That's good to hear, even though it's more than I would spend on one for a factory gun. I run a few patches thru them after say 60 - 75 rds , and only use wipeout / patchout. After reading a few threads on the subject I'm wondering about carbon build up since patchout doesn't remove it, and as I said I need to spring for a modern setup that I can clean with without damaging my rifles.
