Ready to show some new-found PDA to your German PDW? JMac Customs has your back. The West Virginia based Kalash builder has just introduced the RSA-MP5K stock attachment for the MP5K and suitable clones that allows owners to drop in a Sig Sauer MPX/MCX folding stock and show their rollerlocks the affection they deserve. Stocks can be adjusted vertically for a better check weld or to match the shooter’s style.

Alternatively, the new backplate can serve as a home for a number of different pistol stabilizing braces. As a reminder, even with a PSB, a vertical foregrip makes an MP5K an NFA require a form, file, $200 and a wait.

Details, information and links can be found below.
