The Stern Defense Rapid Attach Buttstock Adapter (brand part number 008-SD RAB-AD-D1-M) lets AR-platform shooters swap buttstocks without tools, using a quarter-turn quick-detach interface. Push the button and twist 30 degrees counter-clockwise to separate the stock from the receiver extension; align, push in, and twist 30 degrees clockwise to lock it back on, with a steel locking mechanism that automatically secures the connection. Built from 7075 aluminum with steel internals, it’s both lightweight and robust, and it works across gas piston, direct impingement, direct blowback, and radial delayed blowback AR-platform systems.
