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.

I believe the barrel markings will be under the handguards.  Can you remove the handguards and see if the barrel is marked?

Who did you buy it from?

Just checked mine and the barrel marking is under the handguard on the bottom of the barrel. Mine also has the M marking on the receiver.



If the barrel isn't marked CMMG I'd be suspicious

The upper reciever is definitely machined by LAR. LAR mills or has milled recievers for Bushmaster, DPMS, CMMG, Double star, Fulton Armory, Spikes to name a few. As far as I know CMMG has always marked their barrels.
