Stern Defense Rapid Attach Buttstock Adapter Features The Stern Defense Rapid Attach Buttstock Adapter is machined from 7075 aluminum and paired with steel internals giving it the strength to handle repeated detach and reattach cycles without wearing loose. To detach the stock the shooter pushes the button and twists counter-clockwise 30 degrees separating the buttstock from the firearm in one motion. Reattaching is just as fast aligning the two halves pushing in and turning clockwise 30 degrees until the steel locking mechanism automatically secures the connection. The hard coat anodized finish protects the adapter from wear during the frequent handling this kind of quick-detach hardware sees. A built-in buffer retainer keeps the buffer weight seated inside the buffer tube even while the stock is fully detached preventing parts from falling out during storage or transport. The adapter includes a buffer spacer compatible with all standard-length AR-15 bolts and is compatible with the JP silent capture spring for shooters running that system. At roughly 3.5 ounces the RAB-AD adds minimal weight while shrinking the rifle s footprint considerably for compact cases or vehicle storage. Designed machined and assembled in the USA this adapter is available for sale at GrabAGun for AR-15 owners who need fast tool-free stock removal.
