Guarder SP110 AEG Tune Up Spring

Guarder SP110 AEG Tune Up Spring – for your replica

This tune up spring determines the force with which your piston is propelled forward in the gearbox of your AEG. The SP110 from Guarder delivers approximately 340-390 FPS with 0.20g BBs, depending on your gearbox setup and air seal. You replace the main spring when you want to adjust the muzzle velocity for different field limits or when your current spring becomes fatigued after prolonged use. A strong AEG upgrade spring like this gives your replica more range and consistency.

Technical specifications

The SP110 spring is manufactured from hardened steel alloy with a black finish. This spring has a linear compression strength of 150% (M110 rating) and fits standard AEG gearboxes with regular spring guides. The coils are evenly spaced for consistent compression during each cycle.

Compatibility and application

This spring fits virtually all AEG gearbox versions (V2, V3, V6, V7) and is suitable for both standard and high-speed builds. Note that stronger springs like the SP110 put more stress on your gearbox components – check whether your gears, piston, and motor can handle the extra load. Installation requires gearbox disassembly experience.
