I think you need to ask your self this question first . How many rounds do you think you will put down range in the life of the gun . This year alone I've shot 1,500+ rounds of 223/5.56 through 3 ARs . At the rate of 500 rounds a year any barrel will last many years . If you plan on only having 1 AR and shoot as much as I do . I would get a chrome lined barrel . When ever I buy a gun , I plan on keeping it for the life of me then handing it down to my son . I know it's stupid but I don't want him saying , hey I got all my dads guns but there all garbage cus he shot them into the ground . A chrome lined barrel should be good for 25,000+ rounds .A untreated chrome alloy vanadium barrel will shoot 10,000+ rounds . The melonite coated barrels expected life I do not know.
I would consider how many rounds you plan to put through the gun in it's/your life as well as what you plan to use it for .
If you plan on the gun being your HD/plinking gun and you plan to shoot the heck out of it . I recommend a lined/coated bore . If you plan to shoot competition and for accuracy you would not want it chrome lined and most likely stainless chambered in 223 wylde .
Hope this helps , if not never mind

Anyone else find it sad that those who preach tolerance CAN'T allow the existence, occurrence, or practice of something that they do not necessarily like or agree with , without interference
