Cleaning with a chamber brush is always recommended. However, the rest of the advice is unacceptable from a manufacturer. There should have been an offer to replace or repair it, with shipping on their dime.Quote:
He told me to take the chamber brush, lube it up real good, attach it to a cleaning rod then a cordless drill and lightly run it for about 10 seconds. Then take some emery paper, wrap it around the bore brush and do the same for about 10 seconds. I don't know how comfortable I would be with this and can't find any information on how to do this online.
