Reapers Airsoft goes over this "Upgrade Version 2020" of the WE Airsoft MK16 which is based on the SCAR-L and comes with the Begadi CORE EFCS. Video is around 1 hour and 20 minutes so better grab something to drink and eat whilst watching... "Hello guys, today I have the WE MK16 S-AEG in the 2020 upgrade version with Begadi Core, Maple Leaf HopUp and better Piston Set for you in the video."
