Stern Defense RAB-AD Pic Rail Rapid Attach Buttstock Adapter - Black Aluminum/Steel

The Stern Defense RAB-AD Pic Rail Rapid Attach Buttstock Adapter is a compact, no-modification-required mounting solution that lets you attach or remove a buttstock or pistol brace to a Picatinny rail in seconds. Engineered around a 7075-T6 aluminum body paired with hardened steel internal components, it locks up through three steel ball detents and a center locking bolt for a secure, repeatable fit every time. An integrated buffer retainer streamlines reassembly, and the hard coat anodized finish protects against wear in the field. At just 2 ounces, the adapter keeps your build light without sacrificing strength. Designed, machined, and assembled in the USA, the RAB-AD Pic Rail is built for AR-style buffer tube stocks and ready for duty use.
