Tried to clean my compensator on my Black Mamba today and had a devil of a time.
I tried "The Dip" to no avail. Then I used my Voqluartsen Lear Pulverizer and it got most of the lead out but I didn't realize how much was in there.
I finally took out my brass punch and hammer and went at it gently tapping until too large pieces of lead fell to the table. I was then able to finish it with the Pulverizer. Good tool. I just don't have the strength to use it anymore on the first pass.
