Ball Mill Lightened Barrel
Knight’s Armament has pioneered a unique and highly
effective method for reducing weight and stress, while effectively dissipating heat
in our barrels. Several of our weapon systems feature a Ball Mill Lightened, or
Dimpled Barrel.
This process reduces the overall weight of the barrel and effectively increases the surface area, allowing it to cool faster than a standard or fluted barrel. The pattern of dimpling (rows of offset spheres) allows the stress inherently created by the process to be relieved by adjacent rows of dimpling. Any barrel with this sort of alteration has a natural yaw that will occur while firing; however, this dimpling pattern greatly reduces that undesired side effect. These barrels are extremely reliable, lightweight, quickly cooled, and accurate components.
