First, each barrel is straightened, and then a deep hole drilling
machine cuts the barrel channel to the proper diameter. Barrels are then
honed using three diamond-tipped spindles. This process eliminates the need
for hand-lapping, ensuring a smooth interior surface free of machining marks.
Barrels are then button rifled, a process that allows Bergara to keep
tolerances less than .0002 inches, ensuring the straightest, truest barrels
available on these custom rifles. The final step in the process involves the
use of a high temperature heating process that realigns the molecules in the
steel and relieves stress, creating a perfectly smooth bore.
