Hey! Great mod, I use it with KIS and I'm lovin' the heck out of it. Seems like the telescoping piston has a few bugs, though? Either the center of the piston will extend downward into the part it's attached to, or it will extend upwards through the outer column. I've never once had it work correctly...or what I am assuming correctly would be for this part, anyways. Other than that, I haven't had a single problem with this amazing mod (when is Squad just gonna go ahead make it a core feature???)
