These 6.5 Creedmoor chambered (DPMS style) barrels are machined from 416R Stainless Steel with a bead blasted finish. Premium Series 6.5 Creedmoor Barrels are proof fired and MPI tested, ensuring the best in quality and accuracy. 6.5 Creedmoor is the perfect option if you're looking to maximize the accuracy of your .308 platform. Apart from a simple barrel swap, all parts, including the bolt and mag, remain the same as a normal .308 build. The inherently accurate 6.5mm projectile, the increasing amount of off-the-shelf match grade factory 6.5 Creedmoor ammunition, and the extremely soft recoil pulse all combine to create one of the best black rifle options available.
