Well marked, solid Colt upper
Mine came with cage code and M4 on upper, cage code and "C" marked barrel. Bold carrier light C mark. Bolt has strange A mark. Overall solid buy. I bought to go on a roll marked M4 Carbine lower I've had for awhile. Great pricing as always from AU.

Better than the photos
Very Nice upper, swapped it for old Nam Era A2 stock lower that had some years on the upper. I compared them on a chrono the New Colt Upper was 100 fps faster with same ammo. Very tight chamber for a 5.56 and no issues feeding etc. Shot 1" groups with a 12x scope. 100yards. For those that care on Markings Barrel has the Colt Cage number 1/7 nato 5.56 Upper rear has Colt cage and Square on rear right side Bolt carrier has dotted letter C on it Bolt has faint MPC on, almost invisible. Colt quality is still there in the LE series

Arms unlimited are the best
I bought few things from Arms unlimited for many years and they are the best, I highly recommend buying from them. They have the best customer service and very fast shipping and for sure the best prices around. I trust Arms unlimited and will always buy from them. The Colt Ar 16 inch upper is the best quality and so accurate. It comes with the bolt and you will be very happy with it. it can shoot 223 and 556. They use this upper at the military as far as I know.

Nice Quality Upper Assy
I wasn't expecting this level of quality from the 'new' Colt MFG. The finish was actually better than the older Colts I've seen and came with the proper Cage Code markings on receiver & barrel. The BC was engraved "C", but sadly no markings on bolt. I couldn't buy the parts to assemble this upper for what AU is selling them for.
