18KG Upgrade Spring Silver for NERF Rival Jupiter XIX-1000
The spring has been tested before they come out to the marketplace.
And we have designed different lengths and strengths so that to improve the shooting performance.
By the way of lengthening the spring, the Rival Jupiter XIX-1000 will have greater power.
There is no problem with the quality of our spring. But It does not determine that the buyer can install it successfully. Some NERF Rival Jupiter are very difficult to reassemble, and we won’t be able to troubleshoot problems caused by user errors.
If you encounter difficulties during installation, we have some installation instructions or videos for support to show how to complete the Rival Jupiter XIX-1000 upgrade.
