I have 2 of my own and have now worked with a half-dozen other Bergara Encore barrels. All have been sub-MOA right out of the package. The crowns look good and concentric, the chambers are in alignment with the axis of the bore, and there are actually leades in these barrels -- something you will never find in a factory TC tube.
And while the finishes are nice, this is one area that does fall a little short of a TC factory barrel. All things considered, though, that's a rather minor complaint in my books.
As to Bergara being a little slow in getting the barrels out to the public, I'd have to say they have done a much better job than the likes of Remington and a few others. Heck, I had a Remington product on order for over 2 years, and it never went into production -- that despite heavy advertising for a number of months. And while I love my Nikon scopes, the new Monarch lineup saw a number of new "release" dates before they finally hit the shelves (and they still aren't out there in good numbers).
