The Stern Defense 008SDRABADD1M Rapid Attach Buttstock Adapter Black Aluminum/Steel is engineered to let you remove and reinstall your AR buttstock in seconds without changing your existing buffer system. Machined from 7075 aluminum with steel internals and a hard coat anodized finish, the RAB-AD adds only 3.5 ounces and about 1.25 inches to length of pull while delivering a secure, repeatable lockup.

To detach, simply press the side button and rotate the adapter counter-clockwise 30 degrees; the buttstock slides free for compact storage or discreet transport. Re-attachment is just as straightforward—align the halves, push together, and twist clockwise 30 degrees until the steel locking mechanism cams into place. Designed for AR-15 platforms using gas piston, direct impingement, direct blowback, or radial delayed blowback systems, the RAB-AD includes a buffer retainer and spacer compatible with standard-length AR-15 bolts, reflecting Stern Defense’s focus on practical innovation and precise machining.
