Great job Parry! (Hope I got your name right) This was a very helpful overview. What is the stock FPS? Is it low enough for HvZ or can it be modded to hit that 120 mark?
Around 160fps to 180fps dependant on region also if you want to change spring it accepts gel ball blaster springs very well due to its nature of having a gel ball blaster based origins
We have not tested every spring we can, However, our Nexus Pro X springs fit when cut down to length. A 1.4 or 1.6 spring and a SCAR might get you to 120 FPS cap
@lukegoodman5877, you've mentioned that the nexus pro x springs fit, but are there any other compatible springs on your shop? Maybe the Max Stryker or Seagull springs?
