They dont need to drill it, their 4 eye system is amazing. The extra set of eyes is conjoined with the detents. The extra eyes is set in the middle of the detents i presume, and the detents still work the way they normally do.
the quad eye system when engaged drains the battery like every eleventeen year old rec ball superstar on their mommy and daddys wallets. Killa detents while a big improvement to rubber nub detents in other guns wouldn't make much sense in the fusion. I would say the detents in the fusion are damn near perfect.
I had Kila's magnetic detents in my alias's, and loved them, it'd be another option for the Fusion, and you could customize your marker a little without buying the whole HC Kit, so I thought I'd bring it up....
And they make boards....

i wouldnt think the 4 eye system to would use so much voltage. Unless the board thats attach to the eyes does, because the eyes are pretty much LED's and they don't take much voltage. Thats why sometimes the gun still turns on and the LED still emit light but the solenoid barely/doesnt click. Meaning you have low batteries.
