I have a 556 LMT CQB that shoots well. Usually well under 1 moa. But not my LMT MWS CL 16" that I bought when they first came out. 5 shoot 100 yards with168 grain FGMM or my 168 grain SMK hand loads that shoots well in my early LaRue OBR or AIAW. Best I could get was 1.5-2 moa. Have a Nightforce...
