In looking around a bit, I've become curious about the markings one would expect to find on a Colt A2 upper receiver. Here is a shot of the upper from a 6520 bought NIB:  And here's a shot of what I purchased as a new 6520 take off upper:  That one has what I believe is the Anchor Harvey forge mark, but no C. Following are some shots of Colt uppers without C markings: 0713206 0713406 0713506 And some with C markings: 0712304 0709302 A quick perusal of NIB 6520s offered on Gunbroker where there's an appropriate photo shows the C mark on all. So, does Colt produce completed A2 uppers without the C mark? |

The upper picture shows Cerro Forge markings. The C and the keyhole. I THINK that the C on that one might mean that it was made for Colt, by Cerro. I could also be quite wrong on that detail. Flattop uppers with the keyhole mark are also Cerro Forge. I have one. CJ |
