It sure is, as a matter of fact, i wouldn't buy a non chrome linned barrel for any of my ARs.

HUNTER.

Two guns, both just out of the box, one with a chrome lined barrel, the other without... No one will see an accuracy difference. If you build the gun up, add a match trigger, free float the barrel, get match sights or a magnified scope, shoot match grade ammo, *then*, MAYBE, you will see a SMALL difference in accuracy. Maybe.

A standard shooter should have chrome lining. If your building a task specific gun with specail accuracy requirements, maybe consider a match, non-chrome barrel. Otherwise, get the chrome.

Quoted: chromed lined is a MUST for ARs

No, it isnt. It is possibly a must for some AR's, but there are many different types of ARs.

Quoted: Read Sept 2005 SWAT magazine (p48) and you might realize the main drawback of chrome barrels.  The accuracy potential is poor, and the protective element of chrome does not last as long as one might hope.  Good article.

Admit up front that I have not read the article, but did you read what I posted about this in the first page of the post? Two guns, stock out of the box, one with a chrome lined barrel, the other with chrome-moly. you are not going to notice a bit of difference in accuracy. Even if the potential is greater with the non chrome lined, things like a standard (i.e. heavy) trigger, iron sights, limitations in the accuracy of standard ammo, etc, will all do more to keep you from the true accuracy potential of your gun than chrome lining will. If you dont believe that, please explain.

In addition, chrome lining may not be able to deliver extreme accuracy, but define what you are looking for? For a standard gun (which is what the guy in this thread is looking for), a chrome lined barrel that is made by a company who gives a crap, will perform quite well. In fact, probably better than most would expect. I have and have seen my fair share of chrome lined barrel that are capable of shooting sub-moa out to 300, and one of mine (the only one I have tried I might add) will shoot under 2 moa at 600. FN sniper rifles are, in fact, made with chrome lined barrels. So, what Im asking is, if accuracy potential in chrome lined barrels is so poor, what is your accuracy expectation? 1/3 moa, 1/4 moa? What?

Chrome lining helps in a barrel being used on a all purpose gun. Whatever (if anything appreciable) it gives up in accuracy, it makes up for in barrel life, corrosion resistance, possibly even slicker surface of the chamber for feeding and extraction, and ease of maintenence among some other reasons neither of us may even be aware of. And I say this as someone who owns just as many guns with chrome lining as without.
