The Ballistic Advantage 13.7-inch 5.56 NATO Hanson Barrel (brand part no. BABL556028F) is part of Ballistic Advantage’s Performance Series, built to the same standard the brand applies across every length and profile it produces: tight accuracy, precise contouring, and consistent function. This barrel uses Ballistic Advantage’s proprietary Hanson profile and ships with a pinned low-profile gas block already installed, saving a separate purchase and a trip to the gunsmith for that step.
