I have a grey matching Nodak Spud A1 603 upper mated to a partial fence xm16e1 lower, triangular handguard, aluminum CAR stock (until I can make a real 607) and a 3 prong flash hider, that will replace the pinned and welded xm177e2 flash hider once the stamp gets here.
EDIT: I took the AR10 to the LGS to show it off, and ask about the bolt catch, and the gunsmiths asked me how many rounds were through it.....
