Additional Information:Every barrel is precision chambered to SAMMI specifications and fully threaded in either a blued or matte stainless steel finish. This system makes Bergara Barrels the fastest installation on the market for Savage rifles. All that is required for conversion is a vice, a strap wrench and a set of chamber gauges. Note: Selected caliber must match existing bolt face diameter. Barrel diameters follow factory contours as close as possible but some minor stock inletting may be required.
