Marq "Turbo" Spring

For the Original (Non Proficiency) Engine. Features:

  • Greatly reduced spring tension allows for lowered pressures and Dwell
  • Typical settings after installation: Dwell 6, LPR 60
  • Reduced ram pressures greatly mitigate recoil and vibration while decreasing sound signature
  • Lower LPR pressures contribute to less ball breakage in the breech and ball stack
  • Efficiency unaffected by smoother shot


A replacement Poppet spring for stock Marq engines, this upgrade provides just enough tension to do the job of resetting the poppet efficiently, while requiring greatly reduced force from the ram assembly.

Price: $7
