How does one deal with this? I've put some rounds down it, and thought they cleared it out, but after cleaning, it's still there. I'm guessing the gunk from shooting covered it up. It doesn't really look like it's to the point of pitting the steel, but I don't know for sure.
I can see rust from the muzzle end, and the chamber end, so I assume it's like that all the way through the barrel.
The barrel is a Colt 9mm AR barrel that my uncle found in his "spare parts bin" in his basement (see a couple posts down. I forgot to mention this was unfired before I got to it). So I threw together a 9mm build with it.
How should I deal with this? Put more rounds down the pipe? I've only got a few mags through it.
I've used foaming bore cleaner and CLP (with brass brush/jag/patches), and still no luck.
