Diesel and a brush. Or WD-40. Unless you can find REAL mineral spirits and not the crappy substitute that everyone sells.

Heat it up with a heat gun & it will drip right off.

I soaked it for an hour in mineral spirits and scrubbed some more it did nothing. WTF kind of grease is FN using that this difficult to remove?
I emailed the dealer I bought it from and he even sent me pictures of two other barrels he had in stock and they were all like this |

Naptha.
ETA: It may actually be rust. Try rust remover? |

Maybe try a stronger solvent. Lacquer Thinner ? Paint thinner is kinda mild.
I would spot check its results prior to going hog wild. And while this might sound stupid... try some soap and water, or Denatured Alcohol.... Maybe FN figured out some kinda "green" product. |

Try some brake cleaner. I used it to clean up some gunky NOS FAL mags. Just don’t do it inside the house…your wife won’t be happy about it

Denatured alcohol or acetone and a stiff nylon brush.

Update: It took a ridiculous amount of scrubbing with CLP and a wire brush but I managed to get most of it off
Originally Posted By coldair: what barrel and where did you get it? I am thinking of SBRing one of mine View Quote It's a 10" factory barrel. TheArmories.com had the best price I could find and they shipped fast. Also responded quick to my email about the tough grease. Wouldn't hesitate to buy from them again. Prepare for sticker shock though if you've never looked into what factory SCAR barrels go for.. |

Being coated in grease or oil is not a 100% guarantee against rust. Moisture can still get through it. Seen it many times buying new OLD stock parts (not just gun parts, but automotive parts too) I have dealt with lots of old dried grease and oil for years. Some tough, some easy. If acetone or carb cleaner and a tooth brush will not take it off, nothing will. I have never has a dried grease or oil not come off with either of those. If it does not come off with those, it is not grease or oil. Old locktite can be a bitch, as well as other substances like it. |

Not all of it was dry, some of it around the front sight was still a little sticky like cosmoline. What I think happened is whatever preservative they are using is staining the metal. I threw out my packaging but you can see in the gunbroker listing how nasty they come: https://www.gunbroker.com/item/1032951631 |

I noticed something funny today, even the example on FN's website seemingly has some of the same stains visible on the gas block: https://fnestore.com/scar-16s-10-in-barrel-assembly

IME, on 2 nib FS2000s and 2 nib Scars, all of them were like that. I assumed it was rust.
