Ultradyne UD3 Picatinny Combo Ruger American Rifle Chassis UD20174-AB w/ Free S&H

The UD Picatinny Chassis refines the proven platform of the UD Chassis into a more practical, more adaptable option for the modern rifle

owner. We replaced the traditional buffer-tube interface with a robust, rear Picatinny mounting point so your butt stock detaches

quickly for compact transport or tight storage without compromising repeatable return-to-zero.

Ergonomics were a primary focus in our design. The chassis accepts an adjustable grip so shooters can customize trigger-finger distance to their preference, and the adjustable thumb rest lets you tune positioning for repeatability and comfort. Functionally, the Picatinny Chassis keeps compatibility with mil-spec AR grips, accepts detachable AICS magazines, and retains the integrated ARCA rail along the forend with M-LOK slots for accessories. A forward spigot location gives optional ARCA length extension, and a NV bridge mount provides a clip-on thermal/optic interface. The result: a chassis thats transportable, configurable, and purpose-built for precision.
