okay, well first of all. Sorry for the over dramatic Post title.. how else would anyone click on it? xD

Anyway! Anyways..

I need help with creating Recoil.
So I was thinking about making a German Flak .88 Anti Aircraft gun and I was telling myself "man I have to add some Recoil every time it fires for better preformance features." I want to make a working gastube and everything.
Do I use a detacher? Or a piston? You tell me.

I am an XML modder and I am very familiar with Modding parts so if you recommend a modded part for me to use I can do that or if you want to make me one that's fine too.

Any help will be greatly obliged!
