Wolverine Quake HPA Recoil Stock for M4 (Stock / Spartan Board)

HPA Systems and Accessories

Designed to work with any Wolverine Airsoft HPA engine, the QUAKE stock adds an extra level of realism which was not available with any Electropneumatic HPA system until now!



Technical Notes:

  • The QUAKE stock does require permanent modification of the gun, and we will provide a detailed video tutorial on installation.
  • Wolverine Airsoft is not responsible for parts falling off, breaking, etc. from the recoil which most AEG's are not designed to for.
  • We recommend using the recoil stock in the 100-140 PSI for maximum recoil feel. In order to accomplish this, we recommend short barrel builds.
  • We will offer a flow reducing option in the future for the engine to reduce the output energy and allow higher operating pressure for longer barrel builds.


  • Programmable ROF
  • Custom Spartan Board for simple programming (option 2)
  • Compatible with most metal body M4's
  • The low-pressure line included (Allow higher operation pressure for better recoil feedback while maintaining standard power)
