The Stern Defense Rapid Attach Mini Buttstock Adapter delivers a compact, tool-free way to quickly remove or install your AR-15 buttstock or pistol brace. Built from 7075 aluminum with steel internals and finished in black anodizing, this mini adapter trims bulk compared to standard units while maintaining a secure, repeatable lock-up on your rifle.

This adapter adds only a small amount of length and weight, making it ideal for shooters who need a firearm that stores and transports easily yet can be configured in seconds for range use or training. Designed to work with common AR-15 operating systems, it reflects Stern Defense’s focus on practical innovation and precise machining for modern rifle platforms.
