The HK roller delayed series of firearms all suffer from stocks which are too long for most end users. This is especially apparent when it comes to shorter shooters and the use of body armor. To improve the ergonomics of the rifle Spuhr have made a stock adaptor in order so it may accept M4 type stocks.

The stock adapter allowa stocks to be adjustable in length from 50 mm (2”) shorter to about 40 mm (1,6”) longer than standard and also raise the cheek piece and butt plate around 20 mm (0,8”).

This allows the length of pull to be adjusted to the current clothing or the current user of the firearm. It also makes the gun more controllable as the stock is more optimized after the user and also because of the raised butt plate placing recoil in a direct line.

Total stock weight of 495 grams is a reduction of nearly 30% against the original retractable stock of 700 grams. The left and right QD sling interfaces facilitate easy use of either a single point or a dual point sling.

The stock adapter is optimized for medium height optical sights such as SM-2001, SM-2007 making the original open sights redundant.


  • Precision machined from aluminium
  • Dual integral QD sling points
  • Type III hardcoat anodized
