Manufactured as a Polymer/Aluminum hybrid, our rear adapter provides the OE fit of the polymer adapter with a heavy duty 1/4in thick aluminum insert that supports the recoil spring seat and reinforces the stock mount. Completely unique in design, this adapter provides improved stability by covering more surface area of the receiver. We also include a 1/2in thick high-density polyurethane buffer. The A3 Industries adapter allows the use of our complete line of modular stocks and braces and can also be configured with our Picatinny rail. The Picatinny rail will allow you to adapt any side folding stock (or arm brace) designed for use with Picatinny style mounts.

The bolt pattern and locating lug on the rear of the adapter provides a positive modular mounting platform for a wide variety of currently available stocks/braces.
