Compatible Replicas

  • CZ Scorpion EVO 3 - A1 (primary compatibility)
  • Most standard AEGs (Gearbox Version 2 and compatible models)

AEG Installation and Internal Upgrade

Replacing the spring is one of the most common procedures for adjusting or restoring an AEG’s FPS output. The M120 spring is part of a maintenance or internal upgrade process: it can replace a worn-out spring or be installed to achieve a target power of 400 FPS, a common limit at many regulated playing fields in France.

Expert Opinion

"On the Scorpion EVO, generic springs often cause issues with gearbox side play or premature piston wear. Opting for the official ASG part number 18179 helps you avoid these kinds of headaches: the dimensions are precise, the compression is consistent, and the 400 FPS power holds up over time. It’s a minimal investment for real-world reliability on the field.”
