. I’ll keep going until the patches are almost white. You know, when you're wiping your a$$ after taking a sh!t, you don't stop wiping your a$$ when the toilet paper has slightly less sh!t on it compared from the last wipe, you keep going until the toilet paper is pretty much white and that’s exactly how I treat my guns when I'm cleaning them. Sure it uses a lot of patches but I don't care, it needs to be clean. I’ll do the same for the gas tube as well and by the time I’m 100% satisfied, you could take a white glove, wipe it, and the glove will still be white.
