Rival Knockout Spring

This precut Rival Knockout from the K25 spring is the perfect upgrade mod for your blaster for more incredible speed and accuracy. This mod is not for young kids, as you’ll need to compress the spring a bit when installing it in the plunger tube! You can lose the plastic pieces in the handle, but everything else should stay where it is; you only need to remove the plunger tube. Use a flathead screwdriver to remove the cover off the notches, and be careful as it sits on a pretty tight fit. This spring, it has been custom-cut and tested to fit the Rival Knockout blaster.
