This pack contains 3 (three) springs. Each spring has a power output of over 5 kilograms (2.5kg stock).
Disclaimer: Mod at your own risk! Increasing the spring tension can break or damage the stock internal components of your blaster. By purchasing, you agree not to hold Orange Mod Works liable should this occur. In addition, some blasters are extremely hard to reassemble, and we won't be able to troubleshoot problems due to user error.
