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!!
