M-Pro 7 copper remover. Does it work?

[jaygorski]

Got a gallon today, cleaning the carbon out now, looks like it's clean after one patch, not sure how much copper is in there now, wife and I could see copper sitting on top of the lands Tuesday evening before I put 12 rounds thru it Wed, I'll shine a light down and see if anything is visible. I did remove most of it after I ran a patch of Sweet's tuesday night, didn't see any more copper.

Were there more than 12 rounds since the last cleaning?

FWIW - I've tested MPro 7 vs Boretech C4. After several patches of MPro, brushing with a bronze brush and finishing with dry patches, I ran one patch wet with C4 - lots of black stuff.
As a carbon remover, MPro is relatively ineffective.
I have no experience with the MPro copper remover.

I use MPro7 stuff on pistols where cleaning is less important. I've never used the copper remover.

Good point. I use MPro 7 as a general cleaner on my AR's - does a nice job on the bolt carrier, bolt, etc.
