Unicorn Airsoft UNIspring AEG Non-Linear Spring For AEG – M110

The UNIspring series by UNICORN Airsoft is designed to fit and work with a wide variety of standard AEGs. The UNIspring series of AEG springs feature a non-linear design with irregular pitches which reduces wear and stress points inside the gearbox of your AEG Airsoft gun and enhances the performance and reliability of your Airsoft electric gun. Made using high-quality spring steel, it is very durable and will allow your AEG build to perform optimally. It is a simple drop-in installation and does not require modifications to fit.

Please note that the "M" spring rates are based on the rough meters per second using 0.2g BBs. You can expect roughly 100 M/S (328 FPS) +/- 5 M/S on an M100 spring. The M/S or FPS can vary considerably due to the entire build set-up. Please keep in mind to do research when choosing a spring.
