Stern Defense RAB-AD Mini Rapid Attach Buttstock Adapter

The Stern Defense RAB-AD Mini Rapid Attach Buttstock Adapter provides a compact, quick-detach interface for AR-platform firearms. It features 7075 aluminum construction with steel internals for a balance of strength and reduced weight. The adapter is designed for use with gas piston, direct impingement, direct blow back and radial delayed blowback systems. An anodized black finish offers surface wear resistance during routine use.

To detach, push the button and twist counter-clockwise 30 degrees. The buttstock will then be separated from the firearm. To re-attach, align the two pieces, push in and turn clockwise 30 degrees. The steel locking mechanism automatically secures the adapter.
