Ultradyne UD6 Combo Features The Ultradyne USA UD6 Combo chassis is machined from a solid bar of 6061 T6 aircraft aluminum a one-piece construction method that provides exceptional strength and durability compared to welded or multi-piece designs. Built specifically for the Ruger American Short Action the chassis replaces the factory stock with a modular platform that accepts AICS pattern magazines giving shooters access to widely available aftermarket magazine options. The 1.35 max barrel diameter accommodates a range of barrel contours from slim sporter profiles to heavier bull barrels favored by long-range shooters. Weighing between 1.1 and 1.5 pounds the chassis itself is remarkably light given the rigidity it provides. When paired with the included Ultradyne Adjustable Butt Stock the overall system remains lighter than most factory stocks while offering the ability to add up to 5 pounds of optional weights for shooters who prefer a heavier balance point. This flexibility makes the UD6 Combo suitable for hunting rifles weighing as little as 6 pounds all the way up to long-range target rifles weighing 16 pounds. The included FAB Defense Gradus Grip provides an ergonomic adjustable interface that improves hand positioning and trigger control. Finished in matte black and configured for right-handed shooters the Ultradyne USA UD6 Combo is offered for sale at GrabAGun for Ruger American Short Action owners looking to upgrade to a true precision rifle chassis.
