Official ASG M120 replacement spring (Part No. 18179) designed specifically for the CZ Scorpion EVO 3 - A1, compatible with most standard AEGs.
Produces approximately 400 FPS with a 0.20 g BB; made of metal for optimal resistance to repeated compression cycles.
The M120 ASG spring, part number 18179, is a genuine replacement part designed for the CZ Scorpion EVO 3 - A1. Made of solid metal, it is sized to the manufacturer’s specifications for installation in the replica’s gearbox without modification. Its construction ensures consistent and repeatable compression throughout all firing cycles.
This spring is primarily designed for the CZ Scorpion EVO 3 - A1. Its standard geometry also makes it interchangeable with most standard AEGs on the market. It is therefore a versatile investment for any technician who maintains multiple replicas.
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.
"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.”
