How to open up the Huma TP and probe for the FX Guns?

[PlinkForFun]

Hi all,

I wanted to open up the probe and huma TP for my dreamline. I heard that some people get some pretty huge gains in fps. Basically, what did you use to open it up, and what were your results?

Thanks

Use a Dremel and take your time that's all. Insert a pellet in the barrel for a guideline as to how big you want to go. Good luck
