Stern Defense Rapid Attach Mini Buttstock Adapter - Black Aluminum/Steel

The Stern Defense Rapid Attach Mini Buttstock Adapter lets you mount and release your AR-15 buttstock or pistol brace in seconds without tools. Built around a steel locking mechanism housed in a body of 7075 aluminum with steel internals, this compact adapter is anodized black for a durable, low-glare finish that matches most rifle builds.

The Mini trims the bulk of a standard adapter so it adds only about 1.25 inches to your length of pull and roughly 3.5 ounces of carry weight, keeping your firearm compact for transport and storage. The tool-free design automatically locks and releases the stock or brace in seconds for fast transitions, ideal for shooters who want quick detachment of a buttstock or pistol stabilizing brace without giving up a secure, repeatable lock-up.
