Was looking over some of my rifles yesterday when I noticed what looked like rust developing in the bore of one just forward of the gas port.
I immediately cleaned it, but it is still there. At the moment I don't have any strong solvents that that are designed specifically to remove copper fouling (only MPRO7 and Kroil)...Im leaning towards copper fouling as even with a copper brush i was not able to remove it..I'd assume if it was rust than the brush would have gotten rid of it. Crappy cell phone pic attached. Its the one on the right..This resulted in a massive Christmas Eve cleaning of many firearms...

Whoa! Chill out, it's copper fouling. Now don't go crazy with brushes and cleaning rods. You could damage your barrel. Instead order some Patch Out. When it arrives just run some Patch Out through the bore and let it sit overnight. The copper will be gone and your barrel will be clean. |

I just ran a patch soaked in kroil down the barrel followed by a brush (brush only goes down the barrel once), and I use a bore guide and a J dewey coated rod. Generally I can tell the difference between rust and copper fouling, but I think what tricked me is that there was a layer of dust in the barrel that made it look like the fouling shown here had almost like 3 dimensional appearance, and additionally the fouling in this picture is in patches. Typically I've seen it where it is in streaks. Bright side of this is it forced me to go through and spend Christmas Eve oiling my Garands..most of them at least. 12 down, 2 to go. Next up are the carbines M1903s and A3's/ |
