Stern Defense Rapid Attach Mini Buttstock Adapter Features The Stern Defense Rapid Attach Mini Buttstock Adapter lets shooters greatly reduce the length of their firearm for compact storage and easy transportation all without modifying the rifle itself. To detach the shooter simply pulls the bottom release tab and twists counter-clockwise 30 degrees separating the stock from the firearm in seconds. Reattaching is just as simple aligning the two pieces pushing in and turning clockwise 30 degrees until the steel locking mechanism automatically secures the connection. This quick detach capability is designed for firearms using AR style buffer tube stocks that do not require retention of a buffer weight and spring. Machined from 7075 aluminum and hard coat anodized for maximum wear protection the adapter is built to handle repeated attach and detach cycles without degrading. Three steel ball detents and a locking bolt provide a secure lock up that holds firm during normal handling and transport. Designed machined and assembled in the United States the adapter weighs just 2 ounces while adding only 1.25 inches to the length of pull.
