it first). How big a deal is this? I really don't mind getting some new mounts if I need to, but will it make any real difference on a hunting rifle? If I do need new rings and bases, could you recommend some good, light-weight ones? Thanks.
