Last trigger topic (I promise)

[PieCars]

i've already made a couple of topics asking questions about the e trigger or whatever but this time i've got the last few questions i want to ask about a mr1 trigger.

I'm working on customizing my gun
1. Is the spyder pilot compatible with the mr-1 if i did a trigger swap
2. If so, where can I find a trigger for a pilot (not just the frame)
3. Would I have to drill holes for eyes, and which eyes would you guys recommend for it?
