This Mod Guide will cover the popular Spring Relocation Mod for the Nerf Vortex Proton, Vigilon and Praxis.
All 3 blasters use the same torsion spring powered disc launching system, so their modding methods are the similiar.
This mod is quite straightforward, simply disassemble the blaster casing and access the launcher mechanism, then relocate the torsion spring's securing leg one mounting point to the left. This increases the initial load in the torsion spring, thereby increasing the power of the shot.
Here are the reference photos for the spring relocation mods:
Nerf Vortex Proton [Internals]:
Note: You can also relocate the spring to the furthest left mounting point for additional load too.
Nerf Vortex Vigilon [Internals]:
Nerf Vortex Praxis [Internals]:
The spring relocation mod improves ranges on average by around 15ft. Quite effective for such an easy mod. :)
In addition, torsion springs with higher loads could also be used too. Here are examples of custom made aftermarket torsion springs for comparison:
Left to Right: Stock spring, 30% stronger spring, 120% stronger spring.
The stock torsion springs are already very strong in the first place, so i was only able to get the 30% stronger springs to fit and work properly... the other springs i tested with even higher loads were way too difficult to install and the internal components could not take the stress, which resulted in numerous cracked and broken parts in my test units.
With the 30% stronger spring installed, ranges improved by another approx. 10ft (over and above the spring relocation mod).
Note that wear and tear on the internal parts will naturally be much higher (especially with stronger springs), so modders will have to consider between performance improvements vs the lifespan of the blaster parts. :)
:: Sample Test Fire Data ::
Ranges are PTG: Parallel-To-Ground (Shoulder height, no elevation).
Distance is measured at where the disc lands (Average of 10 discs).
Vortex Proton/Vigilon/Praxis (Stock)
Average range = 55-65ft
Vortex Proton/Vigilon/Praxis (Spring Relocated)
Average range = 70-80ft
Vortex Proton/Vigilon/Praxis (Spring Relocated + Stronger Spring)
Average range = 80-90ft
Note that the test was done indoors with standard Vortex foam discs. The results are sample estimates for reference (your results may differ depending on materials and mod techniques used).
