Christensen Arms Barrel Blank Features The Christensen Arms Barrel Blank is built using the company s proprietary carbon fiber layering process wrapping a match-grade 416R stainless steel liner in a carbon fiber shell that dramatically reduces weight compared to a traditional steel barrel of the same target contour. The stainless liner is measured to a tolerance of plus or minus 0.0001 inch then bored reamed hand lapped and button rifled with a 1:10 twist rate to deliver the accuracy precision rifle builders demand from a .308 caliber barrel. At 24 inches with a target contour the blank is suited to long-range precision applications where a heavier steel barrel would add unwanted weight to the finished rifle. The barrel ships with a threaded muzzle and thread protector already installed saving the gunsmith an extra step during the build process. Because this is an unchambered blank rather than a finished ready-to-install barrel chamber finishing should only be performed by a qualified gunsmith to ensure proper headspace and function on the intended Remington 700 pattern action. The reduced weight of the carbon fiber construction makes it an excellent option for hunters and long-range shooters who want to keep their finished rifle lighter without giving up the accuracy of a heavier steel barrel since every ounce saved forward of the action improves handling and reduces fatigue on long days in the field or behind a long-range rifle. Estimated blank weight in .308 caliber depending on final length runs between roughly 2 pounds 12 ounces and 3 pounds 5 ounces before chambering and fitting giving a builder a reliable planning figure when balancing a finished rifle s overall weight. For custom rifle builders working with a Remington 700 pattern action this Christensen Arms carbon fiber blank offers a proven path to a lighter more accurate finished barrel backed by the same proprietary layering process the company uses across its factory rifle lineup.
