Christensen Arms barrels

[GetReel]

Has anyone used a Christensen Ams barrel on a .308 AR-10 build?
I bought a receiver to build a .308 and my goal is a lightweight AR that will also holt a respectable group out to 500. I was thinking between an 18" or 20" barrel length.

I have not used one but also haven't heard much a ad about them. That could be seen as a good thing.
