Before S&W took them over they had some of the best barrels made. Then after the takeover they were like Marlin during the "Remlin" period for about 5 years. You had around a 60% chance of a good barrel. I think they are coming out of that but that QLA is just an unnecessary gimmic in my opinion. I miced her Impact barrel and the recess SEEMS to be on center. I may throw some connies down range to see if it will shoot them. If not then I may cut that QLA crap off and put a 11* crown on it.
