I'm cleaning my AR and am planning on going to the range later today. It's a CMMG upper with a chrome lined bore that I purchased Brand New. It's never been fired.
I started out by running hoppes powder solvent and then some dry patches, followed by hoppes benchrest and more dry patches, then an oil patch and a dry patch. Both Hoppes products got some dirt out and came out looking green. I then looked in the bore and saw a little crud in there so....
I went to my bore brush and ran it a couple times to get whatever is in there a little more loose and ran an oil patch which came out black. Ok...
So I went back to the Hoppes solvents for another round and finished up with some more oil, and still saw some crud in there, so...
I went back to my bore brush and ran it 4 times and the next oil patch came out black, so...
I went through the whole process again and decided to run a wet patch of Hoppes Benchrest and let it soak for a few hours, so thats where I'm at now. I honestly wasn't expecting that much dirt coming out of a new bore. Am I doing something wrong?
**UPDATE** Every time I run a bore brush it seems to loosen up debris so I've been doing that for like 20 cycles (1 pass with bore brush, 1 pass with patch soaked with Hoppes 9 Powder solvent) and the patch has been coming out with a good amount of grey residue every time. Is there something wrong with this? I don't see why it shouldn't be clean before I shoot it for the first time, and a couple people have posted replies about a bore preserver coating from the factory that you're supposed to remove before shooting. Am I on the right track?
