    I always assumed the increased barrel life was attributed to the thicker chrome layer FN was putting in the barrels, not the actual barrel steel...?

    I also assumed that having a thicker chrome layer would also inherently make a barrel less accurate...?

    I admit to having not much, if any, experience with the science of barrels and metals past casual shooting.

    Not entirely due to thicker chrome. Read up on Steyr, Glock, Sako (TRG) etc barrels. You might find it is actually not just for "cheaper" or "quicker" production. You actually end up with a more quality controlled product with ChF, better steel characteristics, etc.

    I think it's pretty well documented, companies like FN with the SCAR went with CHF barrels and that platform has been extensively tested. FN touted a 30k barrel life in the 17s (albeit .308 is lower velocity), most companies that produce CHF claim 20k barrel life in 5.56 vs. button barrel 6-10k barrel life.

    Either way I wouldn't lose sleep over it. If I was to pick I'll take CHF, but I would lose any sleep buying say a Colt 6920 where your only choice is to government profile button barrel. When the barrel is shot out and accuracy/velocity degrades, have the barrel replaced.
