New pics added after cleaning shots. Little past half way down. |

I'd call the place you got it from and ask for a replacement. That looks terrible to me.

Yea i never seen a new barrel like this ever. Not sure if anybody else seen a barrel like this before. Is it possible it has some kind of special coating inside?

I'd be more concerned with that nubbin looking thing on that first pic. Have you tried to pass a swab down it to see if it comes out easily with some hoppes or something

Is it RUST or a RUST PREVENTATIVE? Like SP-400 corrosion inhibitor or a cosmoline or similar?
Try cleaning a small portion and see how it looks. |

Looks like dried cosmoline.

The edges seem a little too rigid and harsh to be rust. It almost looks like some kind of film unless they flaked in perfect-edged pieces. Regardless, that little metal imperfection also seems a little sketchy.

It's been 5hrs, did the patch get stuck?
I'd run a patch through it and go from there. |

Looks to be some kind of corrosion inhibitor like Linebacker or LPS-3.

This is a common occurance. The brown color is a preservative to prevent corrosion, but unfortunately is a similar color to rust so people tend to freak out. It's commonly used on all kinds of AR parts.
Denatured alcohol will take it right off, or will clean off with most other cleaning solvents. It is NOT a lubricant. Failure to clean it off a new gun or new parts before shooting is a common reason for malfunctions in new guns. |

JSE got flooded this past spring /summer. Badly.
I do believe it is a corrosion inhibitor, I would clean a small portion of it and inspect. They literally have/had hundreds of stock bbls on hand. Have to prepare them for long storage somehow. Again though, whats the story with the first pic of the muzzle? What's with the ring around the outer edge? Like it's a sleeve? Tig |

Tig It is just the way the barrel end got machined, it looks like a sleeve due to the lighting of the image. Myself, instead of sitting around wondering, I would dip a couple of patches in kerosene and run up the barrel from the receiver end and you will see as it softens up, it will start to come out of the barrel. |

Take two or three Q tips and rubbing alcohol and swab out the muzzle then see what it looks like.

I'd send those pics to the manufacturer because there is some pitting and they should stand by their product and replace it with one that isn't. |

I'm seeing the pics on a smartphone, OP . BUT I DONT LIKE WHAT I SEE EITHER!
Personally, I'd send that turd back to MO. Plenty of sources for a quality bbl out there, and that one isn't, imo. If that barrel was "cleaned, inspected, coated" prior to shipping to you, somebody needs a kick in the ass. |

Well, I am going to have to give in and say, get an RMA number from them and move one, looks like it might be an old barrel that set a bit too long and may have had a small amount of moisture under the coating they put on it. |

Rem Bore Cleaner is a mild abrasive which physically scrubs out fouling from the bore. While it works great on patches for powder fouling and the like, it will not be very effective on a thick greasy or solidified protectant product.
Scrub the bore out with hot water and dish soap, or denatured alcohol like I suggested before and see if the brown gunk doesn't come right out. Polar solvents are much more effective IME. Small parts like LPK's and such I usually just put in a can and let them soak in alcohol overnight to dissolve all the gunk. Another thread a while back of the same thing as an example: http://www.ar15.com/forums/t_3_118/692075_NEW_rusty_barrel_from_Aero_Precision__.html |

OP has done all he can, that thing needs to be on it's way back where it came from.
The brush would have taken out any soft coating. |

Please look at this whole thread. Rust or whatever seems to be gone now but what i'm left with seems to be some pretty bad pitting in the barrel.
