Since an American, Ed Shilen got involved with Bergara barrels the quality is excellent.there M/L barrels are one of the best made as far as accuracy is concerned.T/C barrels like the one on my triumph will shoot excellent also, after you clean them up and work the rough spots out.as i have said in the past, if a person wants a barrel that will shoot any type of bullet accurately ( full bore lead and non lead and saboted bullets). then a knight with a GMB is the way to go.
