I have one piece rails now on all but just 2 rifles now. Just simpler when I want to do scope rodeo and such and really no down side aside from a couple fractions of an oz. Loading and unloading is certainly not an issue here for me with a one piece rail. Granted its not an NXS on there so maybe that part would be different.
Though putting the SHV 3-10 or NXS 2.5-10 I would be well under 7 pounds, but for this rifle I am ok being at just under 7.25 pounds. If I want to go lighter I have other options.
