With the WE AK gas blowback rifles now in production prior to delivery to airsoft retailers, CWI Airsoft gave us links to photos of the internals of the GBB. They say that these are already fully open bolt systema and  CO2 ready. Notice also the ribbed handguard up front which will mean that third party parts makers will now go into creating a wooden handguard for it. Plus, you'll notice that Red Star engraving.
