I purchased this firearm from a local gun store and brought it home for it's first cleaning. I'm using hoppes 9 lube and it's not taking to the bolt carrier group. Any advice? Is it packing grease? A bad finish? It's tearing my cleaning wipes when I use it on the bolt carrier. Thanks for the advice. If it's normal I've never seen a part as rough as this. It's on a majority of the bolt carrier.
