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.
