All Colt's M4 uppers have a raised "C". This is to prevent someone from just stamping it with a "C" stamp. I have seen carriers and bolts that have been engraved or stamped "C" and "MPC" in attempts to fraud. Also it would be nice to see a pic of the wrap Because some of us know what authentic wrap and labels look like.

Kvn555 carriers, bolts along with other internal parts are usually marked by a stamping if marked at all. Colt's produced many internal parts with and without stampings and engravings. Because of the relative ease of stamping a letter makes spotting forgeries even more difficult. Whereas an upper receiver has raised markings. The keyhole mark denotes "Cerro Forge" where the stamped "C" can mean anything. Another practice is for a part to be switched out before the purchaser receives it, for example replace upper or build up from parts using mixed authentic and counterfeit. Again the question has to be asked "where did your item come from?", how was it packaged, and what supporting documentation accompanied it?. Contact Colt's ask them if your "C" stamped upper is authentic. Truly this market is "buyer beware".
The problem comes from the seller not wanting to take the item from the package, so we cant get a look at the markings.
We will need that first. But that's his call, and I respect the decision he makes concerning this.
