The Ultradyne UD3 chassis is a precision one-piece aluminum build platform designed for shooters who want a modular, durable foundation for hunting rifles, precision target builds, or anything in between. Machined from 6061 T6 aircraft aluminum, this chassis delivers the strength of a solid bar stock design while keeping weight between 1.1 and 1.5 pounds—light enough to complement rifles as lean as 6 pounds, yet stable enough to support heavy long-range setups up to 16 pounds. Whether you're running a lightweight hunting rifle or a dedicated precision rig, the UD3 adapts to your needs without dragging down your total weight budget.
The right-hand configuration pairs a FAB Defense Gradus grip (a proven ergonomic choice for both prone and standing positions) with an AICS magazine interface, giving you access to decades of aftermarket support and compatibility. The 1.35-inch maximum barrel diameter accommodation handles most modern rifle profiles without hassle. Three accessory slots built into the chassis rails give you flexibility to add your choice of tactical furniture—rails, MLok systems, or other modular additions—as your setup evolves.
Pair this chassis with an Ultradyne adjustable butt stock to dial in length of pull and cheek weld for your body and shooting style. Even fully configured, you'll still come in lighter than most factory stocks, and the modular approach means you can add weight where it matters most for your application—whether that's stability or speed. If you're building a precision rifle, a hunting platform, or experimenting with a new caliber, the UD3 gives you a clean, repeatable foundation that won't nickel-and-dime you with unnecessary bulk.
