Gunsmiths are always looking for sources for quality barrels. There are several good makers in the United States. Douglas, Hart, Krieger and Pac-Nor to name a few. Bergara is a Spanish barrel maker. They recently purchased new equipment that have allowed them to expand operations both in Spain and the U.S.
Shooters of the T.C. Encore™ have probably heard of Bergara Barrels, because they manufacture replacement barrels for the famous Encore™ pistols and rifles. Accuracy reports from these barrels have been very good. Of late Bergara USA is offering much more, including tapered barrel blanks for gunsmiths.
Prices are comparable to other barrels in the marketplace.
The video below is an introduction to the manufacturing processes used by Bergara to make barrels. Pretty interesting if you have never seen a barrel made. Bergara has invested in some new high-tech gun drills and equipment to manufacture quality barrels in a less labor intensive process.
