Take advantage of your CZ Scorpion EVO 3 A1's quick-change spring system with this M120 spring. The M120 will provide a muzzle velocity of 380 to 410 FPS, depending on your BB weight. Upgrade, downgrade, or just replace an old spring to suit your airsoft field and combat style.
Why choose this AEG spring?
Airsoft gun springs wear down over time and lose tension. If not properly maintained or replaced, they can cause a gun to lose as much 50 FPS of muzzle velocity.
