Premium Bartlein stainless barrel chambered in .280 Ackley Improved by Sean Davison of Davison Precision Rifles. This barrel was built for a Borden Timberline (Remington 700 footprint) action and features a 1:8.7 twist, 3B contour, approximately 24-inch length, and a seamless shoulder-timed Davison Precision Rifles muzzle brake. Approximately 423 rounds have been fired through the barrel. It was removed only because I switched to a lighter hunting barrel, not because of accuracy or wear. Excellent condition and ready for your next build.
