KES HK MP5K Buttstock

The all new KES for the MP5k. Specially designed to fit HK clones with two pins affixing the rear receiver cap.


  • Guide rods slide into the existing slots present on the receiver
  • Rods machined to go underneath the reinforcing piece welded onto the rear of the receiver
  • Multi position (3 + closed) rapid pull rods. One button press and a constant rearward motion will fully retract the KES
  • 12.5" Length of pull
  • Extends 9.250" from the rear of the receiver.
  • Guide rods are 01 steel drill rod, black oxide
  • Button is 1018 steel, nitrided
  • Main body and tailhook adapter/buttstock are 6061 aluminum, type III hardcoat anodized

Note: This is only for the K models with the 2 pins in back.  Will NOT fit the full size or reverse stretch guns

Due to the stamped/bent receivers on HK pattern guns and the number of manufactures producing clones fitment may vary. If fitment is unsatisfactory returns and subsequent refunds will be accepted/processed. Product will need to be unmodified to qualify for refund of the purchase price.

    Went on a AP5-P SBR. I wanted the smallest package, shooting exclusively suppressed, leaving the suppressor on for HD purpose. The stock was easy to install, with one of the pins needing a little tapping. Solid and beautifully designed stock, adding

    Looks like if my K was not a 10mm the KES would slide snuggly in. But the extra crease needed on the 40cal and 10mm for the bolt hole open on the receiver get in the way. A slight mod to the collapsible stock will take care of it, but you think these guys would have taken that in consideration with how well this thing's built. That little area could have been easily shaved down. With that said, there is just enough room where when collapsed it doesn't press into your wrist. Nice design guys.

    After getting my SBR tax stamp, this stock is 100% the way to go. It’s the only one for the K that uses the factory stock grooves. Easy install (on the HK models at least), easier deployment and this is one solid stock! This one’s a winner. So glad HKP is carrying this!

    Stocks are awesome fits my century/MKE SBR awesome love the all metal construction. Cheek weld is not super comfortable but is as expected on the rods but there is some real estate at the front end of the stock that you can put your cheek into nicely
