Star Rival Artemis 15KG Spring

The Star Rival Artemis 15KG Spring is currently doing double duty in the catalogue, marked down under SALE and sitting in the Bargain Bin at the same time, so if you've been eyeing an upgrade spring for your Nerf Rival Artemis, this is about as good a time to buy as it gets. It's a drop-in replacement rated at 15KG, giving the Artemis a clear step up in tension over its factory spring.

Since the Artemis is a springer blaster, every bit of its shot power comes from spring tension, so swapping in a stronger spring is one of the most direct upgrades available for the platform. It fits in exactly where the factory spring sits, no extra fitting or modification needed: pull the stock spring out and drop this one in. A solid pickup on its own, or alongside other Springer Internals parts if you're planning a bigger upgrade pass on your Artemis.
