It seems we are missing a little common sense in this discussion. One of the great things about the AR is it's ability to be easily adapted to vary different rolls. To tell someone to "go chrome or go home" is just as silly as telling someone that you can't hit shit with a chrome lined barrel. Both are gross over simplifications. Why compromise the versatility of the AR by limiting yourself to one kind of barrel or another. I shoot HP competition with my AR, and also do a little prairie dog shooting. For me, I'll take the added accuracy of a good quality SS barrel. I have never had any reliability issues with them and I have been known to skip cleaning my rifle a few times after a long day of shooting. However, this does not mean that I think a SS barrel is for everyone. If I were to build a truck gun, something that I could throw in the back of the truck, drag through every kind of shit, use for a jack handle if needed, never clean, and know that it was going to be there and ready when needed, it would have a chrome barrel. If I were to build a rifle to take to war in a jungle, you can bet it would have a chrome lined barrel. Just maybe, before we tell someone what kind of barrel he should get, we should ask him what his intended use is for the rifle. This just might let us give him a much more informed answer and increase his odds of being a happy AR owner or customer. And we do want everyone to be happy don't we? :-)
