I have 8 right now. Never had an issue with any. Been thinking about a Bartlein, but just to try somthing different. One thing I do like about Shilen is I can usually get them fairly quick through "The Barrel man. " good prices and service.Google " The Barrel man" not an endorsement but he is a great guy to deal with . Never had a problem. These guys have been building barrels for a long time. Regarding fluting I think they say on there website that if you flute it, your warranty is void. Other than that they shoot if they are screwed on right. Never had a smith tell me not to use one.
