Bought this used on the EE, unknowed round count- barrel looks good to very good- parked M4 feed ramps. Flat top upper marked C and keyhole with M4 over gas tube, white RAS markings. Barrel marked (C) MP 556 NATO 1/7, no flash hider- barrel is threaded,front sight is not F marked, no sling mount. From what I understand the barrel is from an M4A1 or A2 upper and the receiver is from a M4A3. Includes LMT A2 buis. Slip ring and receiver have a few scratches, barrel very good. Comes with non Colt carbine handguards. of course no BCG, no ch included. Can email pics.
