Hello,
Just bought what was advertised as a NIB CMMG M4 Upper. The upper has a "Keyhole" casting mark, back of the take down lug is engraved "L" Front of the recivers, by gas tube, engraved "M" Picatinny slots engraved with T series numbers. No other makings on reciever. No markings on bolt, carrier and barrel. FSB has casting marks and stamped "F" How do I know this is CMMG ? Thanks Nitro PS: Box and Bag unmarked. |

Quoted: I believe the barrel markings will be under the handguards. Can you remove the handguards and see if the barrel is marked?Hello, Just bought what was advertised as a NIB CMMG M4 Upper.
