The Bergara Premier Series barreled action (brand part no. BPBA34-300WM) pairs a complete Bergara receiver with a factory-chambered .300 Winchester Magnum barrel, giving custom rifle builders a precision-grade foundation without starting from a bare action. This #6 contour barrel runs 24 inches long with a 1:10 twist rate tuned for heavier .300 Win Mag bullets, built on the same action Bergara uses across its complete rifles. It’s the right starting point for a builder assembling a long-range hunting or precision rig around a proven action and barrel combination rather than a full off-the-shelf rifle.
