Thank you all for your feed back.
Based on this feedback we have decided to place this stock design on hold, we will not be developing it at this time. We do have one prototype that will be coming here so I can do an assessment and I will post a report. We may consider using this stock design on other projects in the future but it is simply not cost effective to manufacture her in small numbers.
We will be developing a Galil type folding stock for the WK180-C.
I stole this from RaptorX post above, thanks, this illustrates what I also have in mind.
