I ended up going with a two-tier system. My "inside voice" was a Mk18 CQBR w/ an eotech and a can. My "outside voice" was a regular, rack-grade, plastic-stocked M14, to which I added a Millet 1-4x scope and couple of small sections of rail for a grip-pod, a light and a PEQ. Stoked it with M993 AP. It consistently shot "minute-of-hajji" as far as I could shoot. It was my "go-to" piece for almost everything short of a knife fight.
