Update 08/06/2025: Added a new version of the Muzzle (Hippo_8_Extended Muzzle). I extended the front of the muzzle so it gives more compression for the string and may give a performance boost. You can attach a longer Picatinny rail (Hippo_24_Picatinny for extended muzzle).
Hello hello Nerfers!
This is The Hippo, a new project I've been working on for the last 2 months and first time working on a Nerf Rival blaster.
This is a hopper fed string pistol that uses Rival (and X-shot chaos rounds) and holds up to 24 rounds in total. I recommend max 22 for better feeding. The performance is in the low to mid ranges of Rival, depending on the bungee string you use, but makes up for its high capacity. Because it's a string blaster and not an air Rival one, the behavior of the rounds is kind of unpredictable.
You also have the possibility to turn it into a single shot pistol or a Mega dart launcher, if you want for some reason (check assembly manual).
I strongly advice to read the instruction manual (linked in the files as a PDF) and check how to assemble, and especially how to fire this blaster. You have to get used to the priming and trigger pull. Anyways, all the stuff and details you need to know are in the manual.
One detail for printing: You need supports only for over hang of the hopper piece.
Before you print, you need some specific hardware parts:
And that’s pretty much it. I may add new parts in the future.
For now, hope you enjoy this blaster and happy Nerfing!!
