NERF RAMPAGE PRO X (Half length Conversion Kit 3D Parts) Updated for Smoother Chambering!!!

This is my take on how to make a NERF RAMPAGE PRO X (Half length) Pro LvL PRIMARY w/ an Average FPS of 125-130 with a 9kg Spring & Integrated Worker PCAR

& requires NO SHELL CUTTING!!!!!

Took the concept of Alternative_Cap_277 (Nerfreddit) Rampage X concept and made my own Conversion kit turning the Rampage into a PRO LvL PRIMARY for Half Length (Straight Talon Mags)

My Conversion Kit contains multiple 3D printed parts that can be used with other standard Worker Mod products to achieve a Pro lvl Build 

I have attached the build guide which explains all of the 3D parts needed and how to install. 

Listed in the guide are the other required purchased parts needed to complete the kit (most mod'ers may already have some of this stuff lying around).

• (estimated cost $30 +Barrel from Worker Mods or $25 +Barrel from Out of Darts)

After Initial testing my reinforced Sled is handling the 9kg spring well. I did not slamfire it 100 times in a row to stress test it neither. But under normal priming and plinking the sled shows no wear or tear!

UPDATE 4/20/2025: Dart alignment correction. 

I have replaced the original pusher with a skinny version. This version is required with the mag spacer to correct the chambering alignment.

This will require “shell cutting” but only on the worker mag adapter. You will have have to file away roughly 1/8 (.125) off of the top of the mag catch notch. Then slide the "mag                 adapter Spacer over the adapter down until in bottoms out on the lowest lip of the adapter.

The spacer and the filed notch will force the adapter & mag to sit lower in the blaster correcting the dart alignment issue. This allows for smoother cycling of darts into the breach. Still not slamfire speeds but battle reliable.

Please leave comments, and let me know if there are things I could do to improve form or function. And upload pics of your prints/builds and any remixes!
