Radical AR-15, .223/5.56mm cal. upper receiver, barrel and hand guard.  Excellent condition.  16" barrel has an excellent bore, bird cage style flash hider.  The bore is excellent.  Has a full length 20" top rail for sights/optics.  100% matte black finish.  Round ventilated metal hand guard is excellent.  Looks new and would make a great upper on a build project or a top-end swap.
