07-m6 reverse button question

I have 2 m-6' 07's
i just bought the second one.
i noticed when i got it home, the reverse button was a "outty"
in other words, it sticks out. my other m-6 is like inverted so it is
harder to push (which is a good thing).

wondering if i take it a part, that they might of put a spring in it wrong to push it out, or did earlier models first have a outty vs a inny, or vis versa.

can you tell me what you have on your sleds , either m-6 or m-8

thanks
