No problem. There's a thread or two somewhere around here about the carbon barrels: in short, it's a pencil steel barrel under a detached carbon sleeve that's held in place using a nut of some sort (I haven't looked at the details). All carbon barrels are thinner steel cores with a carbon exterior; however, the quality ones have the carbon layered directly onto the steel core, and are in direct contact with the steel. This allows for decent heat transfer from the core into the carbon.
Bergara's factory carbon barrel, on the other hand, has a detached carbon sleeve around the steel core, which a) lends very little rigidity if any at all to the overall barrel, and b) will actually insulate the barrel core and leave it hotter for longer. Now, heat isn't a huge issue with 22LR, but still, the rigidity concern alone is enough for most of us to steer clear.
