Ultradyne UD6 Picatinny Chassis for Ruger American Short Action Armor Black

From MidwayUSA

All the performance of the UD Chassis, now with a Picatinny rear mount for instant-detach stocks and next-level ergonomics. The UD Picatinny Chassis refines the proven platform of the UD Chassis into a more practical, more adaptable option for the modern rifle owner. Ultradyne replaced the traditional buffer-tube interface with a robust, rear Picatinny mounting point so your buttstock detaches quickly for compact transport or tight storage without compromising repeatable return-to-zero.Ergonomics were a primary focus in our design.
