Spring M120 | Krytac

Spring M120 | Krytac – for your replica

This spring is the core of your AEG gearbox and determines the force with which the piston moves forward. The M120 spring from Krytac delivers an output of 394 FPS (measured with 0.20g BBs and a 300mm inner barrel). You replace a spring when you want to adjust the FPS of your replica for different field limits or when your current spring shows signs of fatigue. An airsoft spring upgrade is one of the most direct ways to influence the performance of your AEG.

Technical specifications

The spring has a length of 19 cm and is made of steel with a black finish. It is a linear spring from the Krytac Upgrade Series, designed to efficiently utilise motor torque. The coils are evenly distributed along the length, ensuring consistent compression during each cycle of your gearbox.

Compatibility and application

This spring fits standard V2 and V3 gearboxes commonly used in AEG replicas. Installation requires disassembly of your gearbox, so some technical experience is recommended. This M120 spring is suitable for outdoor skirmishes where higher FPS limits apply. Always check the local field rules before installing this spring.
