Auto BCG, carrier appears to be contract (1b1b6 stamped on it, registered to Tool Craft of North Carolina), Bolt is FN. Charging handle. Colt 11.5" Upper. KnightsRails (no rail covers). Minor finish wear, mostly on the rails., but again, unfired, internals look amazing… Open box special. Let me know what you have to trade for.
