1913 PICATINNY ADAPTER - HK MP5 .22LR

Fits: HK MP5 22LR ONLY - Not for use with traditional 9mm MP5/SP5 and clones

Manufactured as a Polymer/Aluminum hybrid, our rear adapter provides the OE fit of the polymer adapter with a heavy duty 1/4" thick aluminum insert to reinforce the mount for the stock or brace. Completely unique in design, this adapter provides improved stability by covering more surface area of the receiver. The A3 Tactical adapter allows the use of our complete line of modular stocks and braces and is configured with an aluminum 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.
