CWI Airsoft, an Airsoft Retailer based in Taiwan, has some fine selections for your WE M4 Gas Blowback rifle. We all know about the RA-Tech Wood stock which is coming very soon, but then there are other choices like their own wood kit for the M14 GBB-R. Both the RA-Tech and CWI versions cost the same, but if you don't have yet the WE M14 GBB-R as you're holding out for a full-wood version, then you're in luck.
