Latest video from RA Tech which you can find the same at the Airsoft Taiwan YouTube Channel shows you the new stock adapter for the WE SCAR-L Gas Blowback made by SRU. The stock adapter allows you to install an AR stock to the SCAR-L, which according to the designers is much easier to use than the standard SCAR stock. It seems folding the stock feature is disabled once the adapter is mounted.

You can order this at the Airsoft Taiwan online store.
