    More AR questions

    I think I've finally broken down and am going to order my AR from RRA.
    I have a question on rifle barrels what is the difference/advantage of Chrome/moly vs Chrome lined vs stainless steel?

    Thanks

    Not much difference. Chrome lined bore allegedly lasts longer but is less accurate. If you clean your rifle after every use it will not matter. FWIW, neither of my AR's are chrome lined. I really don't think it makes any difference. I am sure there are some who will disagree but as a civilian sport shooter I really dont get to send thousands of rounds downrange over the course of a year for it to make a difference. And the ammo I do use is non-corrosive anyway.

    Chrome-lined bores last significantly longer, as well as easier to clean. The less you shoot the less a benefit this is to you, really.

    +1 to both.

    Accuracy go stainless or chrome-moly.

    Longevity go chrome lined.

    If you are looking for a match rifle, go stainless.

    If you are looking for an all around rifle, go with chrome lined. It's easier to clean, and lasts longer. As far as accuracy concerns, the military rifles are all chrome lined, and I can hit in the black at 500 yards no problem on a human size silhouette.

    Chrome line rifles began life because full auto fire is hard on them. When they got very hot from continuous fire, they tend to erode in the throat area much quicker than normal.

    Since AR's are semi, there isn't much advantage to it other than not having to clean them so often.

    I have had several of both and unless you are shooting for competition where scores are measured in thousanths of inches, there isnt enough difference for the average shooter to worry about.
