I already have a set of NF ultralite .885 rings and a NXS 5.5x22x50. I will be using the sunshade and Butler Creek Scope covers. Going to be putting this setup on a Surgeon 591 action mounted to an MTU contoured Krieger. I'm starting to think the .885s are going to be too short. Problem is the action and barrl are on order thus I can't actually peice it together for evalution. Anyone else have a similar setup or knows what is the shortest possible ring I can use? Can anybody shed some light on this?
