So I've watched numerous videos regarding barrel break in. Some say to swab the barrel after every round fired up so a certain number of rounds. Others recommend after every third shot. I just replaced my factory S&W M&P barrel with a Bear Creek Arsenal. Nothing super special, just a .223 Wylde.https://uploads.tapatalk-cdn.com/201...6a2f4bcab3.jpghttps://uploads.tapatalk-cdn.com/201...97ab7e6473.jpghttps://uploads.tapatalk-cdn.com/201...ec698dfb8b.jpghttps://uploads.tapatalk-cdn.com/201...c44e0f5dfb.jpg
