To the point is was pointed out by the two guys beside me at a class.

    Also like HKGuns said, a lot can go into that. If they require one more QC check or one more pass on a piece of equipment, they are getting charged for that. So it will be passed on to the consumers after they finalize how they are going to word it on their web page.
    I've read a few times that Centurion specs a tapered bore on their barrels. Can anyone confirm this?

    It seems like it would take FN more time and effort to make barrels differently for different customers than to make them all basically the same. Two kinds of steel (4150 CMV or 410 stainless), chrome lining on most or all of the CMV barrels and none of the stainless. I would wonder if the mandrels are different for different customers or all the same. But the machine(s) are the same, and getting a consistent product would come from running the same process for all.

    The customer's requirements for tolerances, other quality measures and gas port size may well vary, and hopefully the more expensive resellers have tighter requirements. But I don't see how the input would vary much.

    Never mind, it says so on the Centurion website. I know a few people that have had very good results with their barrels, plus I like the idea of supporting a smaller business.

    Yes, Monty has also elaborated on his CHF barrels here as well. If you're dead set on a CHF barrel Centurion or BCM are great choices, they run their gas ports a bit smaller than Noveske. I won't bother with another Noveske product after the few issues I've had with their products and their totally disinterested customer service. BCM and Centurion will definitely take care of any issues you have, big or small. Rainier CHF barrels may also be good, but no personal experiences, and not sure how they size their ports.

    Don't get too hung up on having a CHF barrel, it's not the end all be all. My next barrel will probably be a non HF chrome lined barrel, if BCM releases a 16" EMW profile.

    I'm not dead set on a CHF barrel, but I've had excellent accuracy with my 18" FN, so the idea of another is appealing. I do like the idea of the BCM ELW barrels, but I'm not sold on light profile barrels, you can't change the laws of physics, the groups will open up when it gets hot.

    I was referring to the Extreme MEDIUM Weight, not the light weight, for the reasons you stated, heat and physics. BCM released a 14.5, but not a 16", just yet. The medium is a bit more meaty than the light weight.

    Cool, I didn't realize they had released an enhanced medium weight barrel. Sorry for the misunderstanding. I might wait for a 16" too. That sounds pretty ideal.

    No problem, easy to miss the Medium vs. Light profile thing, I should have typed the whole name out. I had the same thought about it being just about ideal, on paper at least . Now if BCM would hurry up and release the 16" version.

    Everything needs to be put into context. What are you doing with this weapon? Competition, duty use, paper zombies, Facebook pictures with friends? So having said that, yes the groups are going to open a little, but how much exactly? How much are you willing to allow in order to shed a few ounces?

    I have exactly one lightweight barrel (SIONICS 16" LW melonite) and last October I used it at The Site Training Center in Illinois and when coupled with some Carl Gustav 62gr. SS109 ammo I was getting pretty respectable groups. Good enough that I as able to hit a 12" steel plate consistently at 600 yards.

    Do I care if the groups were 5" or 8"? Not a bit because that is still an easy torso shot on person. And since I am no longer in the military and I am not law enforcement it would be virtually impossible for me to claim self defense at such a distance. Within the realm of reasonableness though, I have a carbine that will easily do it's job at 0-100 yards which is well within the limitations. Had I been using match ammo I probably would have had about a 1 MOA group size (5 shots) based upon on our own testing.

    It will likely see some 3-gun use, with some high round count stages with target distances out to 400 yards. So the ability to rapid fire a full mag or more, and then make hits at relatively long ranges is important to me. That is why I would shy away from a light profile barrel.
