Ultradyne UD6 Combo Chassis Features The Ultradyne USA UD6 Combo chassis is machined from a solid bar of 6061 T6 aircraft aluminum giving it the strength and rigidity needed for consistent accuracy without adding unnecessary bulk. The one-piece design keeps weight between 1.1 and 1.5 pounds depending on configuration making it suitable for hunting rifles as light as 6 pounds and long range target builds up to 16 pounds. An AICS magazine interface lets shooters run widely available detachable box magazines while a 1.35 inch max barrel diameter accommodates heavier target contour barrels. The 6 slot M-LOK handguard provides mounting points for bipods lights and other accessories without adding significant weight. Paired with Ultradyne s adjustable butt stock the UD6 Combo is lighter than most factory stocks yet can add up to 5 pounds with optional weights for shooters who prefer a heavier rear balance for prone or bench shooting. The included FAB Defense Gradus grip gives shooters an ergonomic vertical hand position that improves control during recoil management. Finished in matte black and built specifically for Remington 700 short action receivers this chassis is a direct drop-in upgrade for shooters looking to modernize a proven action. The Ultradyne USA UD6 Combo is a complete solution for turning a Remington 700 short action into an adjustable precision-ready rifle.
