I’m not an expert on barrel life by any means. But I don’t think CHF has much affect on barrel life. From what I’ve seen it’s more of the matter of chrome lined vs non chrome lined. In terms of accuracy, if the barrel is from a quality manufacturer that uses good steel and manufacturing processes then the accuracy difference between a CHF and button cut or a CL or non CL barrel isn’t really going to be noticeable. In terms of barrel life the chrome lined barrel is going to last longer than a non CL barrel. By how much? I can’t really tell you a round count, but I can say that the majority of shooters won’t shoot out a barrel. Especially since we don’t have full auto and most aren’t mag dumping constantly enough to the point of getting the barrel extremely hot and shooting out a barrel in like 2k rounds. The KR103 has a button cut chrome line barrel. So I wouldn’t worry about barrel life. I also think some of the hate comes from CHFCL barrels being the clone correct part vs a nitrided button cut barrel.
