Pneumag: Clippart MPA-3 part question

[derfalpha]

Does anyone know if there is a part similar to the Clippard MPA-3 part, but with more stroke?

What about an Autococker actuator?

how much longer do you need?

Do you need the other aspects the same?(ID, OD, spring return......)

why do you need a longer stroke for a pneumag?

I would need likely 9mm.

ID & OD can remain the same.

Spring return would definitely have to increase. Exactly how much i'm not sure because I don't have one in front of me. Springs aren't a problem anyway. You can find them anywhere.

I need a longer stroke because i'm toying with bullpup ideas. 9mm is what i've calculated so far.
