Chrome lined is much more durable, and doesn't require break-in. Chrome-moly is more accurate. Rock River sells mostly chrome-moly barrels, and they guarentee specific accuracy.

Check out "so you want to buy an ar-15". It has a real nice write-up on the difference.

Or you could get a good stainless steel barrel. They're a good middle of the road compromise for both types. Really decent life and usually better accuracy than a run of the mill lined barrel.

look for one that's chambered for either 5.56 or a wylde chamber if you want to use both .223 and 5.56 nato rounds. If the best accuracy is what you're looking for go with a match .223 chamber, though you'll only be able to shoot commercial .223 rounds and mil-surp will be out of the question.

The faster the twist (1:7) will be better suited for the heaviest rounds while a 1:9 will do just fine up to around the mid 60 gr ammo's and is the most common twist rate today.

chrome moly is a type of steel used, and chrome lined in a treatment after the barrell is manufactured.
