Hey guys. I just purchased my first nightforce. Nightforce NXS 5.5-22/56 with MOAR reticle. It's going on my remington 700 5R .308 milspec with one piece nightforce 20 moa rail. What size rings do I need to order to clear the barrel but get it as low as possible with butler creek flip up covers? Also any certain ring reccommendations you guys can think of? I have an ACI mounted on the rail but can mount it on the scope if need be. Thanks guys.
