    To the OP the only CHF barrel I own is a POF G-3 barrel that is waiting parts to finish the build. My LMT still has its factory barrel and I have no immediate plans to replace it. I will probably pick up a CHF barrel later on when I am fairly certain that I am at least half way through the LMT barrel life first and then it will be stored away until the day it needs replacement. If it is between a CHF barrel and having the extra $$ for a good duty optic pick the optic for sure. There are plenty of good mil spec 5.56 chamber , 4150 cmv barrels out there LMT being a good example BCM being another.

    CHF is a very European process. It was the Germans that popularized CHF barrels to make machine gun barrels of good quality, faster and cheaper for two reasons

    1: Machine guns burn out barrels faster, obviously

    2. When someone is bombing the shit out of your military industry, getting barrels made fast is sorta important, because you never know when something explosive is going to crash through your roof.

    We have plenty of beat to shit, shot to hell M16A2's in our armory. The last one I shot still makes scary tight groups with no effort.

    CHF barrels are just a choice. Options are good, but many believe and have been convinced that CHF barrels are something they actually aren't when compared to a standard Colt M4A1 barrel

    In LMT's 2009 catalog, they claimed a barrel life of 10,000 rds average for their CL barrels. There is a thread about Noveske Barrel life here: https://www.m4carbine.net/showthread.php?t=54614
    It has info on how long CHF barrels last.

    From your last post I am not sure that you have actually made a decision yet, so maybe this will be of some help. I own both a BCM 14.5" std. (car. gas) and BCM 16" CHF (mid. gas). Using a host of different ammo (including MK262 clone handloads) I've been able to get the 14.5" down to right at MOA, 16" CHF I can get down to .70-.75 MOA. Groups were not shot on the same day and I don't keep weather logs, but I can say that both days were similar temps without any crazy humidity or precipitation. Both use FF rails and Aimpoints, T-1 and M4 respectively. This doesn't mean that one is more accurate than the other in respect to the rifling process since there is a difference in length of barrel, gasport location, size of aiming dot, different triggers etc.

    So if I've managed to confuse you any more, your welcome

    Basically, if the barrel contour you want is available in CHF and the extra $100 isn't an issue, go for it. If you are going to settle on a barrel contour just to get the CHF, then in my eyes it isn't worth it.

    I was looking into CHF as a means of "preventative measures" if that's even the right term to use. I figured I should just go ahead and get the new upper with it now and not have to worry about replacing a barrel anytime in the near future. But then again if the average barrel life is 10,000+ rounds I'm starting to think I'll be okay with the regular CL.

    OP, define your purpose & requirements and select equipment that meets them. If the advantage of CHF barrels meets your requirements and purpose then that's what you should be buying. The definition of quality is adherence to requirements, not goodness or elegance so don't fall into that trap.

    I think that's the best way it's been put.

    Those interested should speak with Mike Rock.

    CHF has more densely compacted grains so it's stronger in many respects. It also has better wear resistance.

    The substrate (underlying steel) material will be more stable than cut rifling and SHOULD offer a better grade base material than cut rifled material.

    BTW, ferritic nitrocarburization is better than hard chrome: no geometric distortion, better wear resistance, better salt water corrosion resistance.

    Combine the two: CHF and Melonite.
