I have what was described as a factory assembled Colt upper. It has a Colt flattop upper receiver, a 20-inch gov-profile Colt barrel, a full front sight, a bayonet lug (I think) and a flash supressor. I also have the carry handle which came with this upper.
Can anyone help me determine what this upper is? It was mounted on a R6551 Sporter Target lower when I bought it as a complete gun but I do not think that this is the upper that came with the lower from the factory but I could be wrong?!?
I looked at the old listing at....old.ar15.com/manufacturers/colt/modelNumbers/
with no luck.
p.s. I am considering selling this upper and that is why I am trying to ID it and determine if the original seller was correct that it is a factory assembled Colt upper.
