The Pepperbox Knockout kit by Ehdrien

The Pepperbox Knockout kit by Ehdrien turns your Nerf Rival Knockout into a short dart shotgun pistol blaster. It is so much fun to shoot and will fire four short darts at once!

The perfect backup blaster in any scenario.

The Pepperbox is part of the Ehdriens Knockout Trilogy, so if you want more Knockout mods, check out the Mega KO and the Mayday Mk1!

The smooth trigger and the T-Pull are optional and can also be purchased separately.


– this kit will come with the additional hardware needed for installation

Tools required:
– Philips screwdriver
– Set of Allen keys
– Plyers & hobby knife to remove the Rival-AR-thingy


This kit requires no external shell cutting to install however you will need to remove the Rival-AR-thingy.
Everything else is pretty straight forward.
I build the entire trilogy in a live stream so check it for some installation help.
