Hi all , I need a set of rings and a base for a Rem SPS in 7mm magnum.I am thinking about a Nightforce 20MOA one piece steel base and a set of Ultralite rings.The scope I have for this rig is a NF 5.5-22x50. I want the lowest set up I can get away with but still need enough room for some Butler Creek scope covers.Would a set of .885 rings work for me ? Any comments greatly appreciated.Cheers Steven
