Have you tried acetone?

If it were me I would probably leave it alone, just put some CLP on it and call it a day. However, you could try Hoppes #9 or my personal favorite Breakfree CLP. Apply it, let it soak for a few and gently scrub it with a nylon bristle brush. You could try some of the more aggressive solvents out there but I don't think it's needed. If you run your rifle hard enough over time it will probably wear away or even cook off
 . I hope this helps.

Sure you didnt lean a hot rifle against a nylon gun case, sling, cordura, carpet? looks like melted nylon.

Was that by chance the underside of the barrel as it layed when you may have possible applied more mpro than needed AKA it could be a dried up droplet that never dropped.

Thanks for the responses! I haven't tried acetone, but that might be worth a shot if it doesn't damage the phosphate coating. It's actually towards the top of the barrel so I don't think it's a dried drop though I do think it would have burned off by now. I may just leave it as is and see if it bakes away by itself.

I would not use anything more abraiecive than 0000 steel wool to try to rub it off with and i would start with a plane cotton cloth.

It looks like a cosmetic defect in the finish that attracted some residue or you leaned your barrel against something plastic. My advice would be to clean, shoot, and enjoy the firearm as much as possible.
