Other than being a "Made in Spain" barrel, I've never heard of Bergara.

I would offer that CVA is simply "Marketing" their barrel and arm manufacturer by Brand "Beraga" to offer additional credibility for sales purposes.

I don't think that Beraga and Thompson/Center are in the same galaxy quality-wise.
