Nerf Rival Saturn Lever Action Kit – by Shanye


This is the ultimate fun! This one goes out to all the Nerf cowboys who loved the Slingfire for its priming feeling but thought it was way to flimsy!
The lever action kit by Shanye for the Nerf Rival Saturn makes this blaster so much fun to use.

You can customize the look of your kit by choosing different filament colours below.
Silky filaments are not recommended as they are to brittle!

Please note, the carbon parts are always black/grey-ish. All version of this kit use flat carbon side bars and a carbon insert in the lever.

There are two different stock variants to choose from as well as an optional foregrip.
(The foregrip will be available shortly, we are finalizing the design)

Please choose the version you want:

Nerf Rival Saturn Lever Action kit

Take your Saturn to a whole new level! This kit transforms your Nerf Rival Saturn from a pump primed blaster to a lever primed blaster.
This is everything the Slingfire always wanted to be. XD

The kit includes custom machined carbon fiber parts for reinforcement inside the lever loop and as linkage arms. It also has two carbon tubes in the stock. All other parts are 3d printed.
You can choose the colours of your 3d printed parts as you wish however we do not recommend using silky filaments as they are to brittle. If you choose silk filaments you do so at your own risk.

This kit is build to be used with the stock spring. We have not tested it with any spring upgrades and recommend using the stock spring.


This kit comes with all hardware needed for the installation.
Please check the hardware picture for reference.

Tools required:
– Philips screwdriver
– Set of Allen keys for various screws
– Soldering iron or similar IF you choose to install the heat inserts yourself
– Maybe a small hammer or some plyers to help install the bolts

This kit does require to open the blaster nor to cut the shells. However you will need to remove the original grip. The lever is NOT compatible with the original grip.
The new one is way more comfy anyways ;).
