Ultradyne UD3 Picatinny Savage Rifle Chassis Short Action Right Hand Midnight Bronze. 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.
