tumbling media in the axis action threads??

Hi all, I'm new to savage shooters and new to Savages. I found out through an 80% at lower and a mosin nagant I enjoy making something from nothing. This is my first venture making something from something but after I bought my donor axis I noticed all kinds of tumbling media impregnated in the barrel and barrel but threads? Will thus mess up the threads? How do I avoid complications from this? Any help or feed back would be greatly appreciated! Thanks!!

Just spray it with solvent and wipe it down. I use Kroil to remove the glass bead media and anti-seize from factory barrels/actions and then brush on a little bit of moly grease at assembly.

it's left over from the factory. Has become very common and have seen it pretty much every time I've removed a factory barrel. Threads should be fine just clean them up before spinning a new barrel back on.

Thanks guys glad I'm not the only one who's seen this

They seem to be laid on thickest on my Axises, but even my 11 had some.
