Have a question on Ruger rings. I got my VBBZ, came with the standard Ruger rings that match the gun, with Torx type screws supplied. I put a Nikon 4.5-14x AO silver shadow on it, with the rings mounted correctly (lug to the front). I tightened the top rings up in sequence untill as snug as I could go with the supplied "allen" style torx wrench, and afterward I have about a 1/32" gap between the top and bottom rings. The scope is solid, with no movement or visible gaps between the tube and rings. Is this normal for a Ruger rimfire? My .308 M77 MKII has Ruger rings and shows no such gap, with a Leopold VXII 3-9x on it. What gives? I could use a torx screwdriver and tighten them some more, but I sure don't want to kink the tube on the Nikon. Any advice would be appreciated.
