Star Rival Hades 15KG Spring

Built for the Nerf Rival Hades, the Star Rival Hades 15KG Spring is a drop-in replacement spring rated at 15KG, giving you more tension than the factory spring without changing anything else about how the blaster goes together. Since the Hades is a springer blaster, all of its shot power comes from that spring, so this is one of the simplest and most direct upgrades you can make to the platform.

It installs the same way the stock spring comes out, no extra machining or fitting required, which makes it a good pick even if this is your first time opening up internals on a Hades. Currently sitting in the Bargain Bin, it's an affordable way to get a real power bump out of your Hades rather than spending on a full internals rebuild. Pick one up alongside other Springer Internals parts if you're planning a fuller upgrade pass on the blaster.
