The Stern Defense RAB-AD features a quick-detach design: push the button and twist counter-clockwise 30 degrees to separate the buttstock from your firearm. Reattachment is equally straightforward—align the components, push in, and turn clockwise 30 degrees until the steel locking mechanism engages automatically. Built from 7075 aluminum construction with steel internals, the adapter delivers both durability and minimal weight. The RAB-AD is engineered to work across gas piston, direct impingement, direct blowback, and radial delayed blowback systems in the AR platform.
