Correction: Every new Knight has a green mountain barrel. My three Knight's are pre GM. Some of the barrels on Knights in the latter years they were making extremes (I don't mean the current company) had some really badly done crowns. I know sabotloader redid his and so did some others. Why t/c couldn't spend a little extra and get their qla centered on the bore is another mystery to me. Too much haste in production.
