The Proof Research Sendero Carbon Fiber Barrel (brand part no. 104620) is a 22-inch bolt-action barrel chambered around .243-caliber cartridges, wrapped in carbon fiber to shed weight versus an equivalent steel barrel of the same length and contour. A 1-in-7.5 twist rate stabilizes the longer, high-BC .243 bullets favored for long-range and varmint work, and a 2.5-inch breech length with a 1.20-inch shank diameter are machined to standard bolt-action receiver specs. At roughly 3 pounds even, it stays substantially lighter than a comparable steel barrel, making it a strong choice for hunters and long-range shooters who want a flatter-shooting, lighter rifle in hand.
