The Bolt is marked 7.62. The Carrier is marked with a "B" right next to the Bolt removal pin. I have looked everywhere on the net and can't come up with who manufactured it.
The bolt appears to be coated.....black not chromed. I believe it to be a Colt BCG but can't come up with any information.
Is the 7.62x39 BCG as supplied by COLT with this upper any different then the standard 5.56. I know the Bolt is specific to the 7.62 due to the size of the brass.
Just trying to identify the manufacturer. Any help would be appreciated.
