1913 PICATINNY ADAPTER - HK MP5-K/SP5-K DOUBLE PIN

Machined from 6061 T6 aluminum and hard anodized, this rear stock/brace adapter replaces the original end plate on your MP5K and clones. Our adapter allows the use of our modular line of stocks and braces and can also be configured with our Picatinny rail to adapt any side folding stock (or arm brace) designed for clamping onto a rear Picatinny rail.

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 and braces.
