Not sure if this is a Gunner Custom, but no claims were made by Fung of Gunner Airsoft  this time, so this might be a CYMA original. This seems a replica version of the one used by Mack at Future Weapons Cornershot episode, though we might  be wrong... "Another Full metal AEG from CYMA, Smooth gear box, 380+ fps!! Comes with hi-cap magazine and battery and charger. Come with Vltor style AK top rail, FN style hand grip, AKM flash hider."
