upon breaking down my AK to install the new spring, I noticed there was a very small amount of residue closer to the hopup unit. Little to none at the muzzle end. One swipe with a cleaning rod/strips of a rag and it was clean.

I have a feeling that the coating that Mad Bull uses helps prevent residue from building up and is slick enough to allow easy cleaning.
