Boss Barrels Carbon Fiber AR15 18″ 6.5 Grendel

Whether on the range or in the field this barrel can do it all. Built from a fully stress relieved, air gauged,
416R stainless blank turned down to a desired proile and reinforced with aerospace grade materials. Manufactured in-house using advanced composite technology, our composite reinforced barrels come in at a fraction of the weight of legacy steel barrel contours. By utilizing a multi-step process and proprietary thermally conductive material blends we are able to produce a much lighter barrel without sacrificing strength or rigidity.
