As Lasher said above. Harrison Beene sells some of the best barrels in my opinion. Nitro-Carburizing is a treatment, not a lining like chrome. This is what he has to say here http://ar15performance.com/faqs
"Why do we sell (Melonite) treated barrels instead of chrome lined barrels?
Nitro-Carburizing, Melonite, QPQ is a heat treat process for barrels that harden the barrels to apx 60 Rockwell so they last longer, are more corrosion resistant inside and out and it also decreases friction in the barrel which can increase velocity and cut down on copper fouling. Chrome lined barrels can decrease accuracy as it is a built up layer inside the barrel. Nitro-carburizing changes the structure of the metal without building a layer in the bore increasing performance but, not decreasing accuracy."
I have multiple ARP barrels and they shoot better than I can. Just don't use Bullfrog, RUST_X or any rust preventer on nitrided barrels.
