Out Of Darts Upgrade Spring for Rival Kronos

5,50

This upgrade spring for the Kronos is a custom made spring designed by Out Of Darts. You can expect about 135-140 FPS performance after installing. It makes the prime heavy, so not suited for kids. A T-pull handle will make the prime a lot easier.
