VTAC Barrels any good?

[The Fuzz]

I'm going to have a AR put together by Ray Saltzman soon and I'm looking for good quality parts. I have everything else down but the barrel. I want a light weight barrel and see that Kyle Lamb is selling barrels on his site. They are made by Christensen Arms of which I have no experience with. Does anyone have any info on them for me?

What kind of rifle? If more combat/le/training course oriented, I'd go with daniel defense. They make a LW CHF barrel with pinned gas block.
