9mm SBR Build

[SABuzzard]

I'm putting together a suppressed 9mm SBR and need some help selecting a stock. What I'm looking for is as short as possible collapsed length, but still have the same (or as close to the same) extended length as a traditional M4 MilSpec. I realize you can't go any shorter than the buffer tube. Are there different length buffer tubes to be had? Does such an animal exist? Ideas?

I've never seen a shorter tube--they all appear to be the same length. I guess you could try cutting it down, but it would likely create problems with the buffer travel distance.
