The following are all forge marks from genuine Colt upper receivers that I've purchased.
.... Colt proof marks 
.... Colt bolt marks. 
..... Colt barrel stamps 
...... Add your pics of additional upper receiver forge marks (and other identifying marks) that you know FOR A FACT are genuine Colt parts. ... |

C MP C barrel stamp. This stamp is on the under side of the barrel (the top and sides are unmarked).
This dates to the brief period from about '68 to '69 when Colt was chroming the chamber, but not the bore (yet). This was on a government-supplied M16A1 obtained by a police department under the 1033 program (I converted it to semiauto only for the department). The upper receiver was devoid of the Colt "C" or forge markings, like the 733 upper receiver posted above. It had the teardrop forward assist and did not have a brass deflector, though.
