I've have a Colt AR, it's obviously a put together lower/upper have two finish colors.  Is there any way to determine if the upper is actually a Colt, if someone in the know could tell me to look for stampings/markings and what they are I would be gratefull.  Thanks Pluckmaster.

Just because the upper and lower colors don't match doesn't mean it didn't come from Colt this way.  When they switched anodizing colors, there were a lot of "mismatched" uppers and lowers coming out on the carbines.  Some were really ugly.
