This is a Proof Research carbon fiber wrapped barrel blank in .308 caliber, 24 inches, in a Sendero contour, supplied unchambered for a gunsmith to fit. Proof pioneered the carbon-wrapped barrel, and the engineering argument is straightforward: carbon fiber is stiffer per unit of weight than steel and dissipates heat more effectively, so a carbon-wrapped barrel of a given weight resists both vibration and the heat-driven point-of-impact shift that thin steel profiles suffer. The Sendero contour gives a heavy, stable platform for a precision or long-range hunting build. Professional installation required.
