6920 Upper Q

AR/M4 AR General Discussion

Hey Guys, quick question…

How can you tell if you have a 6920 upper? I bought an upper recently that I was told is a 6920, with a rail that was installed (not the stock handguards). The barrel has a C MP 1/7 NATO stamp on it and there is a “C” stamped on the Bolt and H on the buffer tube. Thats about all I can see tho… any help appreciated.

usually on the right side of the upper receiver near the charging handle there is a forge mark. next to the forge mark there should be a C stamped into the upper designating colt. as far as determining that it is it a 6920 upper I do not know how to determine that from other colt uppers.

Based upon what you have described it sounds legit.
